Error logs
The system event/error log includes error codes and messages that were generated
during POST. The BMC (baseboard management controller) system event log
contains both event messages and error codes that were generated by the BMC
(see “BMC system-event log messages” on page 109).
The BMC system event log is limited in size. When the log is full, new entries will
not overwrite existing entries; therefore, you must periodically clear the log through
the Configuration/Setup Utility program (see “Clearing the error logs”). When you
are troubleshooting an error, be sure to clear the error logs so that you can find
current errors more easily.
Important: After you complete a repair or correct an error, clear the BMC system
event log (see “Clearing the error logs”) to turn off the system-error LED on the
front of the server.
You can view the contents of both the system event/error log and the BMC
system-event log from the Configuration/Setup Utility program.
When you are troubleshooting PCI Express slots, note that the error logs report the
PCI Express busses numerically. The numerical assignments vary depending on the
configuration. You can check the assignments by running the Configuration/Setup
Utility program (see the
User’s Guide on the IBM System x Documentation CD for
more information).
Viewing error logs from the Configuration/Setup Utility program
For complete information about using the Configuration/Setup Utility program, see
the
User’s Guide on the IBM System x Documentation CD. For a list of system
event codes and error codes, see “BMC system-event log messages” on page 109.
