6.7.4Successful Failover/Reboot Recovery

In this scenario, PMS detects a process fault. The configured recovery action is: failover to the standby CMM and upon successfully executing the failover, reboot the now standby CMM. The recovery actions are successful.

6.7.5Failed Failover/Reboot Recovery, Non-Critical

In this scenario, PMS is running on the active CMM and detects a monitored process fault. The severity of the process is configured to a value that is not critical. The configured recovery action is: failover to the standby CMM and upon successfully executing the failover, reboot the now standby CMM. The failover recovery action is unsuccessful (standby is not available, etc.). The process being monitored is not of a critical severity and therefore the reboot of the CMM will not be performed.
