Using the Duration field, you must allow sufficient time for all your AFS VMs to gracefully shut down. If the AFS VMs are not shut down, this may prevent the Cluster and Controller VMs from shutting down.
The AFS Shutdown checkbox is selected by default, and this option should be left selected to allow graceful Cluster shutdown. In the event of a shutdown, PowerChute stops the AFS service, which shuts down the AFS VMs. This step occurs after the User VMs are gracefully shut down.
The Shutdown Duration field is the time allowed for the AFS service and VMs to gracefully shut down and start up following a UPS critical event.

If vCenter Server is unavailable during shutdown, an alternative shutdown process is used. In this case, PowerChute Network Shutdown must be configured with passwords for CVMs as SSH keys cannot be used to connect to AFS VMs. AFS VMs must have the same password as CVMs to permit the alternative shutdown process. |
AFS Shutdown/Startup
Selecting the AFS Startup checkbox re-starts any AFS VMs that were shut down when a UPS critical event has been resolved and the Nutanix Hosts are powered on.
If the AFS VMs are in the process of being started when a critical event occurs, PowerChute waits for the Startup Duration time to elapse before shutting down the VMs. This is to ensure that the VMs are shut down gracefully.
