Error logs
The BMC log contains all system status messages from the blade server service
processor. The management-module event log in your BladeCenter unit contains
messages that were generated on each blade server during POST and status
messages from the BladeCenter service processor. (See the documentation for the
management module in your BladeCenter unit type.)
The following illustration shows an example of a BMC log entry.

Important:
v
A single problem might cause several error messages. When this occurs, work to
correct the cause of the first error message. After you correct the cause of the
first error message, the other error messages usually will not occur the next time
you run the test.
v
The management-module event log in your BladeCenter unit lists messages
according to the position of the blade server in the blade bays. If a blade server
is moved from one bay to another, the management-module event log will report
messages for that blade server using the new bay number; messages for that
blade server that were generated prior to the move will still be listed using the
previous bay number.
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
Installation and 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 .
