- The wrong path group is active in a
multipathmap that uses thehp_swhardware handler multipathmaps usinghp_swhardware handler may use the non-optimal controller for the active path group in RHELmultipathmaps usinghp_sw hardware_handlerandmpath_prio_hp_swprio_calloutmay failover to the non-preferred controller when created- All LUNs were initially distributed using the same (active) Data Path Module (DPM).
