6.2.5.5 Connecting Non-Disk SCSI Devices
SCSI tape drives and SCSI CD-ROM drives must each have a unique
SCSI ID regardless of the SCSI channel they are attached to. The
general rule for Unix systems is:
•
Tape drive set to SCSI ID 2
•
CD-ROM drive set to SCSI ID 5
Make sure that no hard drives are attached to the same SCSI Channel
as the non-disk SCSI devices. Drive performance will be significantly
degraded if SCSI hard disk drives are attached to this channel.
