The BMC log is limited in size. When the log is full, new entries will not overwrite
existing entries; therefore, you must periodically clear the BMC log through the
Configuration/Setup Utility program (the menu choices are described in the User's
Guide). When you are troubleshooting an error, be sure to clear the BMC log so
that you can find current errors more easily.
Entries that are written to the BMC log during the early phase of POST show an
incorrect date and time as the default time stamp; however, the date and time are
corrected as POST continues.
Each BMC log entry appears on its own page. To display all the data for an entry,
use the Up Arrow (↑) and Down Arrow (↓) keys or the Page Up and Page Down
keys. To move from one entry to the next, select Get Next Entry or Get Previous
Entry.
The log indicates an assertion event when an event has occurred. It indicates a
deassertion event when the event is no longer occurring.
Some of the error codes and messages in the BMC log are abbreviated.
If you view the BMC log through the Web interface of the optional Remote
Supervisor Adapter II SlimLine, the messages can be translated.
You can view the contents of the POST error log, the BMC log, and the
system-error log from the Configuration/Setup Utility program. You can view the
contents of the BMC log also from the diagnostic programs.
When you are troubleshooting PCI-X slots, note that the error logs report the PCI-X
buses 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 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.
To view the error logs, complete the following steps:
1. Turn on the server.
2. When the prompt Press F1 for Configuration/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 error logs.
Note: If you forgot the power-on password or administrator password, you can
change the position of the jumper on pin 2 (boot block/clear CMOS) of SW4 to
the On position to bypass the password check. This enables you to reset the
passwords.
3. Use one of the following procedures:
v To view the POST error log, select Error Logs, and then select POST Error
Log.
v To view the BMC log, select Advanced Settings, select Baseboard
Management Controller (BMC) settings, and then select BMC System
Event Log.
v To view the system-error log (available only if an optional Remote Supervisor
Adapter II SlimLine is installed), select Event/Error Logs, and then select
System Event/Error Log.
