(Alpha and Integrity servers) MPDEV_ENABLE enables the formation
    of multipath sets when set to ON (1).  If MPDEV_ENABLE is set
    to OFF (0),  the formation of additional multipath sets and the
    addition of new paths to existing multipath sets are disabled.
    However, existing multipath sets remain in effect. The default is
    ON.

    MPDEV_REMOTE and MPDEV_AFB_INTVL have no effect when MPDEV_ENABLE
    is set to OFF.
