Description

   When you specify any of the following qualifiers, the operational
   status of the drive is changed: /ABORT_VIRTUAL_UNIT, /AVAILABLE,
   /COPY_SOURCE, /DUAL_PORT, /ENABLE, /ERROR_LOGGING, /FORCE_
   REMOVAL, /MEMBER_TIMEOUT, /MVTIMEOUT, /POLL, /READ_COST, /SITE,
   or /SWITCH.

   When you specify the /SPOOLED qualifier, program output that uses
   OpenVMS Record Management Services (RMS) or file control system
   (FCS) and that specifies the print device name is written onto
   an intermediate disk rather than written directly to the print
   device or terminal.
