1 TL891 and TL892 DLT MiniLibraries This technical update to the TruCluster Software Products Hardware Configuration manual provides important information about support for the TL891 and TL892 Digital Linear Tape (DLT) MiniLibraries with the TruCluster Production Server Software Version 1.5 and TruCluster Available Server Software Version 1.5 products.
1.1 General Overview The TL891 and TL892 DLT MiniLibraries were recently qualified for use with the TruCluster Production Server Software Version 1.5 and TruCluster Available Server Software Version 1.5 products. There is no TruCluster Software Products software release that coincides with the availability of support for the TL891 and TL892, so this technical update provides the TL891/TL892 configuration information that would be in Chapter 4 of the TruCluster Software Products Hardware Configuration manual.
1.2 TL891 and TL892 DLT MiniLibraries Overview The TZ89 DLT MiniLibrary family includes the following hardware: •
DS-TL891-NE/NG: A rack mount MiniLibrary with bar code reader, robotic controller, one TZ89N-AV tape drive, and a 10-cartridge removable magazine.
•
DS-TL891-NT: A tabletop MiniLibrary with bar code reader, robotic controller, one TZ89N-AV tape drive, and a 10-cartridge removable magazine.
•
DS-TL892-UA: An upgrade kit that includes one TZ89N-AV tape drive to upgrade either TL891 model to a TL892 model.
The TL891 and TL892 MiniLibraries use a 10-cartridge magazine with a random-access loader mechanism. The magazine holds either CompacTape III, CompacTape IIIXT, or CompacTape IV cartridges. In the TL892 two-drive model, the library robotics can load any of the cartridges in the system into either of the TZ89 tape drives.
TL891 and TL892 DLT MiniLibraries 1–1
The total capacity of one base module using CompacTape IV media is 350 GB uncompressed (10 cartridges, 35 GB per cartridge). The SCSI bus connectors are HD 68-pin, and the SCSI transfer is high-speed differential. Tape devices are supported only on those shared SCSI buses that use KZPSA PCI SCSI adapters.

2 Preparing the TL891 and TL892 DLT MiniLibraries The topics in this chapter provide information on preparing the TL891 and TL892 DLT MiniLibraries for use on a shared SCSI bus with the TruCluster Production Server Software Version 1.5 and TruCluster Available Server Software Version 1.5 products. _______________________
Note
_______________________
To achieve system performance capabilities, DIGITAL recommends placing no more than two TZ89 drives on a SCSI bus, and also recommends that no shared storage be placed on the same SCSI bus with a tape library.
2.1 Preparing the TL891 or TL892 DLT MiniLibrary for Shared SCSI Usage The TL891 and TL892 MiniLibraries use one (TL891) or two (TL892) TZ89N-AV differential tape drives and a robotics controller, which access cartridges in a 10-cartridge magazine. Each tape drive present, and the robotics controller, have individual SCSI IDs. There are six 68-pin, high-density SCSI connectors located on the back of the MiniLibrary; two SCSI connectors for each drive and two for the robotics controller. The TL891 uses a 0.3-meter SCSI bus jumper cable (part of the TL891 package) to place the robotics controller and tape drive on the same SCSI bus. When upgrading to the TL892, you can place the second drive on the same SCSI bus (another 0.3-meter SCSI bus jumper cable is supplied with the DS-TL892-UA upgrade kit) or place it on its own SCSI bus. The following sections describe how to prepare the TL891 and TL892 in more detail.

2.1.1 Setting the TL891 or TL892 SCSI ID The control panel on the front of the TL891 and TL892 MiniLibraries is used to display power-on self-test (POST) status, display messages, and to set up MiniLibrary functions. When power is first applied to a MiniLibrary, a series of POST diagnostics are performed. During POST execution, the MiniLibrary model number, current date and time, firmware revision, and the status of each test is displayed on the control panel. After the POST diagnostics have completed, the default screen is shown: DLT0 Idle DLT1 Idle Loader Idle 0> _ _ _ _ _ _ _ _ _ _ <9
The first and second lines of the default screen show the status of the two (if present) drives. The third line shows the status of the library robotics, and the fourth line is a map of the magazine, with the numbers from 0 to 9 representing the cartridge slots. Rectangles present on this line indicate cartridges present in the corresponding slot of the magazine. For example, this fourth line (0> X X _ _ _ _ _ _ _ _ <9, where the X’s represent rectangles) indicates that cartridges are installed in slots 0 and 1. _______________________
Note
_______________________
There are no switches for setting a mechanical SCSI ID for the tape drives. The SCSI IDs default to five. The MiniLibrary sets the electronic SCSI ID very quickly, before any device can probe the MiniLibrary, so the lack of a mechanical SCSI ID does not cause any problems on the SCSI bus.
To set the SCSI ID, follow these steps: 1.
From the Default Screen, press the Enter button to enter the Menu Mode, displaying the Main Menu. _____________________
Note
_____________________
When you enter the Menu Mode, the Ready light goes out, an indication that the module is off line, and all medium changer commands from the host return a SCSI "not ready"

status until you exit the Menu Mode and the Ready light comes on once again.
2.
Depress the down arrow button until the Configure Menu item is selected, then press the Enter button to display the Configure submenu. _____________________
Note
_____________________
The control panel up and down arrows have an auto-repeat feature. When you press either button for more than one-half second, the control panel behaves as if you were pressing the button about four times per second. The effect stops when you release the button.
3.
Press the down arrow button until the Set SCSI item is selected and press the Enter button.
4.
Select the tape drive (DLT0 Bus ID: or DLT1 Bus ID:) or library robotics (LIB Bus ID:) for which you wish to change the SCSI bus ID. The default SCSI IDs are as follows: •
Lib Bus ID: 0
•
DLT0 Bus ID: 4
•
DLT1 Bus ID: 5
Use the up or down arrow button to select the item for which you need to change the SCSI ID. Press the Enter button. 5.
Use the up or down arrow button to scroll through the possible SCSI ID settings. Press the Enter button when the desired SCSI ID is displayed.
6.
Repeat steps 4 and 5 to set other SCSI bus IDs as necessary.
7.
Press the Escape button repeatedly until the default menu is displayed.
2.1.2 Cabling the TL891 or TL892 MiniLibraries There are six 68-pin, high-density SCSI connectors on the back of the TL891. The two leftmost connectors are for the library robotics controller. The middle two are for tape drive one. The two on the right are for tape drive two (if the TL892 upgrade has been installed).

Note
_______________________
The tape drive SCSI connectors are labeled DLT1 (tape drive 1) and DLT2 (tape drive 2). The control panel designation for the drives is DLT0 (tape drive 1) and DLT1 (tape drive 2).
The default for the DLT MiniLibrary TL891 is to place the robotics controller and tape drive 1 on the same SCSI bus. A 0.3-meter SCSI jumper cable is provided with the unit. Plug this cable into the second connector (from the left) and the third connector. If the MiniLibrary has been upgraded to two drives, place the second drive on the same SCSI bus with another 0.3-meter SCSI bus jumper cable, or place it on its own SCSI bus. _______________________
Note
_______________________
To achieve system performance cababilities, DIGITAL recommends placing no more than two TZ89 tape drives on a SCSI bus. The internal cabling of the TL891 and TL892 is too long to allow external termination with a trilink/H879-AA combination. Therefore, the TL891 or TL892 must be the last device on the shared SCSI bus. They may not be removed from the shared SCSI bus without stopping all ASE services that generate activity on the bus. For this reason, DIGITAL recommends that tape devices be placed on separate shared SCSI buses, and that there be no storage devices on the SCSI bus.
The cabling depends on whether or not there are one or two drives, and for the two-drive configuration, if each drive is on a separate SCSI bus. _______________________
Note
_______________________
It is assumed that the library robotics is on the same SCSI bus as tape drive 1.
To connect the library robotics and one drive to a single shared SCSI bus, follow these steps: 1.
Connect a BN21K or BN21L between the last trilink connector on the bus to the leftmost connector (as viewed from the rear) of the TL891.

2.
Install a 0.3-meter SCSI bus jumper between the rightmost robotics connector (second connector from the left) and the left DLT1 connector (the third connector from the left).
3.
Install an H879-AA terminator on the right DLT1 connector (the fourth connector from the left).
To connect the drive robotics and two drives to a single shared SCSI bus, follow these steps: 1.
Connect a BN21K or BN21L between the last trilink connector on the bus to the leftmost connector (as viewed from the rear) of the TL892.
2.
Install a 0.3-meter SCSI bus jumper between the rightmost robotics connector (the second connector from the left) and the left DLT1 connector (the third connector from the left).
3.
Install a 0.3-meter SCSI bus jumper between the rightmost DLT1 connector (the fourth connector from the left) and the left DLT2 connector (the fifth connector from the left).
4.
Install an H879-AA terminator on the right DLT2 connector (the rightmost connector).
To connect the drive robotics and one drive to one shared SCSI bus and the second drive to a second shared SCSI bus, follow these steps: 1.
Connect a BN21K or BN21L between the last trilink connector on one shared SCSI bus to the leftmost connector (as viewed from the rear) of the TL892.
2.
Connect a BN21K or BN21L between the last trilink connector on the second shared SCSI bus to the left DLT2 connector (the fifth connector from the left).
3.
Install a 0.3-meter SCSI bus jumper between the rightmost robotics connector (the second connector from the left) and the left DLT1 connector (the third connector from the left).
4.
Install an H879-AA terminator on the right DLT1 connector (the fourth connector from the left) and install another H879-AA terminator on the right DLT2 connector (the rightmost connector).
