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, Type 8863," on page 105 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 Fixed Disk test).
The server stops responding
during the hard disk drive
diagnostic test.
A hard disk drive was not
detected while the operating
system was being started.
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 8863," on page 105 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
A problem occurs only
occasionally and is difficult to
diagnose.
Action
If the part is a CRU, replace it. If the part is a FRU, the part must be replaced by a
trained service technician.
Action
Remove the drive indicated on 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 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.
Reseat all hard disk drives and cables; then, run the hard disk drive diagnostic
tests again.
Action
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 log or BMC log (see "Error logs" on page 18).
