7.After the selection stops flashing and the control panel indicates that the change is not effective until a reboot, press the Enter button.
8.When the Special Configuration menu reappears, turn the power switch off and then on to cycle the power. The base module is now reconfigured as a slave to the TL890 expansion unit.
9.Repeat the steps for each TL891/TL892 base module present that is to be a slave to the TL890 expansion unit.
8.7.2.3Powering Up the DLT MiniLibrary
When turning on power to the DLT MiniLibrary, power must be applied to the TL890 expansion unit simultaneously or after power is applied to the the TL891/TL892 base modules. If the expansion unit is powered on first, its inventory of modules may be incorrect and the contents of some or all of the modules will be inacessible to the system and to the host.
When the expansion unit comes up, it will communicate with each base module through the expansion unit interface and inventory the number of base modules, tape drives, and cartridges present in each base module. After the MiniLibrary configuration has been determined, the expansion unit will communicate with each base module and indicate to the base module which cartridge group that base module contains. The cartridges slots are numbered by the expansion unit as follows:
•Expansion unit: 0 through 15
•Top TL891/TL892: 16 through 25
•Middle TL891/TL892: 26 through 35
•Bottom TL891/TL892: 36 through 45
When all initialization communication between the expansion module and each base module has completed, the base modules will display their cartridge numbers according to the remapped cartridge inventory.
For instance, the middle base module default screen would be displayed as follows:
DLT2 Idle
DLT3 Idle Loader Idle
26> _ _ _ _ _ _ _ _ _ _ <35
8.7.2.4 Setting the TL890/TL891/TL892 SCSI ID
After the base modules have been reconfigured as slaves, each base module control panel still provides tape drive status and error information, but all
