From dd172d72addefd89795e819cc2cc3eb1b9d12a7f Mon Sep 17 00:00:00 2001 From: Chandra Seetharaman Date: Thu, 12 Jul 2007 17:30:05 +0100 Subject: 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.
