a SBB tape drive SCSI ID is determined by the SBB physical slot.
8.2.2 Cabling the DS-TZ89N-VW Tape Drives
No special cabling is involved with the DS-TZ89N-VW as it is installed in
a BA356 StorageWorks enclosure. A DWZZB-VA installed in slot 0 of the
BA356 provides the connection to the shared SCSI bus.
You must remove the DWZZB-VW differential terminators. Ensure that
jumpers W1 and W2 are installed to enable the single-ended termination.
The BA356 jumper must be installed, and connector JB1 on the personality
module must be left open to provide termination at the other end of the
single-ended bus.
A trilink connector on the differential end of the DWZZB-VW allows
connection to the shared bus. If the BA356 containing the DS-TZ89N-VW is
on the end of the bus, install an H879-AA terminator on the trilink for that
BA356 to provide termination for the shared SCSI bus.
Figure 8–2 shows a TruCluster Server cluster with three shared SCSI buses.
One shared bus has a BA356 with a DS-TZ89N-VW at SCSI ID 2.
Table 8–2 shows the components used to create the cluster shown in
Figure 8–2.
