 
    RSX11M BL3.2 supports multiple mounts/dismounts.  If a disk is set
 as a PUBLIC device (SET /PUB=DDn:) prior to mounting, any user can
 use it.  If the disk is not set to be public prior to mounting, then
 each user must mount each disk prior to using it.  At any time a user
 may dismount a volume he/she has mounted.  DMO will return a message
 saying that the volume is dismounted.

 THIS DOES NOT MEAN THE VOLUME IS DISMOUNTED!

  This is because other users may still have the volume mounted.  If
 the dismount message includes the words 'FINAL DISMOUNT' and the
 console device prints the DISMOUNT COMPLETE message, then
 and only then is the dismount complete.

 A user may dismount all volumes he/she mounted by using the DMO /USER
 command (no disk need be specified) or individually via the DMO DDn:
 command.
 To dismount a device mounted by another user or marked as a
 public device, the user must be privileged and issue a DMO DDn:/DEV.
