Using the Shutdown Duration field, you must allow sufficient time for all your Controller VMs to gracefully shut down before the hosts are commanded to shut down.
A Controller Virtual Machine runs on each node in a Nutanix cluster and is responsible for managing the Nutanix Cluster services.
Controller VM Shutdown is enabled by default. In the PowerChute shutdown sequence, the Controller VM is shut down after all other VMs in the Cluster, and the Nutanix Cluster itself are shut down.
The Duration field is the time allowed for all the Controller VMs to gracefully shut down. If the Controller VMs are shut down before the Duration time, PowerChute waits until this time has elapsed before proceeding to the next step in the sequence.

Controller VM Shutdown/Startup
If HA is enabled in a VMware environment and the Controller VM Startup checkbox is selected, PowerChute will re-start the Controller VMs when the Nutanix Hosts are powered on. PowerChute first checks that the host is available.
If HA is disabled, the VMware Virtual Machine Shutdown/Startup feature should be used to re-start the Controller VMs when the hosts are powered on.

It is recommended to wait at least 5 minutes after Controller VM startup to ensure all services are running before re-starting the Cluster. You should account for this using the Startup Duration field. |
