Makes the volume available to other users with the same group
    number in their UICs as the user entering the MOUNT command.

    The logical name for the volume is placed in the group logical
    name table. You must have the user privilege GRPNAM to use the
    /GROUP qualifier.

    Note that if the volume is owned by a group other than yours,
    access may be denied because of the volume protection.

    The /GROUP qualifier is not valid for ISO 9660 volume sets.

    The /GROUP qualifier is incompatible with the
    /OVERRIDE=IDENTIFICATION, /SHARE, and /SYSTEM qualifiers.

    Examples

    The following command mounts and makes available on a group basis
    the volume set consisting of volumes labeled PAYVOL1, PAYVOL2,
    and PAYVOL3. The logical name PAY is assigned to the set; anyone
    wanting to access files on these volumes can refer to the set as
    PAY.

    $ MOUNT/GROUP DB1:, DB2:, DB3: PAYVOL1,PAYVOL2,PAYVOL3  PAY

    The following command adds the volume labeled PAYVOL4 to the
    existing volume set MASTER_PAY. The root volume for the volume
    set must be on line when you enter this command.

    $ MOUNT/GROUP/BIND=MASTER_PAY DB4: PAYVOL4
