drive diagnostic tests 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 Fixed Disk Test (see “Running DSA Preboot diagnostic
programs” on page 57).
Note: This test is not available on servers that have RAID arrays or servers that have
SATA hard disk drives.
