Getting unused directories in Hyper-V ClusterStorage Volumes via PowerShell
Posted in Virtual Machine Manager, Windows Powershell | No Comment | 1,137 views | 15/08/2013 10:25

You may export and move a VM to another host or volume, or maybe you may delete a VM but configuration and VHD files may still exist on old location. In that case, you can use this script to find that old VM directories.

# Get Cluster Nodes

					$VirtualDisks = Get-VM -ComputerName $ClusterNode -Name $VM.Name | Get-VMHardDiskDrive

						if ($VirtualDisk.Path -like "$FullPath*")

$ClusterNodes should contain different Cluster’s only one nodes. Using with that node name, we can query other nodes too.
