dm mpath: rdac
This patch supports LSI/Engenio devices in RDAC mode. Like dm-emc it requires userspace support. In your multipath.conf file you must have: path_checker rdac hardware_handler "1 rdac" prio_callout "/sbin/mpath_prio_tpc /dev/%n" And you also then must have a updated multipath tools release which has rdac support.
