The Tx85 comes embedded in a system enclosure or in a tabletop enclosure with its own power supply. The Tx85 is available in these variations:  TF85, for systems using the DSSI bus  TZ85, for systems using the SCSI bus ------------------------------------------------------------ Basic Components The Tx85 subsystem consists of the following basic components: ------------------------------------------------------------ TF85 Subsystem TZ85 Subsystem ------------------------------------------------------------ TK85 tape drive TK85 tape drive DSSI controller module SCSI controller module ------------------------------------------------------------ The TK85 drive is a streaming tape drive that can store up to 2.6 gigabytes of data on a CompacTape III cartridge. The Tx85 subsystem connects to the computer system through the controller module, which is responsible for initiating commands to the TK85 drive. ------------------------------------------------------------ Continued on next page 1-2 Tx85 Cartridge Tape Subsystem, Continued ------------------------------------------------------------ Basic Components (continued) Depending on your host system configuration, the SCSI controller module comes as one of the following two options: ------------------------------------------------------------ This controller option. . . For this SCSI cable. . . ------------------------------------------------------------ Single-ended 6-meter (19-foot) single-ended cable (ANSI SCSI standard) Differential Longer differential SCSI cables with better noise immunity ------------------------------------------------------------ ------------------------------------------------------------ Performance Consideration The VMS backup performance rate of your Tx85 subsystem can depend on your system processor. For example:  Connecting directly to an embedded bus adapter on such systems as the VAX 4000, VAX 6000, or InfoServer 150 (TZ85 only) provides optimum performance.  Connecting to a MicroVAX/VAXserver 3xxx (Q-bus) system can reduce the rate of performance but does not limit the high capacity of data storage that your Tx85 has. ------------------------------------------------------------ Required Load Device The TF85, when connected to a KFQSA adapter installed in a MicroVAX II or MicroVAX/VAXserver 3xxx system, does not support booting of VMS or MicroVAX Diagnostic Monitor (MDM) software. An additional load device is needed to boot this software. ------------------------------------------------------------ Continued on next page 1-3 Tx85 Cartridge Tape Subsystem, Continued ------------------------------------------------------------ Decals The Tx85 subsystem ships with decals including the appropriate language of the country to which the subsystem has been shipped. The decals adhere to the cartridge insert /release handle and the indicator panel (see Tx85 Front Panel). The tabletop TZ85 also has a decal for the switchpack on the rear panel. ------------------------------------------------------------ Tx85 Front Panel The following diagram shows the front panel of the Tx85 cartridge tape subsystem: ------------------------------------------------------------ 1-4 Data Tape ------------------------------------------------------------ CompacTape III Description The CompacTape III is a 4- 1 = 8-inch square, dark gray, plastic cartridge containing 1200 feet of 1= 2-inch magnetic, metal particle (MP) tape. ------------------------------------------------------------ Cartridge Packaging Your CompacTape III is supplied with a:  Set of slide-in labels for cartridges  Cartridge handling information sheet ------------------------------------------------------------ Reading and Writing Data The TK85 drive writes 24 pairs of tracks--48 tracks in all--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. ------------------------------------------------------------ Write-Protecting Data The CompacTape III cartridge has a write-protect switch to prevent accidental erasure of data (see CompacTape III Diagram). 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 data cannot be written to the tape. ------------------------------------------------------------ Continued on next page 1-5 Data Tape, Continued ------------------------------------------------------------ Write-Protecting Data (continued) On the right side of the write-protect switch is another symbol, an arrow over one line. The symbol indicates if the write- protect switch is moved to the right, data can be written to the tape. ------------------------------------------------------------ CompacTape III Diagram The following diagram shows the CompacTape III cartridge and its write-protect switch: ------------------------------------------------------------ 1-6 Cartridge Compatibility ------------------------------------------------------------ Read-Only Cartridges Older CompacTape cartridges can be loaded for read-only purposes into the TK85 tape drive. Any cartridges recorded by the TK50, TK70, or TZ30 tape drive can be read by the TK85 drive. ------------------------------------------------------------ Comparison of Read/Write Ability The following table shows cartridge compatibility with the TK85 drive: ------------------------------------------------------------ Cartridge Type Read/Write Ability in the TK85 Drive ------------------------------------------------------------ CompacTape (TK50/TZ30) Read-only CompacTape II (TK70) Read-only CompacTape III (TK85) Read/write ------------------------------------------------------------ ------------------------------------------------------------ 1-7 Cleaning Tape ------------------------------------------------------------ CleaningTape III Description The CleaningTape III is a 4 1 = 8-inch square, light yellow, plastic cartridge containing 1200 feet of 1= 2-inch, cleaning tape. See Chapter 2 for information on using the CleaningTape III. ------------------------------------------------------------ Cartridge Packaging Your CleaningTape III is supplied with a:  Slide-in label that has 20 boxes, each for marking a check after cartridge use (see Cartridge Expiration)  Cartridge handling information sheet ------------------------------------------------------------ Cartridge Expiration You can use the CleaningTape III cartridge approximately 20 times before it expires. The word expire does not pertain to an expiration date. Expire means no cleaning area is left on the tape. To record the number of uses, mark a check in one box on the cartridge label after each cleaning. After the final use, discard the cleaning tape cartridge. ------------------------------------------------------------ Continued on next page 1-8 Cleaning Tape, Continued ------------------------------------------------------------ CleaningTape III Diagram The following diagram shows the CleaningTape III: ------------------------------------------------------------ 1-9 Supplies ------------------------------------------------------------ Cartridges Provided One CompacTape III cartridge and one CleaningTape III cartridge ship with the Tx85 subsystem. ------------------------------------------------------------ How To Order You can order additional cartridges by contacting your Digital sales representative or by calling Digital's DECdirect ordering service at 1-800-DIGITAL.

When you hear the beep, the green light is on. ------------------------------------------------------------ Unload Button The Unload button rewinds the tape and unloads the tape from the drive back into the cartridge. The tape must be completely rewound and unloaded into the cartridge before you remove the cartridge from the drive. Depending on tape position, an unload operation may take from 10 seconds to 4 minutes. ------------------------------------------------------------ Cartridge Insert/Release Handle Operate the cartridge insert/release handle to load a cartridge or to eject a cartridge only when the Operate Handle indicator is on, and after the momentary beep sounds. The handle lifts to the open position and lowers to the closed position. See Loading a Cartridge and Unloading a Cartridge for the operating procedures. ------------------------------------------------------------ 2-5 Cartridge Write-Protect Switch ------------------------------------------------------------ Positioning the Switch Before loading the CompacTape III into the drive, position the write-protect switch on the front of the cartridge. The switch can move to the left so that the cartridge is write-protected, or to the right so that the cartridge is write-enabled (see Diagram of the Switch). ------------------------------------------------------------ Diagram of the Switch The following diagram shows the write-protect switch on the CompacTape III: ------------------------------------------------------------ Continued on next page 2-6 Cartridge Write-Protect Switch, Continued ------------------------------------------------------------ Data Protection The following table describes what happens to data protection when you move the write-protect switch: ------------------------------------------------------------ If you move the write-protect switch before loading the cartridge. . . Then. . . ------------------------------------------------------------ To the left on the cartridge, the tape is write-protected, with the orange indicator showing You cannot write data to the tape. To the right on the cartridge, the tape is write-enabled You can write data to the tape (if it is not software write-protected). ------------------------------------------------------------ If you move the write-protect switch during operation. . . Then. . . ------------------------------------------------------------ From the write-protected position to the write-enabled position The tape becomes write-enabled after a variable amount of time (on order of seconds). From the write-enabled position to the write-protected position The tape becomes write-protected after a variable amount of time (on order of seconds). ------------------------------------------------------------ ------------------------------------------------------------ 2-7 Loading a Cartridge ------------------------------------------------------------ Steps To Follow The directions for loading a cartridge into and unloading a cartridge from the drive are printed on the front of the drive. The following are more detailed steps for loading a cartridge (see Diagram of Cartridge Loading): 1. When the green light is on steadily, pull the cartridge insert /release handle open. 2. Insert the cartridge. 3. Push the cartridge into the drive. 4. Push the handle closed. The green light turns off and the yellow light blinks to show that the tape is loading. When the tape is at the beginning-of- tape (BOT) marker, the yellow indicator turns on steadily. The tape is now ready for use. ------------------------------------------------------------ Continued on next page 2-8 Loading a Cartridge, Continued ------------------------------------------------------------ Diagram of Cartridge Loading The following diagram shows how to load a cartridge into the drive: ------------------------------------------------------------ 2-9 Using a Cartridge ------------------------------------------------------------ Tape in Use Whenever the yellow light is on steadily, the tape is ready to use. When the tape is being read, written, or rewound, the yellow light blinks. ------------------------------------------------------------ Things To Note During Cartridge Use Use the following table to determine what is happening during cartridge use: ------------------------------------------------------------ If. . . Then. . . ------------------------------------------------------------ The yellow light is on steadily A cartridge is loaded, but the tape is not moving. This condition can mean that no application is communicating with the controller, or that the application is communicating but is not delivering commands for tape motion. The yellow light blinks irregularly A read or write is in progress. The yellow light blinks regularly The tape is loading, unloading, or rewinding. The green light turns on and the beeper sounds The tape is unloaded. All four lights blink An error has occurred during operation. See Chapter 3, Solving Problems. ------------------------------------------------------------ ------------------------------------------------------------ 2-10 Using the CleaningTape III ------------------------------------------------------------ When To Use If the Use Cleaning Tape indicator turns on (see Diagram of Indicators and Controls), the drive head needs cleaning or the tape is bad (see Problem Data Cartridge). Use the CleaningTape III. Follow the instructions in this chapter for loading a cartridge into the drive. When cleaning is complete, the beeper sounds for you to remove the CleaningTape III. If you use the CleaningTape III when the Use Cleaning Tape indicator is off, the CleaningTape III will load and clean the drive. ------------------------------------------------------------ Problem Data Cartridge If 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, and if the Use Cleaning Tape indicator turns on again, call Digital Services. ------------------------------------------------------------ Expired Cleaning Tape If the Use Cleaning Tape indicator is on after you load the CleaningTape III, then cleaning has not been done and the cartridge is expired. Replace the cleaning cartridge. The CleaningTape III expires after approximately 20 uses. ------------------------------------------------------------ 2-11 Unloading a Cartridge ------------------------------------------------------------ Steps To Follow Follow these steps to unload a cartridge from the drive (see Diagram of Cartridge Unloading): 1. Press the Unload button (or issue the appropriate system software command). 2. When the green 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 Cartridges must be removed from the drive before host system power is turned off. Failure to remove a cartridge can result in cartridge and drive damage. To prolong the life of your cartridge, return the cartridge to its plastic case when you remove the cartridge from the drive. ------------------------------------------------------------ Continued on next page 2-12 Unloading a Cartridge, Continued ------------------------------------------------------------ Diagram of Cartridge Unloading The following diagram shows how to unload a cartridge from the drive: ------------------------------------------------------------ 2-13 Preserving Cartridges ------------------------------------------------------------ Guidelines 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 72°F ± 7°F (22°C± 4°C).  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, and 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. ------------------------------------------------------------ 2-14 Chapter 3 Solving Problems In This Chapter ------------------------------------------------------------ Introduction This chapter describes what to do if you have drive or tape problems. ------------------------------------------------------------ Contents Chapter 3 describes the following topics: ------------------------------------------------------------ Topic Page ------------------------------------------------------------ Common Errors 3-2 Inspections 3-4 ------------------------------------------------------------ ------------------------------------------------------------ 3-1 Common Errors ------------------------------------------------------------ Avoiding Basic Problems You can avoid some errors by following these guidelines:  Use the correct cartridge type. See Cartridge Compatibility in Chapter 1.  Care for your cartridges according to the guidelines in Preserving Cartridges , Chapter 2.  Make sure the cartridge leader and the drive leader are in their correct positions. See Inspections in this chapter.  Unload the cartridge before powering down the system. ------------------------------------------------------------ Error Influences 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 See Finding Solutions in this chapter for information on detecting and correcting these errors. ------------------------------------------------------------ Continued on next page 3-2 Common Errors, Continued ------------------------------------------------------------ Finding Solutions Use the following table to interpret error symptoms, determine their causes, and take corrective action: ------------------------------------------------------------ Symptom Probable Cause Possible Correction ------------------------------------------------------------ Failure to mount or read/write with new or used cartridge Bad cartridge Dirty drive head Retry with another cartridge. Use CleaningTape III. VMS INITIALIZE command fails with parity error Tape calibration failed Try another cartridge. Green light is on and tape does not move (yellow light stays on, does not blink) Cartridge load error Inspect the cartridge for a mispositioned leader (see Diagram of Cartridge Leader in this chapter). Replace the cartridge if its leader is mispositioned. Inspect the drive for a damaged, misplaced, or unhooked leader (see Diagrams of Drive Leader in this chapter). Call Digital Services if the drive leader is not in the correct location. All four lights blinking Drive failed self- test or detected a hard error during operation Try to clear the error by pressing the Unload button. If the error does not clear (the tape does not rewind and unload and the four lights blink), you have a hardware failure. Call Digital Services. ------------------------------------------------------------ ------------------------------------------------------------ 3-3 Inspections ------------------------------------------------------------ Checking the Cartridge Leader Before you use a tape cartridge, be sure the tape leader is in the same position as the one in Diagram of Cartridge Leader. 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. Use another cartridge instead. ------------------------------------------------------------ Diagram of Cartridge Leader The following diagram shows the correct position of the cartridge leader: ------------------------------------------------------------ Continued on next page 3-4 Inspections, Continued ------------------------------------------------------------ Checking the Drive Leader Compare the leader inside your drive with those shown in Diagrams of Drive Leader. If the leader is unhooked, misplaced, or damaged, call Digital Services. Do not try to fix the leader. ------------------------------------------------------------ Diagrams of Drive Leader The following diagram shows the location of the leader inside the drive: ------------------------------------------------------------ Continued on next page 3-5 Inspections, Continued ------------------------------------------------------------ Diagrams of Drive Leader (continued) The following diagram shows the correct and incorrect locations of the drive leader: ------------------------------------------------------------ 3-6 Chapter 4 Running Local Programs on the TF85 Subsystem In This Chapter ------------------------------------------------------------ Introduction This chapter shows you how to use the following local programs that reside in read-only memory (ROM) on the TF85 subsystem:  PARAMS allows you to modify parameters for your TF85.  DIRECT provides a directory of available local programs.  HISTRY displays information about the TF85. ------------------------------------------------------------ Contents Chapter 4 includes the following topics: ------------------------------------------------------------ Topic Page ------------------------------------------------------------ Using the TF85 PARAMS Program 4-2 Using the TF85 DIRECT and HISTRY Utilities 4-10 ------------------------------------------------------------ ------------------------------------------------------------ 4-1 Using the TF85 PARAMS Program ------------------------------------------------------------ About PARAMS PARAMS can be executed while the tape is controlled by another application. PARAMS is used only to access and change controller parameters. When you execute PARAMS, communications between the host system and the TF85 subsystem are through the diagnostic utilities protocol (DUP). When you exit PARAMS, control is returned to the operating system. ------------------------------------------------------------ Starting PARAMS After defining a symbol node name to be the node name parameter for your drive, access PARAMS with the DCL command. The following example shows the sequence of commands to start PARAMS. These commands are for the VMS operating system, version 5.4 or later. $ SHOW CLUSTER View of Cluster from system ID 18582 node: DROVIM 7-OCT-1991 11:47:03 ----------------------------- | SYSTEMS |MEMBERS | |---------------------------| |NODE | SOFTWARE | STATUS | |-------|----------|--------| |DROVIM | VMS V5.3 | MEMBER | |GEAR | RFX V103 | | |LIBRY | RFX V103 | | |TF85 | TFX V002 | | |CANDY | VMS V5.3 | MEMBER | |BOLTS | VMS V5.3 | MEMBER | ----------------------------- $ SET HOST/DUP/SERVER=MSCP$DUP/TASK=PARAMS TF85 ------------------------------------------------------------ Continued on next page 4-2 Using the TF85 PARAMS Program, Continued ------------------------------------------------------------ Starting PARAMS (continued) Note that you can determine the node name by executing the SHOW CLUSTER command. Also note that, after TASK=, you append PARAMS to execute the PARAMS program. NOTE The node name is the name of the tape device. The node name is derived from the subsystem's serial number, unless you already reassigned the node name through PARAMS. A drive received from the factory has a unique drive serial number and, therefore, a unique node name. Once you invoke PARAMS through the SET HOST/DUP command, the screen displays the following prompt: PARAMS> The PARAMS> prompt indicates that you have accessed the PARAMS program. ------------------------------------------------------------ Unit Off-Line Message If, when using the SET HOST/DUP command, you receive the error message: Unit offline you might have forgotten to load the FYDRIVER program. (Loading FYDRIVER a second time will not cause any problem.) Load FYDRIVER as follows: $ MCR SYSGEN (to access SYSGEN) $ SYSGEN> LOAD FYDRIVER (to load FYDRIVER, prerequisite to using diagnostics) $ SYSGEN> CON FYA0/NOADAP (to configure FYDRIVER) $ SYSGEN> EXIT ------------------------------------------------------------ Continued on next page 4-3 Using the TF85 PARAMS Program, Continued ------------------------------------------------------------ Changing the Node Name You may want to change the default node name to something you can recognize more easily than the node name the system created. If you decide to change the node name, you should be aware of the following:  It is preferable to change the node name only once--when the device is first installed into your VMS system. Digital Services representatives know how to change the node name and avoid the error and additional system reboot described in this section.  If you change the node name after the subsystem has been correctly recognized by VMS, VMS will not recognize the new subsystem node name when you exit PARAMS. That is, if you execute the DCL command, SHOW CLUSTER, you will not see the subsystem's old or new node name in your table. If you try to use the subsystem, all applications will get errors indicating the subsystem is not present. To avoid problems, reboot VMS. Then, you can use the subsystem with its new node name. ------------------------------------------------------------ PARAMS Functions At the PARAMS> prompt, you can use the following commands: ------------------------------------------------------------ Use. . . To. . . ------------------------------------------------------------ HELP Display a list of available commands and usage format SHOW /ALL Display all subsystem parameters SHOW parameter Display a specific parameter SET parameter Set a parameter WRITE Save changes permanently in EEROM EXIT Exit from PARAMS ------------------------------------------------------------ ------------------------------------------------------------ Continued on next page 4-4 Using the TF85 PARAMS Program, Continued ------------------------------------------------------------ SHOW Command Use the SHOW command to display the settings of the subsystem parameters. The SHOW command has two formats: SHOW /ALL SHOW parameter To list all parameters, type: PARAMS> SHOW /ALL The list of parameters is long but includes five that you might want to change. In the following example, each row shows the parameter 's name, the parameter 's current value, the factory- set default value, the acceptable minimum and maximum values, and the format for representing the values: Parameter Current Default Minimum Maximum Radix UNITNUM 0 0 0 255 Decimal FORCEUNIT 1 1 0 1 Decimal NODENAME T8DBBB TF85 Ascii FORCENAME 0 0 0 1 Decimal SYSTEMID 420000F00002 Quad To display a specific parameter, type: PARAMS> SHOW systemid Parameter Current Default Minimum Maximum Radix SYSTEMID 420000F00002 Quad ------------------------------------------------------------ Continued on next page 4-5 Using the TF85 PARAMS Program, Continued ------------------------------------------------------------ SHOW Command (continued) The following table defines the five parameters: ------------------------------------------------------------ Parameter Definition ------------------------------------------------------------ UNITNUM TMSCP unit number. FORCEUNIT Determines whether the UNITNUM value or DSSI node ID is used to identify the TMSCP unit. If you set FORCEUNIT, then you should also assign UNITNUM to the desired value. UNITNUM means nothing when FORCEUNIT = 0. 1 -- Uses the DSSI node ID. 0 -- Uses the TMSCP unit number. NODENAME Node name for the TF85 subsystem. 1 Enter a 6-character name. (The factory setting is a unique string derived from the subsystem serial number.) FORCENAME 1 -- Uses a ``canned'' node name: TF85x, where x = A through H, depending on the DSSI node number value (0 through 7, respectively). 1 0 -- Uses the value set in NODENAME. SYSTEMID DSSI controller module's 48-bit (hex) system ID. It is recommended that you never change this value; it uniquely identifies your drive. ------------------------------------------------------------ 1 If you intend to change either NODENAME or FORCENAME, the system will not recognize the drive as available until you boot the VMS operation system. ------------------------------------------------------------ ------------------------------------------------------------ Continued on next page 4-6 Using the TF85 PARAMS Program, Continued ------------------------------------------------------------ SET Command Use the SET command to change parameters that you can list with the SHOW command. Syntax for the SET command is: SET parameter value In this example, parameter is the name of the parameter to be set and value is the value you want assigned to the parameter. CAUTION The controller module does range validation checking on each parameter. However, it is not guaranteed all combinations of settings will result in correct controller module operation. Parameters changed are not actually effective until you execute a WRITE command, described in the next section. If you forget to issue a WRITE command and try to EXIT, a warning message displays, telling you the parameter was modified but not written. NOTE If you request changing some parameters, the system will warn you that it must reset the controller to accept the changes. Details are in the EXIT Command section of this chapter. ------------------------------------------------------------ Continued on next page 4-7 Using the TF85 PARAMS Program, Continued ------------------------------------------------------------ WRITE Command Use the WRITE command to save, in nonvolatile memory, the changes you made using the SET command. The WRITE command is similar to the VMS SYSGEN WRITE command. The syntax is WRITE at the PARAMS> prompt. The program's response depends on which parameters you changed. If the change is allowed without resetting the controller, the response is merely the PARAMS> prompt. In the following example, the response requires user action: PARAMS> SET NODENAME TAPE1 PARAMS> SET UNITNUM 18 PARAMS> WRITE Changing NODENAME and UNITNUM each requires a reset (initialization) of the controller. PARAMS asks: Changes require controller initialization, ok? [Y/(N)] Y CAUTION Answering YES aborts the controller's current application, if any, and saves the parameters. Your changes take effect immediately and program control returns to the DCL command prompt. To avoid aborting the current application, answer NO. If you answer NO, all parameters changed using SET since the previous successfully completed WRITE command are ignored. You are returned to the PARAMS> prompt. See the next section, EXIT Command. The above example sets the TF85 subsystem's node name to TAPE1, and the TMSCP unit number to 18. Executing WRITE and answering YES to the controller initialization question saves the node name and unit number in EEROM and resets the controller. ------------------------------------------------------------ Continued on next page 4-8 Using the TF85 PARAMS Program, Continued ------------------------------------------------------------ EXIT Command Typing the EXIT command, at the PARAMS> prompt, ends the PARAMS program, and the word Completed appears on your screen. NOTE To exit from questions during the local program dialogue, type ------------------------------------------------------------ ------------------------------------------------------------ Ctrl/C ------------------------------------------------------------ ------------------------------------------------------------ , ------------------------------------------------------------ ------------------------------------------------------------ Ctrl/Z ------------------------------------------------------------ ------------------------------------------------------------ , or ------------------------------------------------------------ ------------------------------------------------------------ Ctrl/Y ------------------------------------------------------------ ------------------------------------------------------------ . In this case, your latest changes will be ignored. The following table describes what happens when you use the EXIT command: ------------------------------------------------------------ If you. . . Then the. . . ------------------------------------------------------------ Did not SET a parameter EXIT succeeds immediately. SET parameters and forgot to execute WRITE EXIT is ignored and you are advised: Parameter modified but not written. Still Exit? If you answer YES, the system EXITS and returns to the DCL prompt. Your modifications are not saved. If you answer NO, the system returns to the PARAMS> prompt. To save your modifications, enter WRITE at the prompt, and then EXIT. SET parameters and executed WRITE System EXITS and returns to the DCL prompt. ------------------------------------------------------------ ------------------------------------------------------------ 4-9 Using the TF85 DIRECT and HISTRY Utilities ------------------------------------------------------------ Starting DIRECT and HISTRY To start DIRECT or HISTRY, use the same procedure for starting PARAMS, but alter the value of /TASK in the SET HOST/DUP command: /TASK=DIRECT or /TASK=HISTRY The following example shows the SET HOST/DUP command with DIRECT or HISTRY as the task: $ SET HOST/DUP/SERVER=MSCP$DUP/TASK=DIRECT nodename $ SET HOST/DUP/SERVER=MSCP$DUP/TASK=HISTRY nodename Using DIRECT AND HISTRY requires no further user interaction. ------------------------------------------------------------ About DIRECT The DIRECT utility provides a directory of the diagnostic and utility programs resident in the TF85 subsystem. An example of a DIRECT display follows: DIRECT V1.0 D HISTRY V1.0 D PARAMS V1.0 D Completed ------------------------------------------------------------ Continued on next page 4-10 Using the TF85 DIRECT and HISTRY Utilities, Continued ------------------------------------------------------------ About HISTRY The HISTRY utility displays information about the history of the TF85 subsystem. An example of the HISTRY display follows: TF85 ! DSSI: T8MB3Q /3 (DIPs) Controller: " S#: EN03000170 HW: 000/PCB-rev:A000 Bt: 121/96626CC9 ( 8-APR-1991 21:10:48) # Cd: 001/0F1AA48E (22-MAR-1991 16:06:35) EE: 086.011 TD: 002 Drive: $ S#: EN04500464 HW: 000/A000 Cd: 033/E9DF EE: 020/6300 Loader (S/H/M): 000/000/000 Power on Hours: 1499 Power Cycles: 68 Completed Using the example above, the following list describes some of the information you see when you run HISTRY: ! Reflects your device's node name. The DSSI node name is encoded from the controller serial number. The /3 (DIPs) indicates that the DSSI node ID for this device is 3. " The serial number for the controller board. # The revision number of the controller software. $ The serial number for the tape drive. ------------------------------------------------------------ 4-11 Appendix A Tx85 Subsystem Specifications ------------------------------------------------------------ Mode of Operation The Tx85 subsytem operates in a streaming mode with a maximum transfer rate (at tape) of 800 kilobytes/s, formatted. ------------------------------------------------------------ Media The specified media for the TF85 subsystem is 12.77 mm (1/2 in) unformatted magnetic tape with the following characteristics:  Track density = 96 tracks/in (48 tracks)  Bit density = 42,500 bits/in  Number of tracks = 48  Tape speed = 100 in/s  Track format = Two-track parallel, serpentine recording  Cartridge capacity = Up to 2.6 gigabytes, formatted ------------------------------------------------------------ Power Consumption The TF85 subsystem consumes 56 W maximum. The TZ85 subsystem consumes 40 W maximum. ------------------------------------------------------------ Continued on next page A-1 Tx85 Subsystem Specifications Power Requirements The TF85 subsystem has the following power requirements:  12 V 5% @ 1.6 A (2.6 A surge), 75 mV ripple peak-to-peak  +5 V 5% @ 4.5 A, 75 mV ripple peak-to-peak The TZ85 subsystem has the following power requirements:  12 V 5% @ 1.2 A (1.5 A surge), 75 mV ripple peak-to-peak  +5 V 5% @ 3.5 A, 75 mV ripple peak-to-peak ------------------------------------------------------------ Continued on next page A-2 Appendix B Standard VMS Commands Using the Subsystem Efficiently ------------------------------------------------------------ Introduction This section identifies guidelines that you should follow to use the Tx85 subsystem effectively with your host application. To take best advantage of the subsystem's efficient processing abilities, you must use certain qualifiers with the MOUNT and BACKUP commands. This appendix describes those qualifiers and their appropriate values. ------------------------------------------------------------ Guidelines For efficient operation of the TF85 or the TZ85 subsystem:  Choose a large record size when mounting a tape. The maximum value, 65534, is recommended.  Do not use the COPY command to save more than 9,999 files onto the tape. The TF85 subsystem has an additional consideration for operating efficiency:  Be aware that the TF85 subsytem uses a default FORCECACHING parameter that enables the DSSI controller to cache write data to the drive. (See the discussion in TF85 FORCECACHING with the MOUNT Command.) ------------------------------------------------------------ B-1 Tape Commands ------------------------------------------------------------ Introduction The Tx85 cartridge tape subsystem uses most of the standard magnetic tape commands that can be invoked under VMS operating system, version 5.4 or later. This section discusses the following VMS commands used to operate the Tx85 subsystem: ------------------------------------------------------------ For this command. . . See page. . . ------------------------------------------------------------ ALLOCATE B-3 INITIALIZE B-3 MOUNT B-4 BACKUP B-5 COPY B-6 DISMOUNT B-6 DEALLOCATE B-6 ------------------------------------------------------------ ------------------------------------------------------------ For More Information This appendix is a reference only; it does not include all the details that may be involved in using VMS commands. For more information about VMS commands and command files, see the VAX/VMS Guide to Using Command Procedures (AA-H782B-TE), VAX/VMS Command Language User 's Guide (AA-DO23C-TE), or the VMS System Manager 's Guide. ------------------------------------------------------------ Continued on next page B-2 Tape Commands, Continued ------------------------------------------------------------ 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 Tx85 subsystem: $ ALLOCATE device_name: [logical name] For example, to allocate the Tx85 subsystem for your use and assign it to the logical name TAPE1, do the following: $ ALLOCATE MIA0: TAPE1 ------------------------------------------------------------ Using the INITIALIZE Command CAUTION Be sure to use a scratch tape before initializing; otherwise, any data 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 Tx85 tape drive. The tape must be write-enabled for the initializing operation. Use the following format: $ INITIALIZE device_name: [volume label] As an example, to initialize the device TAPE1 and assign the volume name GMB001, type the following: $ INITIALIZE MIA0: 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). ------------------------------------------------------------ Continued on next page B-3 Tape Commands, Continued ------------------------------------------------------------ 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. Use the following format to mount a tape with the Tx85 subsystem: $ MOUNT/FOREIGN/CACHE=TAPE_DATA device_name: [volume label] [logical name] As an example, to make TAPE1 available for processing, type the following: $ MOUNT/FOREIGN/CACHE=TAPE_DATA MIA0: GMB001 TAPE1 The screen displays a message: %MOUNT-I-MOUNTED, GMB001 mounted on MIA0: You must use the /FOREIGN qualifier when you are performing BACKUP commands. Do not use it when you are performing COPY commands. ------------------------------------------------------------ Continued on next page B-4 Tape Commands, Continued ------------------------------------------------------------ TF85 FORCECACHING with the MOUNT Command The TF85 DSSI controller has a parameter, accessible through the DUP PARAMS utility, that controls whether tape caching is done. This parameter is called FORCECACHING. Its default value is 1, which means that the controller always caches--even if you specify /NOCACHE with the MOUNT command, unless you also specify /READ_CHECK or /WRITE_CHECK. You can modify FORCECACHING to value 0, which allows the subsystem to honor the various means the application program has to specify that commands not be cached. CAUTION Setting FORCECACHING to 0 and specifying /NOCACHE with the MOUNT command can result in significant subsystem performance degredation. For more information, see the VAX/VMS Mount Utility Reference Manual (AA-Z424A-TE). ------------------------------------------------------------ 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: $ 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 VMS tape commands, see the VAX/VMS Backup Utility Reference Manual (AA-Z407B-TE). ------------------------------------------------------------ Continued on next page B-5 Tape Commands, Continued ------------------------------------------------------------ Using the COPY Command Use the COPY command, with the Tx85 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 MIA0 and assigns the logical name TAPE1. The COPY command uses the logical name TAPE1 for the input file specification. All files on MIA0 are copied to the current default disk and directory. The files keep their original file names and file types. $ MOUNT MIA0: GMB001 TAPE1: $ COPY TAPE1:*.* *.* NOTE Using the COPY command to move multiple files may not achieve optimum performance. Check with your system manager for more information. ------------------------------------------------------------ Using the DISMOUNT Command The DISMOUNT command cancels the previous MOUNT command, makes the unit unavailable for processing, and unloads the tape: $ DISMOUNT logical_name or device_name: ------------------------------------------------------------ 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 MIA0: or TAPE1 ------------------------------------------------------------ B-6 Appendix C Digital Services Service Plans ------------------------------------------------------------ Introduction Digital Equipment Corporation offers a range of flexible service plans. ------------------------------------------------------------ On-Site Service On-site service offers the convenience of service at your site and insurance against unplanned repair bills.
