The following table describes the methods that you can use to view the event logs,
depending on the condition of the server. The first two conditions generally do not
require that you restart the server.
Table 11. Methods for viewing event logs
Condition Action
The server is not hung and is connected to a
network.
Use any of the following methods:
v Run DSA Portable to view the event logs
or create an output file that you can send
to IBM service.
v In a web browser, type the IP address of
the IMM and go to the Event Log page.
v Use IPMItool to view the system-event
log.
The server is not hung and is not connected
to a network.
Use IPMItool locally to view the
system-event log.
The server is hung. v Restart the server and press F2 to start
DSA Preboot and view the event logs.
v Alternatively, you can restart the server
and press F1 to start the Setup utility and
view the POST event log or system-event
log. For more information, see “Viewing
event logs through the Setup utility” on
page 39.
Checkout procedures
This topic provides details about the checkout procedure used to diagnose
problems with the server.
The checkout procedure is the sequence of tasks that you should follow to
diagnose a problem in the server.
About the checkout procedure
This topic provides important safety and general information to review before you
perform the checkout procedure.
Before you perform the checkout procedure for diagnosing hardware problems,
review the following information:
v Read the safety information that begins with “Safety” on page v.
v IBM Dynamic System Analysis (DSA) provides the primary method of testing
the major components of the server, such as the microprocessor board, Ethernet
controller, DIMMs, memory controller, optical drives, and hard disk drives. You
can also use them to test some external devices. If you are not sure whether a
problem is caused by the hardware or by the software, you can use DSA to
confirm that the hardware is working correctly.
v When you run DSA, 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 DSA.
Exception: If multiple error codes or light path diagnostics LEDs indicate a
microprocessor error, the error might be in a microprocessor or in a
