The issue was to do with SCVMM 2012 SP1 and not the cluster itself. Although, I couldn't run the cleanup node command in powershell by itself.

I'm trying to add a cluster node to a Windows Server 2012 cluster. This system was part of an old cluster that has since been destroyed and the system upgrade from 2008R2 to 2012. I cannot add the system to the cluster because I keep getting these errors on the node when I do so. Any idea on how to release the drive &quot;Unknown Device&quot;? I've already tried restarting, and adding and removing the Failover Cluster feature. The result is the same.<br />

Clustered disk with ID 'Unknown Device' was not released by the Partition Manager while destroying the cluster. The error code was '21'. Restarting the machine will ensure the disk is released by the Partition Manager.
