Unregister-ClusteredScheduledTask Delete a clustered scheduled task
Set-ClusteredScheduledTask Update existing clustered task
Get-ClusteredScheduledTask Enumerating existing clustered tasks
Simplify host patching and repairs
Draining a node
• Node is paused preventing new groups from moving to that node
• All groups are issued a move
• VMs are queued up and live migrated off based on priority
Resuming a node
•Resume-ClusterNode –Failback invokes failback policies
to return groups to that node when it is brought out of
