VMS Help MOUNT, Qualifiers, /OWNER_UIC  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /OWNER_UIC=uic

    Requests that the specified UIC be assigned ownership of the
    volume while it is mounted, overriding the ownership recorded
    on the volume. If you are mounting a volume using the /FOREIGN
    qualifier, requests an owner UIC other than your current UIC.

    The parameter, uic, specifies the user identification code (UIC)
    in the following format:

       [group,member]

    You must use brackets in the UIC specification. The group number
    is an octal number in the range 0 to 37776; the member number is
    an octal number in the range 0 to 177776.

    To use the /OWNER_UIC qualifier for a Files-11 volume, you must
    have the user privilege VOLPRO, or your UIC must match the UIC
    written on the volume.

    Example

    The following command mounts a disk device labeled WORK on DRA3
    and assigns an owner UIC of [016,360]:

    $ MOUNT/OWNER_UIC=[016,360] DRA3: WORK
