Hard disk drive problems
Symptom FRU/action
Not all drives are recognized by
the hard disk drive diagnostic
test (the Fixed Disk test).
1. Remove the first drive not recognized and try the hard disk drive
diagnostic test again.
2. If the remaining drives are recognized, replace the drive that you removed with
a new one.
The computer stops responding
during hard disk drive diagnostic
test.
1. Remove the hard disk drive being tested when the computer stopped
responding and try the diagnostic test again.
2. If the hard disk drive diagnostic test runs successfully, replace the drive you
removed with a new one.
A hard disk drive passes the
diagnostic Fixed Disk Test but
the problem remains.
Run the diagnostic SCSI Fixed Disk Test (see “Starting the diagnostic programs
and viewing the test log” on page 13.
Note: This test is not available on servers that have RAID arrays or servers that
have IDE or SATA hard disk drives.
IEEE 1394 (firewire) port problems
Symptom FRU/action
An IEEE 1394 device does not
work.
Make sure that:
v
The correct IEEE 1394 device driver is installed.
v The operating system supports IEEE 1394 devices.
Intermittent problems
Symptom FRU/action
A problem occurs only

v All cables and cords are connected securely to the rear of the computer and
attached options.
v When the computer is turned on, air is flowing from the rear of the computer
at the fan grille. If there is no airflow, the fan is not working. This causes the

device in each SCSI chain is terminated correctly.
2. Check the system-error log.
