How to remove a node from a cluster that is managed by SCVMM 2008 R2

The steps below demonstrate how to remove a node from a cluster that is managed by System Center Virtual Machine Manager 2008 (SCVMM).

In my example I have used a cluster named CLU224544 and I have 2 nodes.  Both are physical boxes with Windows Server 2008 R2 SP1 and the Hyper-V role installed.  It’s a CSV cluster and is managed by SCVMM 2008 R2:

If we want to remove the standalone host from SCVMM then we can do it from the SCVMM console via the Administration ->Managed Computers tab:

To remove the node, simply right-click and select Remove:

Now if we are managing a cluster then we won’t be able to remove a cluster node from here.  Even if you click "Remove" it will not remove the node.  In order to remove the cluster node you first need to Evict the node from the cluster.  You can do this from the cluster administration console as shown below:

Once you Evict the node from the cluster you have two options:

1.  Go to the SCVMM console and refresh the host manually:

2. Wait for the automatic refresh to happen.

Either way, once the Refresh job is done you will see that the node is listed as a standalone host:
