If hyperconverged infrastructure (HCI) support is enabled, additional sections will appear in the Virtualization Settings screen. For more information see Hyperconverged Infrastructure Support.

vCenter Server VM Shutdown Duration is the shutdown duration given to the Virtual Machine on which vCenter Server is running. This is configurable and is set to 240 seconds by default.

If the PowerChute virtual appliance is deployed on a vSAN host, the Skip Maintenance Mode checkbox must be selected.

PowerChute will use the No Action flag when placing vSAN hosts into maintenance mode when all Hosts in the vSAN cluster are being shut down.

In an Advanced UPS configuration where each Host is protected by its own UPS or UPS group, if Fault Tolerance Threshold (FTT) support is enabled, PowerChute will use the Ensure Accessibility flag for maintenance mode if the FTT specified is less than the number of critical hosts in the cluster. For example, if FTT support is enabled and the FTT level is set to 1, in a 3-node cluster where only 1 host is impacted by a power outage, PowerChute will place that host into maintenance mode using the Ensure Accessibility flag. If the other hosts later encounter a power outage, they will be placed into maintenance mode using No Action.

• Ensure Accessibility - vSAN ensures that all accessible virtual machines on this host remain accessible.

• No Action - vSAN does not evacuate any data from the host. Virtual machines may become inaccessible . PowerChute uses the No Action flag when the entire cluster is being shut down, and it is expected that VMs become inaccessible until the UPS critical event is resolved and the hosts are taken out of maintenance mode.
