Event logs
Error codes and messages 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 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 34). For more information about POST error codes, see Appendix B “UEFI/POST
diagnostic codes” on page 693.
• 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,
you might have to save and then clear the system-event log to make the most recent events available for
analysis. For more information about the system-event log, see Appendix A “Integrated Management
Module 2.1 (IMM2.1) error messages” on page 199.
Messages are listed on the left side of the screen, and details about the selected message are displayed
on the right side of the screen. To move from one entry to the next, use the Up Arrow () and Down Arrow ()
keys.
Some IMM sensors cause assertion events to be logged when their setpoints are reached. When a
setpoint condition no longer exists, a corresponding deassertion event is logged. However, not all events
are assertion-type events.
• Integrated management module II (IMM2) event log: This log contains a filtered subset of all IMM,
POST, and system management interrupt (SMI) events. You can view the IMM event log through the IMM
web interface. For more information, see “Logging on to the web interface” on page 43. You can also view
the IMM event log through the Dynamic System Analysis (DSA) program (as the ASM event log). For more
information about IMM error messages, see Appendix A “Integrated Management Module 2.1 (IMM2.1)
error messages” on page 199.
• DSA event log: This log is generated by the Dynamic System Analysis (DSA) program, and it is a
chronologically ordered merge of the system-event log (as the IPMI event log), the IMM chassis-event log
(as the ASM event log), and the operating-system event logs. You can view the DSA event log through the
DSA program (see “Viewing event logs without restarting the server” on page 62). For more information
about DSA and DSA messages, see “Lenovo Dynamic System Analysis” on page 64 and Appendix C
“DSA diagnostic test results” on page 715.
Viewing event logs through the Setup utility
Use this information to view the event logs through the Setup utility.
To view the POST event log or system-event log, complete the following steps:
Step 1. Turn on the server.
Step 2. When the prompt <F1> Setup is displayed, press
F1
. If you have set both a power-on password
and an administrator password, you must type the administrator password to view the event logs.
Step 3. Select System Event Log and use one of the following procedures:
• To view the POST event log, select POST Event Viewer .
• To view the system-event log, select System Event Log .
