System Resets During a Crash Dump Due to Watchdog Timer
JAG
JAGae79790
Description
During a crash dump of a virtual partition, hardware heartbeats are
delayed long enough such that the watchdog timer is triggered. If the
watchdog timer has been configured to reset, then the entire system is reset
(TOC).
Symptoms
A system (or nPartition) is reset when a virtual partition is performing a
crash dump.
Workaround
From the GSP, use the AR command to set the watchdog timer to not
automatically restart the system (or nPartition). Examples are below.
On non-nPartition-able servers, use the following procedure:
GSP> ar
Current System restart settings:
Automatic System restart: Enabled
