Event logs
Error codes and messages are displayed in POST event log, system-event log, integrated management
module (IMM2) event log, and DSA event log.
•
POST event log:
This log contains the three most recent error codes and messages that were generated
during POST. You can view the contents of the POST event log from the Setup utility (see “Starting the
Setup utility” on page 93). For more information about POST error codes, see Appendix B “UEFI/POST
diagnostic codes” on page 691.
•
System-event log:
This log contains POST and system management interrupt (SMI) events and all
events that are generated by the baseboard management controller that is embedded in the integrated
management module (IMM). You can view the contents of the system-event log through the Setup
utility and through the Dynamic System Analysis (DSA) program (as IPMI event log). The system-event
log is limited in size. When it is full, new entries will not overwrite existing entries; therefore, you must
periodically clear the system-event log through the Setup utility. When you are troubleshooting an error,
