Drives are missing
from the show
config display.
Drives have
duplicate SCSI IDs.
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.
SCSI bus not
properly
terminated.
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.
