/PRIORITY=n DSAn:

    Note: Do not include any HBMM-specific qualifiers in a command
    with this qualifier; doing so causes the command to fail.

    Overrides the current default priority setting. Priorities range
    from 0 (lowest) to 10000 (highest). The default priority is 5000.
    A shadow set with a priority of 0 is never considered for a merge
    or a copy on the system.

    When a recovery operation (that is, either a merge or a copy) is
    needed on multiple shadow sets, the shadow sets are recovered in
    priority order from highest to lowest. The priority setting is
    system specific; any change in priority made on a single system
    does not propagate to the entire cluster and does not persist
    across a system reboot.

    Once this qualifier has been applied to a virtual unit that is
    mounted, the setting persists across any subsequent DISMOUNT and
    MOUNT commands.
