Intermittent unexpected reboots
Note:
Some correctable errors require that the server reboot so that it can disable a device, such as a
memory DIMM or a processor to allow the machine to boot up properly.
1. If the reset occurs during POST and the POST watchdog timer is enabled, make sure that sufficient time
is allowed in the watchdog timeout value (POST Watchdog Timer).
To check the POST watchdog time, restart the server and press F1 to display the Lenovo XClarity
Provisioning Manager Lite system setup interface. Then, click

.
2. If the reset occurs after the operating system starts, disable any automatic server restart (ASR) utilities,
such as the Automatic Server Restart IPMI Application for Windows, or any ASR devices that are
installed.
3. See the management controller event log to check for an event code that indicates a reboot. See “Event
logs” on page 243 for information about viewing the event log.
