Stranded ISCSI Space on NetApp

If you delete a VM (ESXi 5) that attaches an ISCSI LUN, is there a way to figure out the volume or UUID of the space to get it back on the vFiler (NetApp)? Maybe a script that goes out and finds all UUIDs on all active servers? I have the list of all UUIDs in existence, some are stranded by virtue of the VM being gone.

Also, in general, can you see the UUID from the OS on a Windows server still attached to the LUN, e.g. using powershell?

No, not recover any data. Simply return space to available that is tied up with the VM that no longer exists in the vFiler.

Do you have any snapshots on the Netapp volume housing the LUN?  If you have one prior to the deletion we should be able to get the VM back.

Check if you have snapmanager for virtual infrastructure license, setting it up will provide a way to restore the VMs when this type of stuff happens.
