If Host Maintenance Mode is enabled, PowerChute will command SCVMM to start a maintenance mode task on the managed hosts when a critical UPS event occurs. Host Maintenance is enabled by default.
When a host is placed into Maintenance mode SCVMM can:
PowerChute will leverage the Maintenance mode command by attempting to first move virtual machines to other hosts in the cluster. If this is not successful, PowerChute will use the Maintenance mode command to place all running virtual machines in a saved state. Maintenance Mode Duration represents the amount of time that PowerChute will wait before proceeding with the rest of the shutdown sequence. The PowerChute Maintenance Mode option is configured in Virtualization settings.

The Virtualization settings can be applied to all UPS Setups that have associated hosts. |

|
When hosts are taken out of Maintenance Mode, SCVMM does not re-start the Virtual Machines automatically, or fail them back to the original host if they were migrated. The Virtual Machines must be started manually, through SCVMM. |
In SCVMM, Possible Owners of a VM can be set in Virtual Machine Settings for each individual VM:
Possible Owners are the nodes to which a Virtual Machine can migrate, in the event of a maintenance mode task initiating migration of VMs. To prevent a VM from migrating to a particular host, clear the checkbox in the Possible Owners list associated with that host.
