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 V3 system setup interface. Then, click
BMC Settings
➙
POST Watchdog Timer
.
2. If the reset occurs after the operating system starts, enter the operating system when the system
operates normally and set up operating system kernel dump process (Windows and Linux base
operating systems will be using different method). Enter the UEFI setup menus and disable the feature,
or disable it with the following OneCli command.
OneCli.exe config set SystemRecovery.RebootSystemOnNMI Disable --bmc
xcc_userid
PASSW0RD@
xcc_ipaddress
3. See the management controller event log to check for an event code that indicates a reboot. See “Event
logs” on page 400 for information about viewing the event log. If you are using Linux base operating
system, then capture all logs back to Lenovo support for further investigation.
