Hard Disk Drive Problems; Intermittent Problems - IBM x iDataPlex dx340 Series Problem Determination And Service Manual

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 Chapter 3, "Parts listing," on page 59 to determine which components are customer replaceable units
(CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.
Symptom
Not all drives are recognized by
the hard disk drive diagnostic
test.
The system-board tray stops
responding during the hard disk
drive diagnostic test.
A hard disk drive was not
detected while the operating
system was being started.
A hard disk drive passes the
hard disk drive diagnostic test,
but the problem remains.
A hard disk drive was not
detected by the controller.

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," on page 59 to determine which components are customer replaceable units
(CRU) and which components are field replaceable units (FRU).
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
Remove the drive that is indicated by 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.
Remove the hard disk drive that was being tested when the system-board tray
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.
Reseat all hard disk drives and cables; then, run the hard disk drive diagnostic
tests again.
Run the hard disk drive diagnostic test again. If the drive continues to pass the test
but continues to have a problem, replace the drive with a new one.
Reseat all hard disk drives and cables; then, run the hard disk drive diagnostic
tests again.
Action
1. Make sure that:
v All cables are connected securely to the front of the system-board tray and
the power cord is connected securely to the rear of the chassis.
v When the system-board tray is turned on, air is flowing from the rear of the
chassis. If there is no airflow, the fan assembly is not working. This causes
the system-board tray to overheat and shut down.
2. Check the BMC system event log (see "Error logs" on page 18).
3. See "Solving undetermined problems" on page 57.
