Format: UNBIND client-device

 Use this command to unbind a client device from a service name and deletes
 the device.  This command breaks any existing connections for the
 client device, and deletes it when all channels to the device have been
 deassigned.

 You cannot UNBIND a device that has been mounted.  Once a client device has
 been mounted, the VMS command DISMOUNT/UNLOAD will handle deleting the
 client device.  UNBIND handles the case where a device is not mounted, if for
 example the service name were entered incorrectly.

 For tape clients, this is the only way to break the network connection to
 the service and delete the unit.

 Available client devices are:

 	DADn:	- Disk client
 	MADn:	- Tape client
