In Windows Server 2008 R2 it was not possible to move the Core Cluster Resources via Cluster Failover Manager (FCM). When performing maintenance on a cluster node, I prefer not only to evacuate all running guests on that node, but also the CSV disks which are owned by that node. If the Cluster Resource Group also resides on the node that is due for maintenance, one must resort to PowerShell to move that group somewhere else.
In a Windows Server 2012 cluster, the PowerShell commands are exactly the same as in Windows Server 2008 R2. If you don’t feel comfortable using PowerShell, you might be pleasantly surprised that this activity can now also be performed from the Failover Cluster Manager.
In FCM, right-click the Clustername, click on More Actions, Move Core Cluster Resources and select either Best Possible Node or select the node of your choice.
