8.9.3 TL894 Tape Library Internal Cabling
The default internal cabling configuration for the TL894 tape library has the
robotics controller and top drive (drive 0) on SCSI bus port 1. Drive 1 is on
SCSI bus port 2, drive 2 is on SCSI port 3, and drive 3 is on SCSI bus port 4.
A terminator (part number 0415619) is connected to each of the drives to
provide termination at that end of the SCSI bus.
This configuration, called the four-bus configuration, is shown in
Figure 8–12. In this configuration, each of the tape drives, except SCSI bus
drive 0 and the robotics controller, requires a SCSI address on a separate
SCSI bus. The robotics controller and drive 0 use two SCSI IDs on their
SCSI bus.
