mount_point
    Required.
    Local device (and optional directory tree) on which to mount the
    remote NFS file system. Specify this mount point as one of the
    following:
    DNFSn:
    DNFSn:[dir.subdir]
    DNFSn:[dir.subdir]file
    where:
    n        Specifies the unit number. Specify a value from 0 to
             9999. Specifying 0 causes the client to choose the next
             available unit number. (It does not mount a device named
             DNFS0:.)
    [dir]    Specifies the directory to mount
    or       (up to eight subdirectories in addition to the [000000]
    [dir.subdir]ectory).
    file     Specifies the individual file to mount.
 volume_label
    Optional. Default: First 12 characters of the combined values
    of the /HOST and /PATH qualifiers. The default label is a
    combination of /HOST and /PATH with a dollar sign ($) separating
    the two.
    Specifies the Files-11 (ODS-2 or ODS-5) volume label to be
    associated with the remote path name.
    You can use this parameter to provide a unique volume label on
    a system where there is a label conflict. The client does the
    following:
    o  Accepts only the first 12 characters for all other entries.
    o  Applies volume_label only on the first mount of a particular
       disk.
    o  Ignores volume_label with subsequent mounts on that disk.
    HP recommends that if you use the SET FILE /STATISTICS command
    on a file mounted with DNFS, do not include any colons (:) in the
    volume_label.
 logical_name
    Optional. Default: None.
    Specifies the logical name associated with the volume.
    The client creates the following logical definitions, depending
    on what you specify:
    o  If you mount DNFSn:[000000], the client defines the logical
       name as DNFSn:
    o  If you mount DNFSn:[dir.dir], the client defines the logical
       name as DNFSn:[dir.dir.] The extra dot allows for relative
       directory specifications. If you issue the following command:
       $ SET DEFAULT logical:[subdir]
       The full default definition becomes:
       DNFSn:[dir.dir.subdir]
    The client places the logical name in the SYSTEM logical name
    table, unless you specify the /GROUP or /SHARE qualifier. The
    client deletes the logical name from the SYSTEM table when you
    dismount the volume. The process must have SYSNAM privilege to
    mount a system mount point. Without SYSNAM or GRPNAM privilege,
    the user must specify /SHARE for a JOB mount. (See the /SHARE
    qualifier for more information.)
