Symptom Action
Not all drives are recognized by
the hard disk drive diagnostic
test (the Fixed Disk test).
Remove the drive indicated on the diagnostic tests; then, run the hard disk drive
diagnostic test again. If the remaining drives are recognized, replace the drive that
you removed with a new one.
The server stops responding
during the hard disk drive
diagnostic test.
Remove the hard disk drive that was being tested when the server stopped
responding, and run the diagnostic test again. If the hard disk drive diagnostic test
runs successfully, replace the drive that you removed with a new one.

A hard disk drive was not

detected while the operating
system was being started.
Reseat all hard disk drives and cables; then, run the hard disk drive diagnostic
tests again.

A hard disk drive passes the

diagnostic Fixed Disk Test but
the problem remains.
Run the diagnostic SCSI Attached Disk Test.

Note: Use the SCSI Attached Disk test for drives that are part of RAID arrays. Use

the Fixed Disk Test for SATA drives that are not part of RAID arrays.
