### uses the OVM CLI to give an overview of the physcial disks known by the ovm manager, together with the WWID, size, ... information
### Can be executed from any host which has ssh (port 10000) access to the ovm manager
### When executed, the script will ask for the OVM hostname or ip address and for the admin password
