Hard-disk drive problems can be caused by a number of conditions, including prob-
lems with the drive itself, the SCSI backplane board, or a cable connected to the SCSI
backplane board.
The SCSI backplane board monitors the SCSI hard-disk drives connected to the back-
plane board. In the event of a drive failure, systems using the optional Dell PowerEdge
Expandable RAID Controller host adapter card will issue the following signals using
the drive indicator lights adjacent to each SCSI hard-disk drive:
If a drive shows signs of imminent failure, the drive online indicator stays on and
the drive failure indicator blinks on briefly each second.
If a drive has failed, the drive online indicator turns off and the drive failure indica-
tor blinks off briefly each second.
Other drive indicator patterns are listed in Table 3-4.
Use the following procedure to troubleshoot a hard-disk drive problem.
1. If the onboard SCSI host adapter is being used to control the SCSI backplane
board, reboot the system and press <F2> to enter the System Setup program.
