Library /sys$common/syshlp/helplib.hlb  —  MOUNT  Qualifiers  /CONFIRM
       /CONFIRM virtual-unit-name[:] /SHADOW=(physical-dev-
       name[:][,...])
       /NOCONFIRM virtual-unit-name[:] /SHADOW=(physical-dev-
       name[:][,...])

    Causes MOUNT to pause and request confirmation before performing
    a copy operation on the specified disk device. This qualifier is
    applicable only if you have the volume shadowing option. See the
    HP Volume Shadowing for OpenVMS for additional information.

    This qualifier controls whether MOUNT issues a request to confirm
    a full copy operation when mounting a shadow set. The /SHADOW
    qualifier must be used with the /CONFIRM qualifier. Use /CONFIRM
    to display the volume label and volume owner for any specified
    physical device that is a target for a copy operation. MOUNT
    stops before any copy operations occur and issues the following
    prompt:

    Allow FULL shadow copy on the above member(s)? [N]:

    If you respond Y or YES, the mount operation continues
    automatically with copy operations allowed. If you respond N,
    NO, <RETURN>, or <Ctrl/Z>, the command quits without mounting any
    of the specified volumes (including volumes that did not require
    copy operations). If you type a response other than those listed
    above, MOUNT reissues the prompt.

    The /CONFIRM qualifier is similar to /NOCOPY. Use /CONFIRM to
    mount shadow sets interactively; use /NOCOPY in the site-specific
    startup command procedure SYS$MANAGER:SYSTARTUP_VMS.COM.

    Example

    The following example shows how to use the /CONFIRM qualifier to
    check the status of potential shadow set members before any data
    is erased. The command instructs MOUNT to build a shadow set with
    the specified devices, and prompts for permission to perform a
    copy operation. The response of YES instructs MOUNT to mount the
    shadow set.

    $MOUNT/CONFIRM DSA0:/SHADOW=($200$DKA200:,$200$DKA300:,$200$DKA400:) X5OZCOPY
