   Applies to: NFS client

   Format

     DISMOUNT  { mount_point | logical_name }

               [ /ALL ]

               [ /HOST=host ]

               [ /[NO]WAIT ]
 

2  Restrictions
   Dismounting a /SYSTEM mount requires SYSNAM privilege.

   Dismounting a /GROUP mount requires GRPNAM privilege.
 

2  Parameters
 

mount_point

   Required (if you omit logical_name and the /ALL qualifier).
   Default: None.

   DNFS device (and optional directory tree) required to dismount.
   Specify this mount point as one of the following:

    DNFSn:
    DNFSn:[dir.subdir]
    DNFSn:[dir.subdir]file

   where:

   n        Value from 1 to 9999.

   [dir]    Directory to mount
   or       (up to eight in addition to the [000000] directory).
   [dir.subdir]

   file     Individual file to dismount.

   If you use the /ALL qualifier, you must specify DNFSn: without
   the directory tree.
 

logical_name

   Required (if you omit mount_point and the /ALL qualifier).
   Default: None.

   Logical name that you defined with the MOUNT command of the
   device to dismount.
 

2  Qualifiers
 

/ALL

   Optional.

   Dismounts one of the following:

   o  All file systems from all servers: DISMOUNT /ALL

   o  All file systems on the specified server: DISMOUNT /ALL
      /HOST=host

   o  All file systems on the specified device: DISMOUNT DNFSn: /ALL

   If you dismount using the /ALL qualifier, the dismount operation
   completes even if the server is not currently reachable.
 

/HOST

      /HOST=host

   Optional. Default: None.

   Dismounts all file systems from the specified NFS server.

   Valid only with the /ALL qualifier.
 

/WAIT

      /WAIT
      /NOWAIT

   Optional. Default: /NOWAIT.

   o  /WAIT

      -  Does not dismount the mounted file system if outstanding
         activities exist.

      -  Waits until the dismount has been completed.

      -  If you try to access any files on the mount point, the
         dismount fails.

   o  /NOWAIT

      -  The client completes the command immediately.

      -  Dismounting does not actually occur until all file activity
         has been completed.
