Hard disk drive 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 the parts listing in the Hardware Maintenance Manual to determine which components are customer

replaceable units (CRUs) and which components are field replaceable units (FRUs).

v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a

trained service technician.

Symptom Action

Not all drives are recognized by

the hard disk drive diagnostic

tests.

Remove the drive that is indicated by the diagnostic tests; then, run the hard disk

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 the diagnostic programs”

on page 174).

Note: This test is not available on servers that have RAID arrays or servers that

have SATA hard disk drives.

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 the parts listing in the Hardware Maintenance Manual to determine which components are customer

replaceable units (CRUs) and which components are field replaceable units (FRUs).

v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a

trained service technician.

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-event log or IMM log (see “Event logs” on page 140).

3. See “Solving undetermined problems” on page 140.
