Attached disk and tape drives appear to the host as standard DIGITAL storage architecture (DSA) devices. Disk allocation class is user- definable, with all attached disks sharing the class value. Tape allocation class is independently user-definable in the same manner. The HSD05 DSSI-to-SCSI bus adapter identifies itself as a node on the DSSI bus. The HSD05 DSSI-to-SCSI bus adapter identifies attached disk devices as RF72 or RA82 disk drives, and attached tape devices as TU81 tape drives. This identification is in device name only, and does not reflect actual device geometries. HSD05 DSSI-to-SCSI Bus Adapter Operation 1-5 1.1.2 Overview of HSD05 Operating Requirements/Limitations The HSD05 DSSI-to-SCSI bus adapter normally serves as a terminating end of the SCSI bus. Its factory-default SCSI node address, or SCSI ID, is 7. The HSD05 DSSI-to-SCSI bus adapter itself should only be removed when the power is off to all nodes on the DSSI bus that is attached to the HSD05 DSSI-to-SCSI bus adapter. Depending upon the complexity of the configuration, total DSSI bus length should be limited to 60 feet, with an HSD05 DSSI-to-SCSI bus adapter attached, to guarantee DSSI bus integrity. The HSD05 DSSI-to-SCSI bus adapter does not support dual pathing or failover operation for attached devices. The HSD05 DSSI-to-SCSI bus adapter does not sequence disk drives when spinning up. To minimize surge current to the power supply, spin up one or two drives at a time. 1.1.2.1 OpenVMS VAX Volume Shadowing The HSD05 DSSI-to-SCSI bus adapter supports host-based volume shadowing, but does not support controller-based shadowing assists. No HSD05 DSSI-to-SCSI bus adapter-based Redundant Array of Independent Disks (RAID) functionality is supported. The HSD05 DSSI-to-SCSI bus adapter identifies attached disk devices as RF72 or RA82 disk drives, and attached tape devices as TU81 tape drives. This does not affect the actual accessible device storage space. However, the following restrictions apply to creating shadow sets: · Due to device geometry differences, a disk drive served by the HSD05 DSSI- to-SCSI bus adapter cannot be part of a shadow set with true RF72 (or any other DSSI device) disk drives. · Shadow sets using HSD05 DSSI-to-SCSI bus adapter-served disk drives must be of the same SCSI device type, for example all RZ26, or all RZ26L, or all RZ28 disk drives. · Disk drives configured on an HSD05 DSSI-to-SCSI bus adapter may only be shadowed with disk drives that are also configured on an HSD05 DSSI-to- SCSI bus adapter; that is, a disk drive configured on a local SCSI adapter or on an HSC/HSJ-family controller may not be shadowed with a disk drive that is configured on an HSD05 DSSI-to-SCSI bus adapter. 1-6 HSD05 DSSI-to-SCSI Bus Adapter Operation 1.1.3 HSD05 DSSI-to-SCSI Bus Adapter Switches, Jumpers and Indicators The HSD05 DSSI-to-SCSI bus adapter module board contains switches, jumpers, and indicators, as shown in Figure 1-2. Table 1-2 through Table 1-4 list the jumper and switch settings and the indicator status. Figure 1-2 HSD05 DSSI-to-SCSI Bus Adapter Module Board HSD05 DSSI-to-SCSI Bus Adapter Operation 1-7 Table 1-2 lists the jumper settings for the HSD05 DSSI-to-SCSI bus adapter. All jumpers are installed at the factory and do not need to be changed during a normal installation of the HSD05 DSSI-to-SCSI bus adapter.

Locate the configuration switchpack, as shown in Figure 1-2. The device configuration switchpack contains 10 switch elements, divided into DSSI ID and SCSI ID sections as shown in Figure 1-2. Refer to Section 1.4.3.1 for detailed information on the MSCP/TMSCP unit numbers. 1.2.1 Selecting and Setting the DSSI ID The HSD05 DSSI-to-SCSI bus adapter is connected to the standard DSSI bus 0 on the VAX 4000 host computer and is externally accessable through the DSSI port on the connector panel to the left of the card cage. Each device on the DSSI bus requires a unique device address in the range of 0 through 7. The DSSI ID of the HSD05 is factory set to 0; you may need to change this ID to one that is currently not being used on your system. Table 1-6 lists the sections of SW2 used for setting the DSSI ID and the corresponding settings for each DSSI ID. On the switchpack, the closed position is with the switch in the down position, and the open position is with the switch in the up position. Table 1-6 HSD05 DSSI ID Switch Settings ------------------------------------------------------------ DSSI ID SW2-1 SW2-2 SW2-3 ------------------------------------------------------------ 0 Open Open Open (Default) 1 Open Open Closed 2 Open Closed Open 3 Open Closed Closed 4 Closed Open Open 5 Closed Open Closed 6 Closed Closed Open 7 Closed Closed Closed ------------------------------------------------------------ Use the following procedure to set the DSSI ID: 1. At the system console prompt, enter the console command SHOW DEVICE to determine the DSSI ID numbers currently active on the DSSI bus. HSD05 DSSI-to-SCSI Bus Adapter Operation 1-11 2. Select an unused DSSI ID number for the HSD05 DSSI-to-SCSI bus adapter. 3. Refer to Figure 1-2 and Table 1-3 to locate the DSSI ID switches on the device configuration switchpack. 4. Using a small blade screwdriver or similar tool, set the switches to the DSSI ID number selected in Step 2. 1.2.2 Selecting and Setting the SCSI ID The SCSI port plugs into the SCSI backplane connector (J30) when the HSD05 DSSI-to-SCSI bus adapter is installed in the card cage. This port must have a unique SCSI ID. The HSD05 DSSI-to-SCSI bus adapter is factory set to SCSI ID = 7 to give the adapter the highest priority on the SCSI bus. The other devices in the configuration must have SCSI ID numbers between 0 and 6. For normal operation, you do not need to reset the SCSI ID. Table 1-7 lists the sections of SW2 used for setting the SCSI ID and the corresponding settings for each SCSI ID. On the switchpack, the closed position is with the switch in the down position, and the open position is with the switch in the up position.

Refer to Figure 1-2 and Table 1-3 to locate the SCSI ID switches on the node configuration switchpack. 1-12 HSD05 DSSI-to-SCSI Bus Adapter Operation 3. Using a small blade screwdriver or similar tool, set the switches to the SCSI ID number selected in Step 1. 1.3 Applying Power to the HSD05 Apply power to the HSD05 DSSI-to-SCSI bus adapter as follows: 1. Place the power switch on the VAX 4000 system in the on position. 2. Verify that the HSD05 DSSI-to-SCSI bus adapter indicators (shown in Figure 1-2) are correctly lit as described in Table 1-4. 3. At the system console prompt, enter the console command SHOW DEVICE on the OpenVMS VAX system to verify that the HSD05 DSSI node address is online to the host system. 1.4 Setting Parameters for the HSD05 DSSI-to-SCSI Bus Adapter The OpenVMS diagnostic and utility protocol (DUP) utility provides a gateway to modifying HSD05 DSSI-to-SCSI bus adapter parameters and parameters for the devices connected to the HSD05. You can run this utility from either the system console or from the OpenVMS system prompt. Once a DUP connection to the HSD05 DSSI-to-SCSI bus adapter is established, the onboard PARAMS configuration utility is used to set and show HSD05 and device parameters. Section 1.5 contains procedures for using the HSD05 onboard device and diagnostic utility (UTILIT) during normal operation of the subsystem. In the following sections, user input is shown in boldface type in the examples. HSD05 DSSI-to-SCSI Bus Adapter Operation 1-13 1.4.1 Starting PARAMS from the Console Prompt on OpenVMS VAX Systems Use the following procedure to start PARAMS from the console prompt on OpenVMS VAX systems: 1.

Table 1-8 PARAMS Configuration Utility HSD05 DSSI-to-SCSI Bus Adapter Parameters ------------------------------------------------------------ Parameter Name Definition ------------------------------------------------------------ NODENAME HSD05 node name. This value must be unique among all systems in the VAXcluster system. The string cannot include the dollar sign ($) or underscore (_) characters, and cannot be longer than eight characters. The factory default for the node name is a unique six-digit number. SYSTEMID Specifies the lower order 32 bits of the 48-bit system identification number. The factory default for this identifier is the same as specified by the NODENAME parameter. DISK_ALCS Determines the device allocation class for all disk devices connected to the HSD05 DSSI-to-SCSI bus adapter. If disks are to be served to other nodes within the VAXcluster, this parameter must be non- zero and match the ALLOCLASS SYSGEN parameter on connected systems. The factory default for this parameter is zero. TAPE_ALCS Determines the device allocation class for all tape devices connected to the HSD05 DSSI-to-SCSI bus adapter. If tapes are to be served to other nodes within the VAXcluster, this parameter must be non- zero and match the ALLOCLASS SYSGEN parameter on connected systems. The factory default for this parameter is zero. INTERVAL Controls the rate at which SCSI device scanning is done. This value is only used if SCANNING is enabled. The factory default for this parameter is 60 seconds. NUMPOLL Controls the number of SCSI devices to look for during each INTERVAL. This parameter is currently not implemented but may be activated in a future revision of the firmware. The factory default for this parameter is 7, which scans for all available units at each interval. UNIT_OFFSET Helps to differentiate devices when a system has two DSSI buses. Unit offset is specified as the value to be used in the thousands position of the MSCP unit ID, such as x for DIAx210. This offset is automatically created by the system. The unit offset values must be unique for each DSSI bus on the system. The factory default for this parameter is 0. SYNC_RATE The rate in MHz that data is transferred during the data transmission phase between target and host. The factory default for this parameter is 7 MHz. (continued on next page) HSD05 DSSI-to-SCSI Bus Adapter Operation 1-17 Table 1-8 (Cont.) PARAMS Configuration Utility HSD05 DSSI-to-SCSI Bus Adapter Parameters ------------------------------------------------------------ Parameter Name Definition ------------------------------------------------------------ MAX_HOSTS Determines the maximum number of hosts with which the HSD05 DSSI-to-SCSI bus adapter can communicate. This parameter is primarily used for disk and tape credit allotment. For best performance, set this parameter to the maximum number of hosts to be used. Digital supports up to three hosts (the factory default) in a multihost HSD05 DSSI-to-SCSI bus adapter configuration. FASTSCAN Reduces the SCSI SELECT timeout to a much smaller value, with the default timeout set at 250 milliseconds. This parameter is currently not implemented. The factory default for this parameter is 0 (disabled). SCANNING Enables/disables the HSD05 DSSI-to-SCSI bus adapter 's ability to scan for newly connected devices. If scanning is disabled, the HSD05 DSSI-to-SCSI bus adapter only does one scan for devices at power up, and does not look for new devices every INTERVAL seconds. The factory default for this parameter is 1 (enabled). DISCONNECT Enables/disables the ability to disconnect all SCSI devices connected to the HSD05 DSSI-to-SCSI bus adapter. When only one device is connected to the HSD05 DSSI-to-SCSI bus adapter, this parameter can be disabled for better performance. The factory default for this parameter is 1 (enabled). POWERONRST Enables/disables issuing a SCSI BUS RESET command when the system is turned on. The factory default for this parameter is 1 (enabled). TRYSYNC Enables/disables synchronous negotiation when a SCSI device is initialized. For very short cables, synchronous negotiation can be disabled for better performance in ASYNC mode rather than SYNC mode. The factory default for this parameter is 1 (enabled). SPIN_DOWN Enables/disables the ability of the HSD05 DSSI-to-SCSI bus adapter to spin down drives or eject media when the operating system issues a spin down command, such as the OpenVMS command DISMOUNT/UNLOAD. The factory default for this parameter is 1 (enabled). TAGGED_CMD Enables/disables simple tag queuing. The factory default for this parameter is 1 (enabled). (continued on next page) 1-18 HSD05 DSSI-to-SCSI Bus Adapter Operation Table 1-8 (Cont.) PARAMS Configuration Utility HSD05 DSSI-to-SCSI Bus Adapter Parameters ------------------------------------------------------------ Parameter Name Definition ------------------------------------------------------------ TRUNCATE This parameter truncates the number of blocks to be divisible by 126. The factory default for this parameter is 1. This default supports faster OpenVMS volume shadowing catch-up time. A value of 0 selects no truncation for compatibility with other third-party units. DEVICE_TYPE This parameter applies to disk drives only. When disabled (set to 0), the device type reported by the HSD05 DSSI-to-SCSI bus adapter to the OpenVMS operating system is an RA82 disk drive. When enabled, the HSD05 DSSI-to-SCSI bus adapter reports the RF72 device type. The device type reported to the host does not affect the accessible disk space. The factory default for this parameter is 1 (enabled). IMMEDIATE When enabled, this parameter causes the IMMEDIATE bit in the SCSI START and STOP commands to be set. Note that when IMMEDIATE is set to 0, the OpenVMS prompt does not return until the drive's media is ejected or the drive has spun down. The factory default for this parameter is 1 (enabled). CMD_P3 Determines the type of transmission used on the DSSI bus for single host configurations only: 0 for standard and 1 for fast mode. This is a hidden parameter that is not displayed by the PARAMS SHOW /ALL, SHOW /SCSI, or SHOW /SCS commands. To display this parameter value, use the SHOW CMD_P3 command in the PARAMS utility. The factory default for this parameter is 1 (fast mode). TMARKSEARCH Enables fast tape mark searching. Because some tape drives perform slowly while looking for tape marks during operations on large space records, a skip tapemark is done instead. Because the device does not report the number of records skipped between tapemarks, the position (object) count is not correct when this parameter is enabled. The factory default for this parameter is 0 (disabled). SHORT_TMARK Enables/disables writing short filemarks on Exabyte devices. When disabled, all filemarks are written as large filemarks. The factory default for this parameter is 1 (enabled). (continued on next page) HSD05 DSSI-to-SCSI Bus Adapter Operation 1-19 Table 1-8 (Cont.) PARAMS Configuration Utility HSD05 DSSI-to-SCSI Bus Adapter Parameters ------------------------------------------------------------ Parameter Name Definition ------------------------------------------------------------ WT_PROTECTED Enables/disables write protection for each SCSI ID. When disabled (set to 0), it allows read-write access to a SCSI ID, and when enabled, it restricts access to read only. This parameter is in the form of a boolean matrix, with the leftmost position representing a SCSI ID of 7, and the rightmost position representing a SCSI ID of 0. For example, a WT_PROTECTED setting of 00000001 allows read-write access to SCSI IDs 1 through 7 and read only access to SCSI ID 0. The factory default for this parameter is 00000000 (no devices write protected). ONLINE Controls whether devices are online or offline to the host. This parameter is in the form of a boolean matrix, with the leftmost position representing SCSI ID=7, and the rightmost position representing SCSI ID=0. For example, an ONLINE setting of 10000000 sets SCSI IDs 0 through 6 offline and SCSI ID 7 online. The factory default for this parameter is 11111111 (all devices online). NAME_ALGRM This parameter is fully described in Section 1.4.3.1. SCSI_ID_X Used in conjunction with the NAME_ALGRM parameter to set alternative device names for each SCSI ID. ------------------------------------------------------------ 1.4.3.1 The NAME_ALGRM Parameter The NAME_ALGRM parameter toggles between the HSD05 DSSI-to-SCSI bus adapter 's standard device naming convention and an alternative convention based upon the TMSCP/MSCP unit number. When NAME_ALGRM is set to the default of 0, the HSD05 DSSI-to-SCSI bus adapter uses its standard naming algorithm, which assigns a unit number based on the following parameters: · Unit offset (w)--A unique number (0 - 9) for each host DSSI bus. This parameter can be used to modify bus numbering conflicts in multiple DSSI bus configurations. It is recommended that this parameter be set to the DSSI bus number. · DSSI ID (x)--The DSSI device address for the HSD05 DSSI-to-SCSI bus adapter. · SCSI ID (y)--The SCSI device address for the storage device. This is set by the bus node ID plug on the device bezel. · SCSI logical unit number (z)--The device address of a subdevice attached to a SCSI device identified by SCSI ID y (usually 0). 1-20 HSD05 DSSI-to-SCSI Bus Adapter Operation Setting NAME_ALGRM to 1 activates the alternative naming algorithm, which assigns a unit number in conjunction with the SCSI_ID_X parameter. These two conventions are summarized in the next table: ------------------------------------------------------------ NAME_ ALGRM Setting Formula for MSCP /TMSCP Unit Number 1 Example ------------------------------------------------------------ 0 wxyz 1234 where: w = 1, x = 2, y = 3, z = 4 1 scsi_id_x + ((w + 1) * z) Assuming w = 1, z = 1, and the scsi_id_x parameter values are as follows: SCSI ID SCSI_ID_X MSCP/TMSCP Unit Number 0 0 2 1 10 12 2 20 22 3 30 32 4 40 42 5 50 52 6 60 62 7 70 72 ------------------------------------------------------------ 1 w = UNIT_OFFSET parameter x = DSSI ID y = SCSI ID z = SCSI logical unit number (LUN) ------------------------------------------------------------ HSD05 DSSI-to-SCSI Bus Adapter Operation 1-21 1.4.4 Set Device Parameters Using the PARAMS Configuration Utility The HSD05 DSSI-to-SCSI bus adapter operating parameters are initialized at the factory. Depending upon the specific configuration of your system or cluster, the following device parameters (at the minimum) may need to be set: · NODENAME--A unique six character DSSI node name for the HSD05. · DISK_ALCS--It is recommended that this parameter be set to match the ALLOCLASS VMS SYSGEN parameter on connected systems. · TAPE_ALCS--It is recommended that this parameter be set to match the ALLOCLASS VMS SYSGEN parameter on connected systems. · UNIT_OFFSET--It is recommended that this parameter be set to the DSSI bus number. ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Device unit numbers as seen by the hosts must be unique throughout the system or cluster containing the HSD05 DSSI-to-SCSI bus adapter. If a unit number is added that overlaps the unit number of another device on another controller in the system or cluster, all the devices on that other controller can disappear. In this event, the unit number conflict should be resolved, and controller power should then be cycled off/on to make the devices available to the host system or cluster. ------------------------------------------------------------ Use the following procedure to set new device parameters: 1. At the PARAMS prompt, enter the parameters you wish to change; for example: PARAMS> SET NODENAME HSD1 PARAMS> SET DISK_ALCS 10 In this example, the NODENAME has been changed to HSD1 and the DISK_ ALCS parameter set to 10. 1-22 HSD05 DSSI-to-SCSI Bus Adapter Operation 2. Enter the SHOW /ALL command to display your changed parameters. PARAMS> SHOW /ALL Parameter Name Active Min. Max.

Save the changes to nonvolatile memory with the following command: PARAMS> WRITE 4. Reboot the HSD05 DSSI-to-SCSI bus adapter to use the new parameters. PARAMS> RESTART 5. Reboot the host systems to update the host device tables to the new settings for the HSD05 DSSI-to-SCSI bus adapter and attached devices. Verify that any parameter changes are shown at both the console and within the OpenVMS operating system. ------------------------------------------------------------ CAUTION ------------------------------------------------------------ The HSD05 DSSI-to-SCSI bus adapter returns a limited set of device type identification names to the host. All attached tape drives are identified as TU81 (MUAxxx). All attached disk drives are normally identified as RF72 (DIAxxx); this can be changed to identification as RA82 (DUAxxx) by setting the HSD05 parameter DEVICE_TYPE to 0. These device types as reported to the host do not affect actual accessible device storage space. Due to device geometry differences, a disk drive served by the HSD05 DSSI-to-SCSI bus adapter cannot be part of a shadow set with true RF72, or any other DSSI disk drives. Shadow sets using HSD05 DSSI-to-SCSI bus adapter-served disk drives must be of the same SCSI device type; for example, all RZ26L or all RZ28 disk drives. ------------------------------------------------------------ HSD05 DSSI-to-SCSI Bus Adapter Operation 1-23 1.5 HSD05 Device Utilities The HSD05 onboard utilities (UTILIT) allow you to monitor, format, qualify, and exercise SCSI devices from the system console or the OpenVMS operating system.

HSD05 DSSI-to-SCSI Bus Adapter Operation 1-33 1.5.3.7 The QUALIFY Command It is recommended that you run one or more qualification passes with the QUALIFY command after a drive is formatted. The device to be qualified must first be selected with the SELECT command. Syntax The following is the syntax of the QUALIFY command: QUALIFY device_name [/write] The symbol device_name refers to a valid MSCP device label for a direct access device. Direct access devices, such as disk drives, are specified with the ``DIA'' prefix to the device label, for example, ``DIA100.'' The /WRITE qualifier selects a write-read qualify operation. The QUALIFY command can run either read-only or write-read (using the /WRITE qualifier). The write-read qualification operation consists of writing sequential 32-kilobyte chunks of data to the device and then reading it back. This sequence repeats until all logical blocks on the device have been written and read. Bad blocks are replaced and retested in a write-read qualify operation. You should use the write-read qualifier for newly formatted drives. Running QUALIFY in the read-only mode verifies media readability and consistency, but does not alter any drive data. You are prompted to confirm the qualify operation on the selected device. Answering ``N'' or ``NO'' aborts the operation with no change to the data on the device. Answering ``Y'' or ``YES'' to this prompt starts the qualify operation on the device. QUALIFY runs until it is terminated with the ABORT command or until the HSD05 DSSI-to-SCSI bus adapter is powered off. The number of passes made is displayed on a pass counter. 1-34 HSD05 DSSI-to-SCSI Bus Adapter Operation Example 1-7 shows a write-read qualification run using the QUALIFY command.

HSD05 DSSI-to-SCSI Bus Adapter Operation 1-35 1.5.3.8 The DISKTEST Command The DISKTEST command performs an exercise on the selected disk device. You should run DISKTEST on all newly formatted and qualified devices. The device to be exercised must first be selected with the SELECT command. Syntax The following is the syntax of the DISKTEST command: DISKTEST device_name [/write] The symbol device_name refers to a valid MSCP device label for a direct access device. Disk drives are specified with the ``DIA'' prefix to the device label. The /WRITE qualifier selects a write-read disktest operation. The DISKTEST command can run either read-only or write-read (using the /WRITE qualifier) tests. The write-read DISKTEST operation consists of writing to randomly selected logical blocks and verifying the data. This sequence repeats until all logical blocks on the device have been written and read, then the test begins again until the ABORT command is entered to terminate the DISKTEST. You must perform a write-read disktest to write data to the disk before you perform the read-only disktest. You are prompted to confirm the DISKTEST operation on the selected drive. Answering ``N'' or ``NO'' aborts the operation with no change to the data on the device. Answering ``Y'' or ``YES'' to this prompt starts the DISKTEST on the device. Running the DISKTEST operation with the /WRITE qualifier replaces media errors when encountered. If other types of errors occur, the test is stopped and the error condition is displayed in the Maint Status field of the display. The DISKTEST test operation runs until it is terminated with the ABORT command or until the HSD05 DSSI-to-SCSI bus adapter is powered off. 1-36 HSD05 DSSI-to-SCSI Bus Adapter Operation Example 1-8 shows a DISKTEST run.

HSD05 DSSI-to-SCSI Bus Adapter Operation 1-37 1.5.3.9 The TAPETEST Command This command performs a tape exercise on the selected tape device. This test requires enough tape to accommodate 10 megabytes of 1-kilobyte blocks. The device to be exercised must first be selected with the SELECT command. Syntax The following is the syntax of the TAPETEST command: TAPETEST device_name The symbol device_name refers to a valid TMSCP device label for a direct access or sequential access device. Tape drives are specified with the ``MUA'' prefix to the device label. The TAPETEST exercise consists of writing, rewinding, and reading each section of tape, up to but not including a filemark. Block sizes start at 32 kilobytes and are halved on each successive write/rewind/read pass. The test is restarted when the block size reaches 1 kilobyte. You are prompted to confirm the TAPETEST operation on the selected drive. Answering ``N'' or ``NO'' aborts the operation with no change to the data on the device. Answering ``Y'' or ``YES'' to this prompt starts the TAPETEST operation on the device. The TAPETEST operation replaces media errors when encountered. If other types of errors occur, the test is stopped and the error condition is displayed in the Maint Status field of the display.

The HSD05 DSSI-to-SCSI bus adapter uses a system of onboard LED indicator codes to indicate the source of an internal fault. You can also use the OpenVMS Analyze/Error utility to read an HSD05 error log for information about devices connected to the HSD05 DSSI-to-SCSI bus adapter. 1.6.1 LED Indicators The location of the LED indicators (DS1 through DS4) is shown in Figure 1-3. During normal operation, these indicators are behind the module cover and are not visible. ------------------------------------------------------------ CAUTION ------------------------------------------------------------ The HSD05 DSSI-to-SCSI bus adapter module cover should only be removed for service or maintenance. This cover needs to be in place for proper air flow and cooling, and to meet international regulatory requirements. ------------------------------------------------------------ 1-46 HSD05 DSSI-to-SCSI Bus Adapter Operation Figure 1-3 HSD05 DSSI-to-SCSI Bus Adapter Module Board When the HSD05 DSSI-to-SCSI bus adapter boots, red indicator DS2 blinks for 15 seconds before it shuts off. If this indicator blinks for more than 15 seconds, it indicates that the onboard diagnostics have found a fault. The fault code is read out as a two-digit error code on the indicators; each digit of the code is indicated by the number of times the indicator blinks. The first digit of the code is separated from the second digit by a one-second pause. A two-second pause separates the error code from its next repetition. This code is repeated until reset by a power-off of the HSD05 DSSI-to-SCSI bus adapter. HSD05 DSSI-to-SCSI Bus Adapter Operation 1-47 Table 1-9 lists the serviceable error codes and the associated problem. For all other error codes, recheck the integrity of all bus terminator and cable connections. If these actions do not resolve the problem, replace the HSD05 DSSI-to-SCSI bus adapter. Table 1-9 HSD05 LED Indicator Codes ------------------------------------------------------------ Code Problem Resolution ------------------------------------------------------------ 11 DSSI port problem Ensure that DSSI termination power is supplied by either the host bus or the HSD05 DSSI-to-SCSI bus adapter. Check all DSSI bus connections and terminations. 12 SCSI port problem Ensure that SCSI termination power is supplied by either the host bus or the HSD05 DSSI-to-SCSI bus adapter. Check all SCSI bus connections and terminations. ------------------------------------------------------------ 1.6.2 HSD05 Error Logs The HSD05 DSSI-to-SCSI bus adapter logs error conditions in the OpenVMS error log file ERRLOG.SYS. To retrieve this information, use the OpenVMS command ANALYZE/ERROR_LOG. Refer to the applicable OpenVMS documentation to read this error log when troubleshooting the HSD05 DSSI- to-SCSI bus adapter. The HSD05 DSSI-to-SCSI bus adapter reports the following two types of error logs: · Type 1 error logs are SCSI port related. · Type 2 error logs are SCSI command related. For each of the types of error logs, there are also separate formats for disk and tape devices. 1-48 HSD05 DSSI-to-SCSI Bus Adapter Operation The following two tables contain information to be used in interpreting HSD05 DSSI-to-SCSI bus adapter errors during OpenVMS error log analysis: · Table 1-10 lists the possible SCSI port error codes that may be found in the error logs generated by the HSD05 DSSI-to-SCSI bus adapter. · Table 1-11 lists the SCSI bus phases reported by the HSD05 DSSI-to-SCSI bus adapter.

HSD05 DSSI-to-SCSI Bus Adapter Operation 1-55 2 ------------------------------------------------------------ Operating the RZ-series Integrated Storage Element Options This chapter tells you how to operate the RZ-series integrated storage element (ISE) options that are supported by the HSD05 DSSI-to-SCSI bus adapter. 2.1 Introduction The following RZ-series options are supported by the HSD05 DSSI-to-SCSI bus adapter in the BA400-based enclosures: · RZ26L disk drive · RZ28 disk drive · RZ73 disk drive · RZ74 disk drive Refer to Table 1-1 for the option number and a description of these ISEs. To use any mass storage device, you must properly identify the device to your operating system and use appropriate operating system commands. Refer to your system software documentation for details. ------------------------------------------------------------ Note ------------------------------------------------------------ Refer to Section 1.4.3 and Section 1.4.4 for information on displaying or setting device parameters. ------------------------------------------------------------ Using the dual-disk RZ, your system can have up to seven RZ-series ISEs or up to five RZ-series ISEs and a tape drive. Operating the RZ-series Integrated Storage Element Options 2-1 ------------------------------------------------------------ Note ------------------------------------------------------------ Some RZ ISEs have a dual-disk capability: Two separate ISEs can share the same mass storage cavity and front panel. ------------------------------------------------------------ When your system has multiple ISEs, you should separate them according to function. For example, if your system has two ISEs, you may want to use them as follows: · ISE 0 contains the operating system and applications installed on the system. · ISE 1 contains work areas for each user with an account on the system. 2.2 RZ-Series Controls and Indicators Each RZ-series ISE has controls and indicators on its front panel. To access them, open the upper system door (top key position). ------------------------------------------------------------ Note ------------------------------------------------------------ If your system has less than the maximum number of ISEs, a blank ISE front panel with no controls or indicators covers the empty ISE cavities. Such panels are required to meet international regulatory standards and airflow requirements. If your system has a 3.5-inch RZ-series ISE with only one disk, one set of controls has a blank bus node ID plug and its indicators do not light. ------------------------------------------------------------ 2-2 Operating the RZ-series Integrated Storage Element Options Figure 2-1 shows the RZ-series ISE front panels. Figure 2-1 RZ-series ISE Front Panels Each 5.25-inch RZ-series ISE has a bus node ID plug on its front panel. Each 3.5-inch RZ-series ISE has the following controls and indicators (there are two sets of controls and indicators, as 3.5-inch RZ-series ISEs can have two disks behind the one front panel). · Bus node ID plug · Fault indicator · Run/Ready indicator Bus node ID plugs identify the bus node number of each ISE to the system, as well as the unit number by default. Bus node numbers are configured at the factory in consecutive order from right to left. Operating the RZ-series Integrated Storage Element Options 2-3 Table 2-1 lists the RZ-series ISE controls and indicators. Table 2-1 RZ-Series ISE Controls and Indicators ------------------------------------------------------------ Control Position Function ------------------------------------------------------------ Bus node ID plug Installed Identifies bus node ID number (unit number) of ISE to system.

For the RZ-series ISEs, you set write-protection using VMS commands. Your system disk (the ISE containing system software) and ISEs containing work areas for users should be write-enabled, the normal setting. Since the RZ-series ISE does not have a Write-Protect button, the software write-protect is the primary method for write-protecting an RZ-series ISE. The software write-protect uses the VMS DCL MOUNT command with the /NOWRITE qualifier, as shown below: MOUNT/SYSTEM/NOWRITE device_name volume_label logical_name In this command, device_name is the device name, as shown using the VMS DCL command SHOW DEVICE DI, volume_label is the volume label for the device, and logical_name is the logical name of the device; for example: $ MOUNT/SYSTEM/NOWRITE $1$DIA10: OMEGA OMEGA$DISK The above command line software write-protects device $1$DIA10. Dismounting and then remounting the device (without using the /NOWRITE qualifier) write-enables the device. Use the VMS DCL command SHOW DEVICE DI to check the protection status of the drive. A write-protected drive shows a device status of Mounted wrtlck. Refer to your VMS documentation for more information on using the MOUNT utility. ------------------------------------------------------------ CAUTION ------------------------------------------------------------ When you dismount and then mount the device again, it is no longer write-protected. ------------------------------------------------------------ 2-6 Operating the RZ-series Integrated Storage Element Options 2.4.2 Hardware Write-Protect for RZ-series ISEs The hardware write-protect provides a more permanent write-protection than the software write-protect. Once you hardware write-protect an RZ-series ISE, it remains write-protected, regardless of the availability of the operating system or if the system is powered-down. In addition, a hardware write-protect cannot be removed by using the MOUNT or DISMOUNT commands. You should consider hardware write-protecting an RZ-series ISE when: · You want to write-protect an RZ-series ISE when the VMS operating system is not available, such as before running the MicroVAX Diagnostic Monitor (MDM). · You want to ensure that an RZ-series ISE remains write-protected, since the hardware write-protect cannot be removed by the VMS MOUNT command and remains in effect even if the operating system is brought down. Refer to Section 1.4.3 and Section 1.4.4 to display and set the HSD05 operating parameters. Refer to Table 1-8 for a detailed definition of the WT_PROTECTED parameter. Operating the RZ-series Integrated Storage Element Options 2-7 2.5 Changing the Bus Node ID Plugs Spare bus node ID plugs are supplied with your system. Use them to renumber your ISEs if you · Reconfigure your system with an expander · Create a DSSI VAXcluster configuration The ID plugs have prongs on the back that indicate the bus node number (unit number) of the ISE. · To remove a plug, grasp it firmly and pull straight out (see Figure 2-2). · To insert a plug, align the two center prongs with the two center slots and press the plug into the slots (see Figure 2-2). Figure 2-2 Removing and Inserting a Bus Node ID Plug Use these rules for renumbering your storage devices. · For each DSSI bus, do not duplicate bus node numbers for your storage devices/adapters. For Bus 0, you can have only one device identified as node 0, one device as 1, and so on. For Bus 1, you can have only one device identified as node 0, one device as 1, and so on. 2-8 Operating the RZ-series Integrated Storage Element Options · That rule also applies to DSSI VAXcluster configurations. All DSSI bus node numbers for storage devices and DSSI adapters must be unique in a shared DSSI bus. · The RZ-series ISEs are numbered in increasing order from right to left beginning with zero. · DSSI adapters use the highest available bus nodes. The next highest available node (usually five) is reserved for a TZ/TLZ-series tape drive. · If more than one DSSI bus is used and your system is using a nonzero allocation class, assign new Mass Storage Control Program (MSCP) unit numbers for devices on all but one of the DSSI buses. The unit numbers for all DSSI devices connected to a system's associated DSSI buses must be unique. ------------------------------------------------------------ Note ------------------------------------------------------------ If you change the bus node ID plugs while your system is operating, you must turn off the system and then turn it back on for the new plug positions to take effect. ------------------------------------------------------------ Operating the RZ-series Integrated Storage Element Options 2-9 3 ------------------------------------------------------------ Operating the TZ86 and TZ87 Cartridge Tape Subsystems This chapter explains how to operate the TZ86 and TZ87 cartridge tape options that are supported by the HSD05 DSSI-to-SCSI bus adapter. 3.1 TZ86 and TZ87 General Description The TZ86 and TZ87 drives are streaming tape drives. The TZ86 drive can store up to 6.0 GB of data on a CompacTape III cartridge. The TZ87 drive can store up to 10.0 GB of data without compression and 20 GB of data with compression, assuming a 2:1 compression ratio, on a CompacTape III cartridge. The TZ86 and TZ87 cartridge tape subsystems are used primarily for data backup, for data archiving, and for loading software onto computer systems. The TZ86 and TZ87 cartridge tape subsystems use the SCSI bus. The TZ86 tape drive writes 56 pairs of tracks--112 tracks total--on the CompacTape III. The drive reads and writes data in a two-track parallel, serpentine fashion, traveling the entire length of tape on two tracks (at about 100 inches per second). The drive then steps the head and reverses tape direction and continues to read/write on the next two tracks. The TZ87 tape drive writes 64 pairs of tracks--128 tracks total--on the CompacTape III. The drive reads and writes data in a two-track parallel, serpentine fashion, traveling the entire length of tape on two tracks (at about 110 inches per second). The drive then steps the head and reverses tape direction and continues to read/write on the next two tracks.

The CompacTape III is supplied with a: · Set of slide-in labels for cartridges · Cartridge handling information sheet 3.5.1 Cartridge Write-Protect Switch The CompacTape III cartridge has a write-protect switch to prevent accidental erasure of data. Before loading the tape cartridge into the drive, position the write-protect switch on the front of the cartridge (Figure 3-2). The switch can move to the: · Left, so the cartridge is write-protected · Right, so the cartridge is write-enabled When the switch is moved to the left and the small orange rectangle is visible, data cannot be written to the tape. Beneath the orange rectangle is an arrow over two lines on the write-protect switch. The arrow over the two lines symbolizes that data cannot be written to the tape. On the right side of the write-protect switch is another symbol, an arrow over one line. This symbol indicates that if the write-protect switch is moved to the right, data can be written to the tape. 3-8 Operating the TZ86 and TZ87 Cartridge Tape Subsystems Figure 3-2 shows the CompacTape III cartridge and the write-protect switch. Figure 3-2 CompacTape III Cartridge Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3-9 3.5.2 Data Protection If you move the cartridge write-protect switch to the left, the drive turns on the write protect LED immediately. However, if the drive is writing to the tape, the write protect does not take effect until the write is completed. Table 3-6 describes what happens to data protection when you move the write- protect switch before loading the cartridge. Table 3-6 Before Loading the Cartridge ------------------------------------------------------------ If you move the write-protect switch. . .

This includes density changes, since they only occur when writing from BOT. ------------------------------------------------------------ 3.6.1 TZ87 Density Selection To select density with the TZ87: 1. Insert the tape into the drive. The yellow Tape in Use indicator blinks while the tape loads and calibrates. 2. After calibration completes, the yellow Tape in Use indicator remains lit. 3. Press the Density Select switch once to enter the density select mode. The Density Override indicator and the indicator of the tape's actual density lights. 4. Press the Density Select switch again to toggle through the different density options. Stop when you reach the selected density. The selected density indicator blinks and the tape's actual density indicator remains steady. 5. After the tape is written to in the selected format, the selected density indicator lights steadily, and the previous density indicator shuts off. If you have installed a tape with a prerecorded TK85 density and you use the density selection button to select TZ87 density, the following occur: · The TK85 indicator remains lit, indicating that the density selection of the current tape has not changed yet. · The TZ87 indicator blinks, indicating that a density change is pending. · The density override indicator is lit, indicating that a density selection has been made from the front panel. When a write from BOT occurs, the following occur: · The TK85 indicator goes off. · The TZ87 indicator becomes steady. · The density override indicator remains lit. 3-12 Operating the TZ86 and TZ87 Cartridge Tape Subsystems Density selection occurs according to the following rules: READ WRITE APPEND The density selected reflects the density of the tape already in the drive. WRITE from BOT The density selected may occur via the use of the front panel Density Select button. Using the Density Select button always overrides the existing density of the tape. If the Density Select button is not used, the density selected is the native default, TZ87 mode (compression enabled). ------------------------------------------------------------ Caution ------------------------------------------------------------ Regardless of the operating conditions, a write from BOT destroys existing data on the tape. ------------------------------------------------------------ ------------------------------------------------------------ Note ------------------------------------------------------------ You can use the drive's control panel at various times, not just after loading a tape. Density selection is inactive until a write command is issued at Beginning of Tape (BOT). The controller remembers the density selection state until you do one of the following: · Change the density selection. · Unload the tape. ------------------------------------------------------------ Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3-13 Table 3-10 lists the results of different density selection actions. Table 3-10 Results of Density Selection ------------------------------------------------------------ If. . . Then . . . ------------------------------------------------------------ You did not use the density select button The indicators show the actual density when the tape is reading and writing. The drive density indicator lights steadily and the density override indicator is off. You used the density select button, and if the actual tape density is the same as the density you selected The indicator for both the actual density and density override indicators are lit. For example, if the actual tape density is TZ87 and the selected tape density is TZ87, then the indicator next to TZ87 lights. You used the density select button, and if the actual tape density differs from the density selected: 1. The density override indicator lights steadily. 2. The indicator next to the actual density lights steadily. 3. The indicator next to the selected density blinks. For example if the actual tape density is TZ87 and the selected density is TK86, the TZ87 indicator lights steadily, the TK86 indicator blinks, and the density override indicator remains steady. After writing from BOT begins, the TZ87 indicator turns off, the TK86 indicator lights steadily and the density override indicator lights steadily. ------------------------------------------------------------ 3.6.2 TZ86 Density Selection In HSD05 applications, the TZ86 tape drive defaults to using TK86 format (high density) for all writes from Beginning of Tape (BOT). When you append data to a tape cartridge written in TK85 format, the current media density is used. 3-14 Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3.7 Loading a CompacTape III Cartridge The directions for loading a cartridge into the drive are printed on the front of the drive. The following are more detailed steps for loading a cartridge (Figure 3-3): 1. When the green Operate Handle light is on steadily, pull the cartridge insert /release handle open. 2. Insert the cartridge and push it into the drive. 3. Push the handle closed. The green Operate Handle light turns off and the yellow Tape in Use light blinks to show the tape is loading. When the tape is at the beginning-of-tape (BOT) marker, the yellow Tape in Use light turns on steadily. The tape is now ready for use. Figure 3-3 shows how to load a CompacTape III cartridge into the drive. Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3-15 Figure 3-3 Loading a CompacTape III Cartridge Whenever the yellow Tape in Use light is on steadily, the tape is ready to use. When the tape is being read, written, or rewound, the yellow Tape in Use light blinks. 3-16 Operating the TZ86 and TZ87 Cartridge Tape Subsystems Use Table 3-11 to determine what is happening during cartridge use. Table 3-11 During Cartridge Use (Top Front Panel Lights) ------------------------------------------------------------ If. . . It means. . . ------------------------------------------------------------ The yellow Tape in Use light is on steadily A cartridge is loaded, but the tape is not moving.

To unload a cartridge from the drive (Figure 3-4): 1. Press the Unload button (or issue the appropriate system software command). The yellow Tape in Use indicator blinks as the tape rewinds. 2. When the green Operate Handle light turns on (the beeper also sounds), pull the cartridge insert/release handle open to eject the cartridge. 3. Remove the cartridge. 4. Push the handle closed. ------------------------------------------------------------ CAUTIONS ------------------------------------------------------------ Remove a cartridge from the drive before turning off host system power. Failure to remove a cartridge can result in cartridge and drive damage. When you remove the cartridge from the drive, return the cartridge to its plastic case to prolong the cartridge life. ------------------------------------------------------------ 3-18 Operating the TZ86 and TZ87 Cartridge Tape Subsystems Figure 3-4 Unloading a CompacTape III Cartridge Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3-19 3.9 Preserving CompacTape III Cartridges For longer life of recorded or unrecorded cartridges, store cartridges in a clean environment with the following conditions: · Do not drop or bang the cartridge. Doing so can displace the tape leader, making the cartridge unusable and possibly damaging the drive. · Keep tape cartridges out of direct sunlight and away from heaters and other heat sources. · Store tape cartridges in temperatures between 10°C and 40°C (50°F to 104°F). For longer cartridge life, always store the cartridge in its plastic container and in room environment conditions of 22°C ± 4°C (72°F ± 7°F). · If the tape cartridge has been exposed to heat or cold extremes, stabilize the cartridge at room temperature for the same amount of time it was exposed--up to 24 hours. · Do not place cartridges near electromagnetic interference sources, such as terminals, motors, video, or X-ray equipment. Data on the tape can be altered. · Store tape cartridges in a dust-free environment where the relative humidity is between 20% and 80%. For longer cartridge life, store the cartridge at 40% ± 20% relative humidity. · Place an identification label only in the slide-in slot on the front of the cartridge. · Do not adhere labels to the cartridge anywhere except in the slide-in slot. 3-20 Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3.10 Using the CleaningTape III Cartridge The CleaningTape III is a 4- 1 = 8-inch square, light yellow, plastic cartridge containing 1200 feet of 1= 2-inch cleaning tape. See Table 3-12 for information on using the CleaningTape III. Your CleaningTape III is supplied with a: · Slide-in label that has 20 boxes, each for marking a check after cartridge use. · Cartridge handling information sheet You can use the CleaningTape III cartridge 20 times before it expires. The word expire does not pertain to an expiration date. Expire means that there is no unused cleaning area left on the tape. To record the number of uses, mark a check in a box on the cartridge label after each cleaning. After the final use, discard the cleaning tape cartridge. Figure 3-5 shows the CleaningTape III cartridge. Figure 3-5 CleaningTape III Cartridge Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3-21 Use Table 3-12 to determine when to use the cleaning cartridge. Table 3-12 When to Use the Cleaning Cartridge ------------------------------------------------------------ If... It means... And you should... ------------------------------------------------------------ The Use Cleaning Tape indicator turns on (Figure 3-1) The drive head needs cleaning or the tape is bad (see 3rd item in table). Use the cleaning cartridge. Follow the instructions in Section 3.7 for loading a cartridge into the drive. When cleaning is complete, the beeper sounds for you to remove the cleaning cartridge. A particular cartridge causes the Use Cleaning Tape indicator to turn on frequently Back up this data on another cartridge, and then discard the old cartridge. A damaged cartridge may cause unnecessary use of the cleaning cartridge. The Use Cleaning Tape indicator turns on after you clean the drive head and reload your data cartridge Your data cartridge may be causing the problem. Try another data cartridge. The Use Cleaning Tape indicator is on after you load the cleaning cartridge Cleaning has not been done and the cartridge is expired. Replace the cleaning cartridge. ------------------------------------------------------------ 3-22 Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3.11 Standard OpenVMS Tape Commands There are certain guidelines you should follow to use the TZ86 and TZ87 subsystem effectively with your host application. To maximize the subsystem's efficiency, you must use certain qualifiers with the MOUNT and BACKUP commands. ------------------------------------------------------------ Note ------------------------------------------------------------ Not all OpenVMS tape qualifiers are functional with tape devices connected to the HSD05. ------------------------------------------------------------ For efficient operation of the TZ86 and TZ87 subsystems: · Choose a large block size when mounting a tape; 65534 is recommended. · Do not use the COPY command to save more than 9999 files onto the tape. ------------------------------------------------------------ Notes ------------------------------------------------------------ Using the COPY command to move multiple files may not achieve optimum performance. Check with your system manager or your OpenVMS documentation for more information. The HSD05 DSSI-to-SCSI bus adapter always operates cache-capable tape devices in cached mode, regardless of the setting of the MOUNT /CACHE=TAPE command. ------------------------------------------------------------ The TZ86 and TZ87 cartridge tape subsystems use the standard magnetic tape commands that can be invoked under the OpenVMS operating system, version 5.4-2 or later. The OpenVMS commands used to operate the TZ86 and TZ87 are: · ALLOCATE · INITIALIZE · MOUNT · BACKUP · COPY · DISMOUNT · DEALLOCATE Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3-23 3.11.1 Using the ALLOCATE Command The ALLOCATE command provides exclusive access to a device and optionally establishes a logical name for that device. Once you have allocated a device, other users cannot access that device until you explicitly DEALLOCATE it, or until you log out. Use the following format to allocate the TZ86 or TZ87 subsystem: $ ALLOCATE device_name: [logical name] For example, to allocate the TZ86 or TZ87 subsystem for your use and assign it the logical name TAPE1, do the following: $ ALLOCATE MUA0: TAPE1 3.11.2 Using the INITIALIZE Command ------------------------------------------------------------ CAUTION ------------------------------------------------------------ When a tape is initialized, any data already on the tape will be destroyed. ------------------------------------------------------------ Use the INITIALIZE command to specify the device name, and write a volume name to the magnetic tape volume loaded into the TZ86 or TZ87 tape drive. The tape must be write-enabled for the initializing operation. For the TZ86 and TZ87, use the following format: $ INITIALIZE device_name: [volume label] As an example, to initialize the device MUA0 and assign the volume name GMB001, type the following for the TZ86 and TZ87: $ INITIALIZE MUA0: GMB001 For the initialization to succeed, the cartridge must not have been mounted (with the MOUNT command). For detailed information regarding volume names and magnetic tape operations, see the Guide to VAX/VMS Disk and Magnetic Tape Operations (AA-M539A-TE). 3-24 Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3.11.3 Using the MOUNT Command The MOUNT command lets you make a magnetic tape volume available for processing. It loads the tape with the protection set according to the write-protect switch on the cartridge. It can determine the maximum block size on the TZ87. Use the following format to mount a tape on the TZ86 and TZ87 subsystem for use with the BACKUP utility: $ MOUNT/FOREIGN/BLOCKSIZE=65534 device_name: [volume label] [logical name] As an example, to make the device MUA0 available for processing on the TZ86 or TZ87 and assign it the logical name TAPE1, type the following: $ MOUNT/FOREIGN/BLOCKSIZE=65534 MUA0: GMB001 TAPE1 The screen displays a message: %MOUNT-I-MOUNTED, GMB001 mounted on MUA0: You must use the /FOREIGN qualifier when you are performing BACKUP commands. Do not use it when you are performing COPY commands. 3.11.4 Using the BACKUP Command The BACKUP command provides protection against file volume corruption by creating backup copies. Use the following format to back up a file on the TZ86 and TZ87: $ BACKUP/BLOCK=65534/ignore=(label) source:*.* tape:file.name You can also back up lists of files and entire volumes. See your system manuals before deciding on qualifiers for use with the BACKUP command. For detailed information about BACKUP and other OpenVMS tape commands, see the VAX/VMS Backup Utility Reference Manual (AA-Z407B-TE). Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3-25 3.11.5 Using the COPY Command Use the COPY command, with the TZ86 and TZ87 subsystem, to copy files from tape. In the following example, the MOUNT command requests that the volume labeled GMB001 be mounted on the drive at MUA0 and assigns the logical name TAPE1. The COPY command uses the logical name TAPE1 for the input file specification. All files on MUA0 are copied to the current default disk and directory. The files keep their original file names and file types. Use the following format on the TZ86 and TZ87: $ MOUNT/BLOCKSIZE=65534 MUA0: GMB001 TAPE1: $ COPY TAPE1:*.* *.* ------------------------------------------------------------ Notes ------------------------------------------------------------ Using the COPY command to move multiple files may not achieve optimum performance. Check with your system manager or your OpenVMS documentation for more information. The HSD05 DSSI-to-SCSI bus adapter always operates cache-capable tape devices in cached mode, regardless of the setting of the MOUNT /CACHE=TAPE command. ------------------------------------------------------------ 3.11.6 Using the DISMOUNT Command The DISMOUNT command cancels the previous MOUNT command, makes the unit unavailable for processing, and unloads the tape. Use the following format for the TZ86 and TZ87: $ DISMOUNT logical_name or device_name: 3.11.7 Using the DEALLOCATE Command The DEALLOCATE command cancels the previous ALLOCATE command and makes the unit available for other users. The following is an example of the command: $ DEALLOCATE MUA0: or TAPE1 3-26 Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3.12 Solving Problems The following sections describe what to do if you have drive or tape problems. 3.12.1 Common TZ86/TZ87 Errors You can avoid some errors by following these guidelines: · Use the correct cartridge type. See Section 3.5.3. · Care for your cartridges according to the guidelines in Section 3.9. · Make sure the cartridge leader and the drive leader are in their correct positions. See Section 3.12.2 and Section 3.12.3. · Unload the cartridge before powering down the system. If an error does occur during subsystem operation, you may be able to correct the error yourself. Factors influencing errors include: · Defective media · Dirty drive head · Operator or user errors · Incorrect backup commands Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3-27 Use Table 3-13 to interpret error symptoms, determine their causes, and take corrective action. Table 3-13 TZ86 and TZ87 Error Conditions ------------------------------------------------------------ Symptom Probable Cause Possible Correction ------------------------------------------------------------ Failure to mount or read /write with new or used cartridge Bad cartridge Retry with another cartridge.

Green Operate Handle light is on and tape does not move (yellow Tape in Use light stays on, does not blink) Cartridge load error Inspect the cartridge for a mispositioned leader (see Section 3.12.2). Replace the cartridge if its leader is mispositioned. Inspect the drive for a damaged, misplaced, or unhooked leader (see Section 3.12.3). Call Digital services if the drive leader is not in the correct location. All top front panel lights on the TZ86 or TZ87, and all bottom front panel lights on the TZ87 are blinking Drive failed self-test or detected a hard error during operation Try to clear the error by pressing the Unload button or turn power off and then on again. If the error does not clear (the tape does not rewind and unload and the lights blink), you have a hardware failure. Call Digital services. ------------------------------------------------------------ 3-28 Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3.12.2 Checking the Cartridge Leader Before you use a tape cartridge, be sure the tape leader is in the same position as the one shown in Figure 3-6. Lift the door lock with your thumb and open the small door to expose the leader. ------------------------------------------------------------ CAUTIONS ------------------------------------------------------------ Do not touch the exposed magnetic tape. If the tape leader is not in the correct position, do not try to fix it. Throw it away and use another cartridge instead. ------------------------------------------------------------ Figure 3-6 shows the correct position of the cartridge leader. Figure 3-6 CompacTape III Cartridge Leader Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3-29 3.12.3 Checking the Drive Leader To examine the drive takeup leader, open the cartridge receiver door on the front of the drive. Look inside to see that the drive leader is connected to the buckling link hook. The hook should be engaged in the leader slot (Figure 3-7). If the leader is unhooked, misplaced, or damaged, call Digital services. Do not try to fix the leader. Figure 3-7 shows the location of the leader inside the drive.

The dual device RRD43/TLZ07 can be installed only in the removable-media (right-most) option slot in the VAX 4000 system. Figure 4-1 shows the dual device RRD43/TLZ07 front panel and bezel. The RRD43 compact disc drive and the TLZ07 digital audio tape (DAT) cassette tape drive can also be installed separately. An RRD43-JA/JF disc drive installed separately utilizes different mounting brackets than the dual device ISE which allows it to be installed in any storage option slot. A TLZ07-JA/JF tape drive installed separately utilizes the same mounting brackets as the dual device ISE and can only be installed in the removable-media (right-most) option slot. The operating procedures are the same, whether installed as a dual device or separately. The RRD43 compact disc drive is a read-only device that can read information from industry standard 600 MB compact discs. The compact disc is inserted directly into the drive. The single ISE RRD43 compact disc drive can be installed in any storage option slot. ------------------------------------------------------------ Note ------------------------------------------------------------ If the single ISE RRD43 is installed in the removable-media (right-most) option slot in the VAX 4000 system, a small filler panel (PN 70-27414-01) is used to fill the remaining space. ------------------------------------------------------------ Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4-1 The TLZ07 digital audio tape (DAT) cassette tape drive provides a high capacity, off-line data storage.

Turn ON the VAX 4000 system power source. 2. Observe that, with no cassette in the drive, the Cassette and Write-Protect indicators light for approximately 1 to 5 seconds and then extinguish. With a cassette in the drive, the Cassette indicator continues flashing (approximately 20 seconds) until the cassette is loaded. 3. After successful completion of the power-on self-test, the Cassette and Write-Protect indicators turn off. ------------------------------------------------------------ NOTE ------------------------------------------------------------ If a tape is loaded, the Cassette indicator stays on and the Write-Protect indicator displays the write-protect status of the cassette. ------------------------------------------------------------ 4. If the Write-Protect indicator flashes amber and the drive indicator flashes green continuously for more than 30 seconds, then the power-on self-test failed. Attempt to clear the failure by re-executing the power-on self-test. (Power off and power on the drive.) Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4-15 4.5.3 Description of the TLZ07 Cassette Tape Depending on the type of 4 mm data cassette tape used, the TLZ07 tape drive can typically store: Tape Type (see NOTES 1 & 2.) No Compression Compression TLZ04-CA (60 m) 1.3 GB 2.6 GB TLZ06-CA (90 m) 2.0 GB 4.0 GB (see NOTE 3.) TLZ07-CA (120 m) 4.0 GB 8.0 GB (see NOTE 3.) ------------------------------------------------------------ NOTES ------------------------------------------------------------ 1. The TLZ07 is compatible with TLZ04 (60 m) cassette tapes in the noncompression mode only. 2. The TLZ07 is compatible with the TLZ06 using 60 m and 90 m tapes only. 3. The compression measurements are typical for a 2-to-1 data compression ratio, but the actual ratio is dependent on the data. ------------------------------------------------------------ The cassette tape includes a write-protect tab (Figure 4-7), which contrasts in color to the cassette tape body. Use a pen (NOT A PENCIL) to set the write-protect tab. · Slide the tab to the left to write-protect the tape. · Slide the tab to the right to write-enable the tape. ------------------------------------------------------------ NOTE ------------------------------------------------------------ The tab is not visible when the cassette tape is loaded in the TLZ07 drive. ------------------------------------------------------------ 4-16 Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive Figure 4-7 TLZ07 Cassette Tape Observe the following guidelines when setting the write-protect tab. · If you are using the tape to read or are copying from the tape, set the write- protect tab to write-protected. This disables writing to tape and ensures that data will not be accidentally overwritten. · If you are writing data, set the write-protect tab to write-enabled. · The write-protect tab position is shown on the front panel Write-Protect indicator. 4.5.4 Loading a Cassette Tape into the TLZ07 Drive Insert the TLZ07 cassette tape into the cassette slot on the TLZ07 front panel with the cassette's write-protect tab at the top, facing you. The green cassette LED flashes at 1 Hz and then goes to a steady green when the load sequence has completed. If the cassette tape that is being loaded has the write-protect tab in the write- protect position, the amber write-protect LED lights. If the cassette tape that is being loaded has the write-protect tab in the write-enable position, the amber write-protect LED stays off. Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4-17 4.5.5 Unloading a Cassette Tape from the TLZ07 Drive Press the unload button on the TLZ07 front panel to unload the TLZ07 cassette tape. The cassette tape unloads and is ejected from the cassette slot on the TLZ07 front panel. The green cassette LED flashes at 1 Hz while the tape is rewinding and then goes off when the unload sequence has completed. If the cassette tape that is being unloaded has the write-protect tab in the write- protect position, the amber write-protect LED goes off when the unload sequence has completed. If the cassette tape that is being unloaded has the write-protect tab in the write-enable position, the amber write-protect LED stays off during the entire unload sequence. 4.5.6 Proper Handling of Cassette Tapes To ensure optimal performance from the TLZ07 cassette tapes, observe the following guidelines when handling them. · Avoid placing the cassette tapes near sources of electromagnetic interference, such as terminals, video, or X-ray equipment. Emissions from such equipment can erase data on the tape. · Keep cassette tapes out of direct sunlight and away from heaters and other sources of heat. · Store cassette tapes (and cleaning cassette) where the room temperature is between 5°C and 32°C (40°F and 90°F). · Store cassette tapes in a dust-free environment where the relative humidity is 20% to 60%. ------------------------------------------------------------ WARNING ------------------------------------------------------------ Always place the tape label in the recessed area on the cassette. Never place one label on top of another label. ------------------------------------------------------------ 4-18 Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4.5.7 Cleaning the TLZ07 Tape Drive Heads This section explains how to clean the TLZ07 tape drive heads. The heads are the components that physically read and write data to and from the media (in this case, a cassette tape). Digital Equipment Corporation recommends that you perform the head cleaning procedure about every 2 weeks, or after every 50 hours of drive usage. Under normal conditions, it is not necessary to exceed this cleaning schedule. If a particular data cassette causes problems, try changing to another data cassette. ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Never attempt to clean the heads in a manner other than described in this procedure. Doing so voids the product warranty. ------------------------------------------------------------ To clean the heads, use the head cleaning cassette as follows: 1. Ensure that the drive is powered on. 2. Insert the head cleaning cassette (Part No. TLZ04-HA) into the drive. 3. With the head cleaning cassette inserted, the drive automatically executes head cleaning. The drive ejects the head cleaning cassette after approximately 30 seconds. 4. Locate the card enclosed with the head cleaning cassette. Place a check mark on the card every time you use the head cleaning cassette. Under normal conditions, the head cleaning cassette is used for about 25 cleanings. Additional cassettes are available from your Digital sales representative or DECdirect. If the head cleaning cassette has been overused, both the Cassette and the Write-Protect LEDs flash. Press the eject button to remove the cleaning cassette. No cleaning action will have occurred. Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4-19 4.5.8 Solving TLZ07 Problems Table 4-6 describes TLZ07 tape drive problems and possible solutions. Table 4-6 Problem Solving ------------------------------------------------------------ Symptom Probable Cause Possible Solution ------------------------------------------------------------ Unable to back up or copy data to cassette tape. Cassette write-protected. Set write-protect tab on cassette to write-enabled. No cassette tape in drive. Insert cassette tape. Write-Protect LED flashes amber. Excessive tape errors. Perform head cleaning procedure (see Section 4.5.7). If error repeats, try another cassette tape. Both LEDs flash rapidly, in unison. Dirty heads or bad media. Eject cassette tape. Perform head cleaning procedure (see Section 4.5.7). If error repeats, try another cassette tape. Drive error, possibly a hard failure. Eject cassette tape. Power off and power on the drive. If error repeats, call Digital services. After applying power, nothing happens. All indicators are off. Drive not receiving power. Remove the drive from the VAX 4000 and check power cable connections to the drive. Reseat the drive and apply power again. If the drive is still not receiving power, call Digital services. Unit not available to system. Bus node ID plug set to incorrect address. Check bus node ID plug. Faulty or improper cable connection. Remove the drive from the VAX 4000 and check all cable connections to the drive and front panel. Reseat the drive and apply power again. If the unit is still not available to the system, call Digital services. ------------------------------------------------------------ The VAX 4000 system has system-based diagnostics that can be used to test the TLZ07 tape drive. The HSD05 also has onboard utilities that can be used to test the TLZ07 tape drive (see Section 1.5.4.3). System-based diagnostics are usually referred to as console-based diagnostics, self-tests, or system exercisers. Refer to your system documentation for information about these diagnostics. 4-20 Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4.6 Standard OpenVMS TLZ07 Tape Commands There are certain guidelines you should follow to use the TLZ07 subsystem effectively with your host application. To maximize the subsystem's efficiency, you must use certain qualifiers with the MOUNT and BACKUP commands. ------------------------------------------------------------ Note ------------------------------------------------------------ Not all OpenVMS tape qualifiers are functional with tape devices connected to the HSD05. ------------------------------------------------------------ For efficient operation of the TLZ07 subsystem: · Choose a large block size when mounting a tape; 65534 is recommended. · Do not use the COPY command to save more than 9999 files onto the tape. ------------------------------------------------------------ Notes ------------------------------------------------------------ Using the COPY command to move multiple files may not achieve optimum performance. Check with your system manager or your OpenVMS documentation for more information. The HSD05 DSSI-to-SCSI bus adapter always operates cache-capable tape devices in cached mode, regardless of the setting of the MOUNT /CACHE=TAPE command. ------------------------------------------------------------ The TLZ07 cassette tape subsystem uses the standard magnetic tape commands that can be invoked under the OpenVMS operating system, Version 5.4-2 or later. The OpenVMS commands used to operate the TLZ07 are: · ALLOCATE · INITIALIZE · MOUNT · BACKUP · COPY · DISMOUNT · DEALLOCATE Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4-21 4.6.1 Using the ALLOCATE Command The ALLOCATE command provides exclusive access to a device and optionally establishes a logical name for that device. Once you have allocated a device, other users cannot access that device until you explicitly DEALLOCATE it, or until you log out. Use the following format to allocate the TLZ07 subsystem: $ ALLOCATE device_name: [logical name] For example, to allocate the TLZ07 subsystem for your use and assign it the logical name TAPE1, do the following: $ ALLOCATE MUA0: TAPE1 4.6.2 Using the INITIALIZE Command ------------------------------------------------------------ CAUTION ------------------------------------------------------------ When a tape is initialized, any data already on the tape will be destroyed. ------------------------------------------------------------ Use the INITIALIZE command to specify the device name, and write a volume name to the magnetic tape volume loaded into the TLZ07 tape drive. The tape must be write-enabled for the initializing operation. For the TLZ07, use the following format: $ INITIALIZE device_name: [volume label] As an example, to initialize the device MUA0 and assign the volume name GMB001, type the following for the TLZ07: $ INITIALIZE MUA0: GMB001 For the initialization to succeed, the cassette must not have been mounted (with the MOUNT command). For detailed information regarding volume names and magnetic tape operations, see the Guide to VAX/VMS Disk and Magnetic Tape Operations (AA-M539A-TE). 4-22 Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4.6.3 Using the MOUNT Command The MOUNT command lets you make a magnetic tape volume available for processing. It loads the tape with the protection set according to the write-protect switch on the cassette. It can determine the maximum block size on the TLZ07. Use the following format to mount a tape on the TLZ07 subsystem for use with the BACKUP utility: $ MOUNT/FOREIGN/BLOCKSIZE=65534 device_name: [volume label] [logical name] As an example, to make the device MUA0 available for processing on the TLZ07 and assign it the logical name TAPE1, type the following: $ MOUNT/FOREIGN/BLOCKSIZE=65534 MUA0: GMB001 TAPE1 The screen displays a message: %MOUNT-I-MOUNTED, GMB001 mounted on MUA0: You must use the /FOREIGN qualifier when you are performing BACKUP commands. Do not use it when you are performing COPY commands. 4.6.4 Using the BACKUP Command The BACKUP command provides protection against file volume corruption by creating backup copies. Use the following format to back up a file on the TLZ07: $ BACKUP/BLOCK=65534/ignore=(label) source:*.* tape:file.name You can also back up lists of files and entire volumes. See your system manuals before deciding on qualifiers for use with the BACKUP command. For detailed information about BACKUP and other OpenVMS tape commands, see the VAX/VMS Backup Utility Reference Manual (AA-Z407B-TE). Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4-23 4.6.5 Using the COPY Command Use the COPY command, with the TLZ07 subsystem, to copy files from tape. In the following example, the MOUNT command requests that the volume labeled GMB001 be mounted on the drive at MUA0 and assigns the logical name TAPE1. The COPY command uses the logical name TAPE1 for the input file specification. All files on MUA0 are copied to the current default disk and directory. The files keep their original file names and file types. Use the following format on the TLZ07: $ MOUNT/BLOCKSIZE=65534 MUA0: GMB001 TAPE1: $ COPY TAPE1:*.* *.* ------------------------------------------------------------ Notes ------------------------------------------------------------ Using the COPY command to move multiple files may not achieve optimum performance. Check with your system manager or your OpenVMS documentation for more information. The HSD05 DSSI-to-SCSI bus adapter always operates cache-capable tape devices in cached mode, regardless of the setting of the MOUNT /CACHE=TAPE command. ------------------------------------------------------------ 4.6.6 Using the DISMOUNT Command The DISMOUNT command cancels the previous MOUNT command, makes the unit unavailable for processing, and unloads the tape. Use the following format for the TLZ07: $ DISMOUNT logical_name or device_name: 4.6.7 Using the DEALLOCATE Command The DEALLOCATE command cancels the previous ALLOCATE command and makes the unit available for other users. The following is an example of the command: $ DEALLOCATE MUA0: or TAPE1 4-24 Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4.6.8 OpenVMS TLZ07 Compression and Noncompression Modes The default mode for the TLZ07 tape drive is noncompression mode. To use the TLZ07 tape drive in compression mode, when installed on an HSD05, use the /DENSITY= modifier. To select the noncompressed density, use the /DENSITY=1600 modifier; to select the compressed density, use the /DENSITY=6250 modifier. The selected density will be displayed in the SHOW DEVICE/FULL display. For initializing a tape on the TLZ07 in compression mode, use the following format: $ INITIALIZE/DENSITY=6250 device_name: [volume label] As an example, to initialize the device MUA0 in compression mode and assign the volume name OMEGA, type the following for the TLZ07: $ INITIALIZE/DENSITY=6250 MUA0: OMEGA Operating the RRD43 CD-ROM and TLZ07 DAT Tape Drive 4-25
