Possible Failing FRU
Do the following:
1. Go to the processor
configuration/deconfiguration menu, which is
under the system information menu in the
service processor menus.
Look at the status of the processors. If any
of the processors have a status of
"manually deconfigured," reconfigure the
processor(s) and boot the system to the
SMS menus. Power down the system; look
again at the status of the processors.
If all of the processors are still configured in
the processor configuration/deconfiguration
menu, the problem has been resolved.
If any of the processors have a status of
"deconfigured by the system," either before
or after the boot to the SMS menus, replace
the processor MCM (on which the
deconfigured processor resides) specified
by the location code.
