4.3.1 Setting the Internal Drive SCSI ID
Each device on the SCSI bus must have a unique SCSI ID address assigned to it.
For specific recommendations for assigning SCSI IDs, refer to your system or
SCSI controller documentation.
The SCSI ID is set using jumpers on a set of pins at the rear of the drive. This
section discusses setting the SCSI ID on the internal drive via the jumper block.
Table 4-1 and Table 4-2 show the SCSI ID address and jumper settings.
Figure 4-1 shows the empty jumper block that you use to set the SCSI ID. If you
decide it is necessary to change the tape drive’s SCSI ID, use your fingers to move
the jumpers to the pattern corresponding to the ID you want (see
Figure 4-1 and
the related table of SCSI jumper settings in Table 4-1 on page 4-8 and Table 4-2 on
page 4-10 ).
Figure 4-1. Detail of the Empty SCSI ID Jumper Block
Internal drives can be configured for SCSI ID addresses that range from 0 to 15 in
one of two ways:
•
Jumper the 10-pin SCSI ID block located on the back of the drive ( Figure 4-2
on page 4-9 ), OR
•
In a library setting, you can set the IDs through firmware. (The firmware
default = SCSI ID 5 and assumes no jumpers are installed on the jumper
block.)
The default setting for the tape drive is 5; the host adapter setting is typically SCSI
ID 7. If you choose to omit all jumpers from the SCSI ID block, the tape drive will
use the default setting of 5.
