Process Monitoring and Integrity
as valid recovery actions for cmd_hand. The default recovery action for cmd_hand process is 4
(failover and reboot) and that cannot be changed to anything else. A recovery action of 1 (No
Action) is also not allowed because of the severity of the process.
In the event that cmd_hand process terminates unexpectedly, and the default recovery action kicks
in, there is 2-3 minute delay before the CMM actually reboots. This is normal and expected
because PMS makes multiple tries to failover, and times out because cmd_hand does not respond.

Note: PmsProc054 represents a crucial process of the CMM software stack. This process cannot be
restarted properly if it terminates unexpectedly. Hence, none of the recovery actions that attempt to
restart a process i.e., 2 (Restart) or 3 (Failover & Restart) are allowed as valid recovery actions for
BPM. The default recovery action for BPM process is 4 (failover and reboot) which can only be
changed to 1 (No Action).
