Connecting Non-Disk SCSI Devices SCSI Tape drives, scanners, CD-ROM drives, and other non-disk

drive devices 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 disk 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.

Since all non-disk SCSI devices are single ended, it is not

advisable to attach a non-disk device to a MegaRAID Express

500 RAID controller if LVD disk drives are also attached because

the SCSI bus will then operate in single ended mode.
