Viewing the system event log
The system event log (SEL) contains information about all the POST and system management interrupt (SMI)
events. You can view the SEL to diagnose system problems.
The TSM implements the SEL as specified in the IPMI 2.0 specification. The SEL is accessible regardless of
the system power state through the TSM in-band and out-of-band interfaces.
For more information about viewing the SEL, refer to the ThinkServer System Manager User Guide, which is
available for download at http://www.lenovo.com/UserManuals.
