Maybe worth a try: "multipathd -k" (interactive mode), then "show config" (or
"multipath -t"). In the output I spot entries like this:
device {
vendor "IBM"
product "1722-600"
path_grouping_policy "group_by_prio"
path_checker "rdac"
features "1 queue_if_no_path"
hardware_handler "1 rdac"
prio "rdac"
failback "immediate"
no_path_retry "300"
}
The hardware handler should be named for your device. We use ALUA here, so I
cannot really help.
