Error logs
The power-on self-test (POST), the hypervisor, and the service processor write errors to the BladeCenter
management module event log.
Select the Monitors → Event Log option in the management module Web interface to view entries that are
currently stored in the management-module event log. This log includes entries for events that are
detected by the blade servers. The log displays the most recent entries first.
The following table shows the syntax of a nine-word B700xxxx SRC as it might be displayed in the event
log of the management module.
The first word of the SRC in this example is the message identifier, B7001111. This example numbers each
word after the first word to show relative word positions. The seventh word is the direct select address,
which is 77777777 in the example.

Depending on your operating system and the utilities you have installed, error messages might also be
stored in an operating system log. See the documentation that comes with the operating system for more
information.
See the online information or the BladeCenter Management Module User's Guide for more information about
the event log.
Checkout procedure
The checkout procedure is the sequence of tasks that you should follow to diagnose a problem in the
blade server.
About the checkout procedure
Review this information before performing the checkout procedure.
v Read the Safety topic and the "Installation guidelines" on page 229.
v The firmware diagnostic program provides the primary methods of testing the major components of
the blade server. If you are not sure whether a problem is caused by the hardware or by the software,
you can use the firmware diagnostic program to confirm that the hardware is working correctly. The
firmware diagnostic program runs automatically when the blade server is turned on.
v A single problem might cause more than one error message. When this happens, correct the cause of
the first error message. The other error messages usually will not occur the next time you run the
diagnostic programs.
Exception: If there are multiple error codes or light path diagnostic LEDs that indicate a
microprocessor error, the error might be in a microprocessor or in a microprocessor socket. See
"Microprocessor problems" on page 186 for information about diagnosing microprocessor problems.
v If the blade server hangs on a POST checkpoint, see "POST progress codes (checkpoints)" on page 97.
If the blade server is halted and no error message is displayed, see "Troubleshooting tables" on page
183 and "Solving undetermined problems" on page 223.
v For intermittent problems, check the management-module event log and "POST progress codes
(checkpoints)" on page 97.
