6.2.4.6 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
Caution:
Since all non-disk SCSI devices are single ended, it is not
advisable to attach a non-disk device to a MegaRAID SCSI
320-1 RAID controller if LVD disk drives are also attached.
This is because the SCSI bus will then operate in single-
ended mode.
