Each disk ISE within an SF-series enclosure is independently controlled from the OCP on the front of the enclosure. A power supply in the enclosure provides the dc power for all disk ISEs installed in the enclosure. A blower fan provides air flow for cooling. The SF3x storage enclosure holds up to twelve RF3x series ISEs (Figure 1-3). There are six slots in the front of the enclosure and six slots in the rear. Disk ISEs installed in these slots plug directly into a backplane, which is cabled to a connector tray on the top rear of the storage enclosure. The SF3x enclosure can be configured in through-bus mode or split-bus mode. In through-bus mode, the six ISEs in the front of the SF3x enclosure are connected to a single DSSI bus, and the six ISEs in the rear of the SF3x enclosure are connected to a second DSSI bus. In split-bus mode, each end of the enclosure (front and rear) is further divided into left-side ISEs and right-side ISEs, each connected to a separate DSSI bus. Thus, in split-bus mode there are four DSSI buses, each with three drives connected to it. The SF7x series storage enclosure holds either two or four RF7x series ISEs (Figure 1-4). The ISEs in the SF7x storage enclosure can also be configured in split-bus or through-bus mode. In through-bus mode, all four disk ISEs are connected to a single DSSI bus. In split-bus mode, the left-side ISEs are connected to one DSSI bus, while the right-side ISEs are connected to a second DSSI bus. The SF-series storage enclosures have the following features: · Both can operate in either through-bus or split-bus mode. · Each disk ISE has its own set of switches and indicators on the OCP. · The enclosure power supply provides operating power to all disk ISEs and other subassemblies in the enclosure. · The drive dc power switches for the disk ISEs are on the front panel of the storage enclosure.

The power-on self-test, or POST, is initializing the subsystem. When POST completes successfully, all OCP indicators, including the Magazine Fault and Loader Fault indicators, turn off--except for Power On. ------------------------------------------------------------ Note ------------------------------------------------------------ If the Magazine Fault or Loader Fault indicator remains on, POST has detected an error. See Chapter 4 of the TF857 Series Magazine Tape Subsystem Owner 's Manual for error conditions. ------------------------------------------------------------ The elevator scans the magazine to determine which slots contain cartridges. If the subsystem has a magazine with a cartridge in slot zero, and no cartridge is in the drive, these indicators should be on: Power On Eject Load/Unload Slot Select Slot 0 TF8x7 Magazine Tape Subsystem 2-1 TF8x7 Magazine Tape Subsystem 2.2 Mode Select Key 2.2 Mode Select Key The Mode Select key (Figure 2-1) can lock the loader transfer assembly into the enclosure, as well as lock the receiver closed. It has four modes: OCP Disabled, Automatic, Manual, and Service. The OCP Disabled, Automatic, and Manual modes are for operational use; the Service mode is for head cleaning and servicing procedures. 2.2.1 Operating Modes Use the following modes for operational use: · OCP Disabled mode--When the magazine is inserted into the receiver and the receiver is closed, the loader transfer assembly scans the magazine. The first cartridge in the magazine automatically loads into the drive. Operations stop if you are copying data to tape and either the storage capacity of the last tape cartridge is exceeded, or no tape cartridge is in the next sequential slot in the magazine. To lock the TF8x7 subsystem into the enclosure and lock the receiver, set the Mode Select key to OCP Disabled mode. The OCP pushbuttons are disabled. · Automatic mode--This mode is the default, or normal, mode of the TF8x7 subsystem. It automatically loads and unloads cartridges as necessary during backup procedures. Operations stop if you are copying data to tape and either the storage capacity of the last tape cartridge is exceeded, or no tape cartridge is in the next sequential slot in the magazine. To lock the TF8x7 subsystem into its normal operating position in the enclosure but leave the receiver unlocked, set the Mode Select key to Automatic mode. The receiver can be opened; all OCP pushbuttons are enabled. · Manual mode--Automatic loading and unloading of cartridges does not occur in this mode; rather, you must press the Load/Unload button to move each cartridge. This mode is most useful for, but not restricted to, copying specific files to or from tape. To lock the TF8x7 subsystem into the enclosure, set the Mode Select key to Manual mode. The receiver is unlocked and can be opened; all OCP pushbuttons are on. ------------------------------------------------------------ Note ------------------------------------------------------------ During Manual mode, the cartridge returns to the magazine, but the current Slot Select indicator does not advance forward to the next available cartridge. ------------------------------------------------------------ 2-2 TF8x7 Magazine Tape Subsystem TF8x7 Magazine Tape Subsystem 2.2 Mode Select Key Figure 2-1 TF8x7 Operator Control Panel TF8x7 Magazine Tape Subsystem 2-3 TF8x7 Magazine Tape Subsystem 2.2 Mode Select Key 2.2.2 Service Mode Service mode is for performing head cleaning by manually loading the CleaningTape III and for performing servicing procedures. See Chapter 5 of the TF857 Series Magazine Tape Subsystem Owner 's Manual for information on head cleaning. To unlock the TF8x7 subsystem from its enclosure and remove it from its normal operating position, set the Mode Select key to Service mode. The receiver is unlocked and can be opened. 2.3 Operator Control Panel The TF8x7 operator control panel (OCP) has 3 OCP pushbuttons and 16 indicators that are used with the Mode Select key (Table 2-1).

The two-ISE variant is referred to as -HE, and the four-ISE variant is referred to as -JE. SF7x series storage enclosures residing in SF400 DECarray cabinets can be connected to a single system or to multiple systems in a DSSI VAXcluster system configuration. Either of these variants operate in one of two bus modes. These modes are called through-bus and split-bus, and are described in the sections that follow. 3.1.1 Through-Bus Mode In through-bus mode, all four disk ISEs in the storage enclosure operate on or are part of the same DSSI bus. The DSSI bus enters the enclosure from the rear, at the rightmost DSSI connector. The DSSI bus is then connected to the left rear disk ISE (facing the front of the enclosure), then the left front disk ISE, the right front disk ISE, then the right rear disk ISE, and finally out the leftmost (facing rear again) DSSI connector. At this point, the DSSI bus is either terminated (with a DSSI terminator, part number 12-31281-01) or connected to another storage enclosure (operating in split-bus mode in a single system or stripe set configuration).

Figure 3-1 Through-Bus Mode The -HE variant operates in through-bus mode, in a similar fashion, but only the rear two disk ISEs are used. An SF7x-UK upgrade kit consisting of two RF7x disk ISEs can be added at any time. 3.1.2 Split-Bus Mode In split-bus mode, two disk ISEs in the storage enclosure operate on or are part of two separate DSSI buses. The DSSI bus enters the enclosure from the rear, at the leftmost or rightmost DSSI connector. The DSSI bus for the left half of the enclosure is connected to the left rear disk ISE (facing the front of the enclosure), then the left front disk ISE, and finally terminated at the transition termination module (TTM) for the left half of the enclosure. The DSSI bus for the right half of the enclosure is connected to the right rear disk ISE (facing the front of the enclosure), then the right front disk ISE, and finally terminated at the TTM for the right half of the enclosure. Figure 3-2 shows a typical VAX 6000/7000 system and DECarray DSSI bus, with DSSI ID numbers. 3-2 SF7x Series Storage Enclosure Operation SF7x Series Storage Enclosure Operation 3.1 Storage Enclosure Configurations ------------------------------------------------------------ NOTE ------------------------------------------------------------ Split-bus mode is not supported in DSSI VAXcluster system configurations. ------------------------------------------------------------ Figure 3-2 Split-Bus Mode The -HE variant operates in split-bus mode, in a similar fashion, but only the rear two disk ISEs are used. An SF7x-UK upgrade kit consisting of two RF7x disk ISEs can be added to an -HE at any time. 3.2 Front Panel Controls, Labels, and Indicators Figure 3-3 shows a front view of the storage enclosure.

They are arranged on two DSSI buses, one for the front six ISEs and one for the rear six ISEs. These can be further divided into four DSSI buses, each with three ISEs by configuring the storage enclosure in split-bus mode, as described in the next section. Ease ISE slides into a slot in the enclosure, where it plugs directly into a backplane. There is one backplane for the front six ISEs and one backplane for the rear six ISEs. The location of an ISE within the backplane determines its DSSI node ID, as follows: DSSI node ID 1--Upper left slot DSSI node ID 2--Upper right slot DSSI node ID 3--Middle left slot DSSI node ID 4--Middle right slot DSSI node ID 5--Lower left slot DSSI node ID 6--Lower right slot SF3x Series Storage Enclosure 4-1 SF3x Series Storage Enclosure 4.1 SF3x Overview SF3x series storage enclosures can be connected to a single system, or they can be connected to multiple systems in a DSSI VAXcluster configuration. It can operate in one of two bus modes, through-bus or split-bus mode. These nodes are described in the sections that follow. 4.1.1 Through-Bus Mode In through-bus mode, all six ISEs in each half of the storage enclosure are connected to the same DSSI bus. The DSSI bus enters through the left DSSI connector on the top of the backplane, connects to ISEs 1, 3, and 5 on the left side of the enclosure, then goes through ISEs 6, 4, and 2, and finally out the right DSSI connector (Figure 4-1). At this point, the DSSI bus is either terminated (with a DSSI terminator, part number 12-31281-01), connected to a magazine tape ISE, or connected to the DECarray I/O panel. 4-2 SF3x Series Storage Enclosure SF3x Series Storage Enclosure 4.1 SF3x Overview Figure 4-1 Through-Bus Mode SF3x Series Storage Enclosure 4-3 SF3x Series Storage Enclosure 4.1 SF3x Overview 4.1.2 Split-Bus Mode Each set of six ISEs (front and rear) can be further separated by putting the left ISEs (DSSI nodes 1, 3, and 5) and right ISEs (DSSI nodes 2, 4, and 6) on separate DSSI buses. This configuration leaves each enclosure with four distinct DSSI buses, each with three disk ISEs (Figure 4-2). This configuration is most often used when the DECarray is configured in stripe sets.

The KFQSA module is a Q-bus-to-DSSI bus adapter. The KFMSA module is an XMI-to-DSSI bus adapter. allocation class A numerical value assigned to the ISE to indicate which system(s) on a cluster it will be served by. block The smallest data unit addressable on a disk, also called a sector. In DSSI ISEs, a block contains 512 bytes of customer data, EDC, ECC, flags, and the block's address header. DECarray A storage array that houses up to six storage enclosures and up to two magazine tapes (such as the TF857 storage array). device name A unique name given to each device by the VMS operating system. The device name generally includes either the allocation class and MSCP unit number assigned to the device (if the allocation class is not zero), or the node name and MSCP unit number (if the allocation class is zero). DRVTST A local program resident on the ISE. It is a comprehensive hardware test used to verify ISE operation. Glossary-1 DSSI Digital Storage System Interconnect. A DSA-based storage interconnect used by the KFMSA adapter and the RF- and TF-series integrated storage elements to transfer data and to communicate with each other. DSSI VAXcluster system Storage configuration where DSSI ISEs are shared between two DSSI adapters and systems. DUP Diagnostic and utility protocol. A SYSAP-level protocol by which a computer directs a storage device controller to run internal diagnostics or utility functions. DUP is implemented as a class driver on the system side and a corresponding class server on the storage controller side. EEPROM Electrically-erasable programmable read only memory. Used by the KFMSA adapter to store configuration, manufacturing, and error information in a nonvolatile location. embedded adapter An adapter that connects one or more device controllers to the system bus (such as a VAX 4000 system) and hides many of the system bus requirements from the controller. Refer to the system documentation for further information. ISE Integrated storage element. All DSSI storage devices are ISEs. KFMSA XMI bus to DSSI bus adapter. KFQSA Q-bus to DSSI bus adapter. magazine tape A DSSI tape ISE with tape loader, such as a TF857 storage array. MDM MicroVAX Diagnostic Monitor. Diagnostic tool for isolating problems in systems running MicroVMS software. Glossary-2 MSCP Mass Storage Control Protocol. An application layer protocol used by the system to perform disk I/O operations and I/O control functions. node name A six-character (maximum) value that is assigned to each DSSI ISE. The node name of each ISE must be unique across the system topology. OCP Operator control panel. An enclosure interface that allows remote control of DSSI node ID selection and ISE operating status. PARAMS A local program resident on the ISE. PARAMS is used to view and modify current device parameter settings on an ISE. Q-bus The system bus for the MicroVAX II, MicroVAX/VAXserver 3xxx, and VAX 4000 series systems. RF73 A 2-GB formatted capacity DSSI disk ISE. RLL Run length limited. The format used in the DSSI ISE to record data. SF7x A DSSI storage enclosure that houses either two or four RF-series disk ISEs. single system Storage configuration where DSSI ISEs are connected to only one DSSI adapter and system. split-bus A mode of operation where the ISEs in the right side of a storage enclosure are connected to a different DSSI bus than those on the left side. In this mode, the DSSI buses are terminated by the TTM. Glossary-3 stripe set A set of disk drives operating in concert as a single virtual disk to provide increased I/O performance. In a DSSI bus application, all SF7x storage enclosures are in split-bus mode and each half of each enclosure is connected to its own dedicated DSSI adapter port. through-bus A mode of operation where all the ISEs in a storage enclosure are connected to the same DSSI bus. In this mode, the DSSI bus is terminated using an external terminator. TMSCP Tape Mass Storage Control Protocol. Application layer protocol that is used by the system to perform tape I/O operations and I/O control functions. TTM Transition termination module. A PC board that connects the storage enclosure OCP and RF-series disk ISE, and also provides DSSI bus termination when in split-bus mode. unit number Also called the MSCP/TMSCP unit number. Default value is the ISE's DSSI node ID. A unique value can be selected using PARAMS. VAX Diagnostic Supervisor A diagnostic environment that allows access to DSSI tests and programs in VAX 6000 and 9000 series systems. virtual circuit A logical point-to-point link between nodes. XMI Extended Memory Interconnect. The system bus for the VAX 6000 and 9000 series systems.
