This produces a list similar to:
sd0 at esp0: target 0 lun 0 sd6 at esp0: target 6 lun 0
This indicates that SCSI IDs 0 and 6 are used for existing devices. SCSI ID
7 is generally used for the adapter itself. In this situation, you would use a
SCSI ID from 1 to 5 for the new tape drive.
Note Use the switch settings shown in
