Symptom Action
A hard disk drive passes the
diagnostic Fixed Disk Test but
the problem remains.
Run the diagnostic SCSI Attached Disk Test (see “Running the diagnostic
programs” on page 94).
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.
Intermittent problems
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See Chapter 3, “Parts listing, Type 4364, 4365, or 4366 server,” on page 15 to determine which

Symptom Action
A problem occurs only
occasionally and is difficult to
diagnose.
1. Make sure that:
v All cables and cords are connected securely to the rear of the server and
attached devices.
v When the server is turned on, air is flowing from the fan grille. If there is no
airflow, the fan is not working. This can cause the server to overheat and
shut down.
2. Check the system-error logs (see “Error logs” on page 70).
3. See Solving undetermined problems.
