Management Module Service Processor Problems; Memory Problems - IBM power PS700 Problem Determination And Service Manual

Management module service processor problems

Determine if a problem is a management module service processor problem and, if so, the corrective
action to take.
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 8406," on page 229 to determine which components are CRUs and which
components are 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
Service processor in the
management module reports a
general monitor failure.

Memory problems

Identify memory problem symptoms and what corrective actions to take.
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 8406," on page 229 to determine which components are CRUs and which
components are 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
The amount of system memory
displayed is less than the
amount of physical memory
installed.
Action
Disconnect the BladeCenter unit from all electrical sources, wait for 30 seconds,
reconnect the BladeCenter unit to the electrical sources, and restart the blade
server.
If the problem remains, see "Solving undetermined problems" on page 227, or the
Advanced Management Module Guide
Action
1. Make sure that:
v All installed memory is listed in the output of the lscfg -vp command.
v The memory modules are seated properly.
v You have installed the correct type of memory.
v All banks of memory on the DIMMs are enabled. The blade server might
have automatically disabled a DIMM bank when it detected a problem or a
DIMM bank could have been manually disabled.
2. Check the Advanced Management Module event log for an error message.
v If the DIMM was disabled by a system-management interrupt (SMI), replace
the DIMM.
v If the DIMM was disabled by the POST, obtain the eight-digit error code
and location code and replace the failing DIMM.
3. Reseat the DIMM.
4. Replace the DIMM.
5. Replace the system-board.
