Viewing event logs without restarting the server
If the server is not hung, methods are available for you to view one or more event logs without restarting
the server.
If IPMItool is installed in the server, you can use it to view the system-event log. Most recent versions of
the Linux operating system come with a current version of IPMItool.
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 29. Methods for viewing event logs
Condition Action
The server is not hung and is connected to a network. 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. You can restart the server and press Del to start the Setup
Utility program and view the system-event log.
System event log
The system-event log contains messages of three types:
Information Information messages do not require action; they record significant system-level events,
such as when the server is started.
Warning Warning messages do not require immediate action; they indicate possible problems, such as
when the recommended maximum ambient temperature is exceeded.
Error Error messages might require action; they indicate system errors, such as when a fan is
not detected.
Each message contains date and time information, and it indicates the source of the message (POST).
Diagnostic LEDs on the front control panel
Identifying the diagnostic LEDs on the front control panel is a very important method for diagnosing server
problems. See “Front control panel” on page 12 for detailed information.
Onboard debug digitron
The onboard debug digitron helps trained service technicians to identify server problems. When you turn on
the server, the onboard debug digitron will display debug code on the screen.
