8.7 Preparing the TL890 DLT MiniLibrary Expansion Unit

The topics in this section provide information on preparing the TL890 DLT

MiniLibrary expansion unit with theTL891 and TL892 DLT MiniLibraries

for use on a shared SCSI bus.

______________________ Note _______________________

Toachieve system performance capabilities, we recommend

placing no more than two TZ89 drives on a SCSI bus, and also

recommend that no shared storage be placed on the same SCSI

bus with a tape library.
