MPDEV_ENABLE is a system parameter that 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.
