Table 2-3 Mass Storage Problems

Symptom
Drives are missing
from the show
config display.
Problem
Drives have
duplicate SCSI IDs.
SCSI bus not
properly
terminated.
Power-Up Diagnostics and Display
Corrective Action
Correct SCSI IDs.
Note: Internal hard disk drives are
automatically assigned SCSI IDs 0, 1,
2, and 3 (from left to right for
pedestal systems; and bottom to top
for rackmount systems). The onboard
controller is assigned SCSI ID 7, and
the CD-ROM, SCSI ID 4.
Check the following jumpers and
terminator to ensure that proper
termination is provided for all
internal SCSI devices.
The SCSI terminator jumper (J51) on
the system motherboard should be set
to "on." Refer to Appendix A.
The J5 jumper on the hard disk drive
backplane should be set as shown in
Appendix A.
The cable terminator at the end of the
SCSI removable media cable should
be properly seated.
For controllers other than the onboard
controller, the pk*0_soft_term
environment variable is used to
enable/disable SCSI terminators.
Refer to Table 6-1.
