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.
