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.
Refer to “SCSI Hard-Disk Drive Indicator Codes” in Chapter 3 for descriptions of the
other drive indicator patterns.
Use the following procedure to troubleshoot a hard-disk drive problem.
