Unable to Delete Offline VMFS Volume: Storage I/O Control Removal Error

Environment: 20 servers, VMWare Farm, v5.0.

2TB Fibre attached LUN mapped to all hosts in the cluster as VMFS3.  LUN was destroyed.  It was not (as seen below) under the storage control pool "Production Disk". Need to remove this dead volume so I can add a copy of the volume back with the same name.

Right click Volume -> Delete


Call "HostDatastoreSystem.RemoveDatastore" for object "datastoreSystem-606" on vCenter Server "" failed.
Cannot remove datastore 'vmfs3' because Storage I/O Control is enabled on it. Correct it and re-try the operation


Google gets hits on NFS versions ( ) of this removal process but no "properties" option can be accessed with the volume offline. So their is no way to remove it from Storage I/O control.

Tried to SSH into the system directly and as noted in entries related to this error, force unmount and removal of the volume.

Question: What is the process to unbind this volume from Storage Control and then remove it?

Stupid Question:

Is it possible to put one of the hosts in maintenance mode and reboot it to see what happens?

Maybe look over this post:
