There are two Clustered Hyper-V Hosts (nodes), each protected by a separate UPS. PowerChute is installed on each host in the cluster. VM Migration is enabled.
UPS #1 has been running on Battery power for X number of seconds.
PowerChute issues a command to turn off UPS #1 and UPS turnoff starts.
PowerChute suspends that cluster node.
PowerChute migrates VMs to the other Host in the cluster, if VM Migration is enabled.
After the migration duration elapses, PowerChute shuts down any powered on VMs on Host A.
PowerChute executes the shutdown command file after the VM shutdown duration elapses.
When the shutdown command file duration has elapsed the OS shutdown sequence starts.
Following the Low Battery/Maximum required delay, Non-configurable 2 minute delay and Shutdown delay, UPS #1 gracefully turns off.
