Service processor (BMC) error codes

The baseboard management controller (BMC) log contains up to 512 of the most
recent service processor errors in IPMI format. These messages are a combination
of plain text and error code numbers. You can view the BMC log from the
Configuration/Setup Utility menu by selecting Advanced Setup > Baseboard
Management Controller (BMC) Settings > BMC System Event Log.
You can view additional information and error codes in plain text by viewing the
management-module event log in your BladeCenter unit.

Solving SAS hard disk drive problems

For any SAS error message, one or more of the following devices might be causing
the problem:
v A failing SAS device (adapter, drive, or controller)
v An improper SAS configuration
For any SAS error message, make sure that the SAS devices are configured
correctly.

Solving undetermined problems

Note: When you are diagnosing a problem in the blade server, you must determine
whether the problem is in the blade server or in the BladeCenter unit.
v If all of the blade servers have the same symptom, it is probably a BladeCenter
v If the BladeCenter unit contains more than one blade server and only one of the
If the diagnostic tests did not diagnose the failure or if the blade server is
inoperative, use the information in this section.
If you suspect that a software problem is causing failures (continuous or
intermittent), see "Software problems" on page 37.
Damaged data in CMOS memory or damaged BIOS code can cause undetermined
problems. To reset the CMOS data, remove and replace the battery to override the
power-on password and clear the CMOS memory; see "Removing the battery" on
page 70. If you suspect that the BIOS code is damaged, see "Recovering from a
BIOS update failure" on page 48.
