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-nPartitionable servers, use the following procedure:
GSP> ar
Current System restart settings:
Automatic System restart: Enabled
