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.
8.7.2.3 Powering 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
