Re: [dm-devel] Sun StorageTek 2530 and dm?



You need to have a stanza similar to following one for your device
in /etc/multipath.conf
--------------------
devices {
        device {
                vendor                  "IBM"
                product                 "1815"
                path_grouping_policy    group_by_prio
                hardware_handler        "1 rdac"
                path_checker            rdac
                failback                immediate
                no_path_retry           queue
                prio_callout            "/sbin/mpath_prio_tpc /dev/%n"
        }
}
---------------------
