  (cid:2) Format volume: Controls whether the volume is formatted before being made available; 
  defaults to Enabled. 
  
  (cid:2) Cache mode: Controls volume caching; defaults to Enabled. Other available options are 
  Read-only and Disabled. 
  
  (cid:2) OpenVMS UDID: Each OpenVMS Fibre Channel-attached volume requires a user-defined
