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

       /INCLUDE virtual-unit-name[:] /SHADOW=(physical-device-
       name[:][,...])
       /NOINCLUDE virtual-unit-name[:] /SHADOW=(physical-device-
       name[:][,...]) (default)

    Automatically reconstructs a former shadow set to the way it was
    before the shadow set was dissolved. This qualifier is applicable
    only if you have the volume shadowing option. Refer to Volume
    Shadowing for OpenVMS for additional information.

    The /INCLUDE qualifier automatically mounts and restores a
    shadow set to the way it was before a system failure. Supply
    the exact virtual-unit name that was used when the shadow set was
    originally mounted. Use the virtual-unit naming format DSAnnnn:.

    You must also include the /SHADOW qualifier and specify at least
    one of the disk devices from the original shadow set. Use the
    standard device-naming format $allocation-class$ddcu[:]. Omit the
    parentheses if you name only one device.

    The /INCLUDE qualifier is position independent; it can appear
    anywhere on the command line.

    The default qualifier is /NOINCLUDE.

    Example

    The following example shows how to create a shadow set wherein
    the software determines automatically the shadow set members that
    should be mounted. The /SHADOW qualifier ensures the correct copy
    operation for the two shadow set members. In this case, $1$DUA10
    is the more current volume and becomes the source of the copy
    operation to $1$DUA11.

    If the shadow set was properly dismounted and no write I/O
    requests remain outstanding, the shadow set devices are
    consistent and are added back without the need for a copy
    or merge operation. Otherwise, Volume Shadowing for OpenVMS
    automatically performs a copy or merge operation.

    $ MOUNT/INCLUDE DSA0: /SHADOW=$1$DUA10: SHADOWVOL
    %MOUNT-I-MOUNTED, SHADOWVOL mounted on DSA0:
    %MOUNT-I-SHDWMEMSUCC, _$1$DUA10: (MEMBER1) is now a valid member of
    the shadow set
    %MOUNT-I-SHDWMEMCOPY, _$1$DUA11: (MEMBER2) added to the shadow set
    with a copy operation
