SCSI Termination,
Continued
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.
