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.
Warning
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.
