A problem occurs only occasionally
and is difficult to diagnose. |
- Make sure that:
- All cables and cords are connected securely to the rear of the
server and attached devices.
- When the server is turned on, air is flowing from the fan grille.
If there is no airflow, the fan is not working. This can cause the
server to overheat and shut down.
- Check the system-error log or IMM system event log (see Event logs).
|
The server resets (restarts) occasionally. |
- If the reset occurs during POST and the POST watchdog timer is
enabled (click in the Setup utility to see
the POST watchdog setting), make sure that sufficient time is allowed
in the watchdog timeout value (POST Watchdog Timer).
If the server continues to reset during POST, see POST error codes and Diagnostic messages.
- If the reset occurs after the operating system starts, disable
any automatic server restart (ASR) utilities, such as the IBM Automatic
Server Restart IPMI Application for Windows, or any ASR devices that
are be installed.
Note: ASR utilities operate as operating-system
utilities and are related to the IPMI device driver. If the reset
continues to occur after the operating system starts, the operating
system might have a problem; see Software problems.
- If neither condition applies, check the system-error log or IMM
system-event log (see Event logs).
