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 4, "Parts listing, System x3200 M3 Types 7327 and 7328," on page 133 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
Reseat all hard disk drives and cables; then, run the hard disk drive diagnostic
tests again.
Run the diagnostic SCSI Attached Disk Test (see "Running the diagnostic
programs" on page 74).
Note: This test is supported on server models with RAID arrays that use the
ServeRAID-BR10il v2, ServeRAID-MR10i, or ServeRAID-MR10is controllers or
servers with SATA hard disk drives that use the onboard SATA/SAS controller to
create RAID arrays. Use the Fixed Disk Test for SATA hard disk drives or servers
that have RAID arrays.
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 IMM system event log (see "Event logs" on page
24).
