System event log
The system event log contains messages of three types:
Information
Information messages do not require action; they record significant
system-level events, such as when the server is started.
Warning
Warning messages do not require immediate action; they indicate possible
problems, such as when the recommended maximum ambient temperature
is exceeded.
Error Error messages might require action; they indicate system errors, such as
when a fan is not detected.
Each message contains date and time information, and it indicates the source of
the message (POST or the IMM2).
Integrated management module II (IMM2) error messages
The following table describes the IMM2 error messages and suggested actions to
correct the detected problems.
For more information about IMM2, see the Integrated Management Module II User's
Guide at http://www-947.ibm.com/support/entry/portal/docdisplay?brand=5000008
&lndocid=MIGR-5086346.
Note: Deassertive events not listed in this table are informational only.
Table 6. IMM2 error messages
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v If an action step is preceded by “(Trained technician only),” that step must be performed only by a trained
technician.
