Use the light path diagnostics to diagnose system errors quickly. See
“Diagnosing problems using the light path diagnostics feature” on page 27 for
more information.
POST error logs
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options that are installed in the blade server.
This series of tests is called the power-on self-test, or POST.
If POST finishes without detecting any problems, the first screen of the operating
system or application program appears.
If POST detects a problem, one or more beeps sound, and an error message
appears on the screen. See “Beep codes” on page 77 and “POST error codes” on
page 79 for more information.
Notes:
1. If a power-on password is set, you must type the password and press Enter,
when prompted, before POST will continue.
2. 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.
Viewing the System Event Log (SEL)
The System Setup Utility (SSU) is used to view the System Event Log (SEL)
records. Running the ssu.bat file provided on the SSU media invokes the SSU
environment by running the Application Framework (AF). If the system starts up
directly from the SSU media, this batch file starts automatically. If the system starts
up from a different media, the SSU can be started manually. When started in local
execution mode (the default mode), the SSU accepts user input from the keyboard
and or mouse and presents a graphical user interface (GUI) on the primary monitor.
The SSU can run on writable or non-writable, removable or non-removable media.
However, if the SSU media is non-writable, any user preference changes will be lost
when you exit the utility. This includes any changes made to color, operating mode,
language, and any other options that may be available from the various modules
included with the SSU.
The SSU automatically launches the SEL Manager after initializing the main window
of the AF.
The SEL Manager Add-In provides services to view the SEL stored on the server
management storage device of a server. The SEL Manager provides support to
perform the following functions:
v
Examine all SEL entries stored in the non-volatile storage area of the server.
