i believe someone from HP already stated in this list that md driver
(multipath) does not work with EVA, i guess do to issues with
preferred path.

i believe using the qlogic driver failover is a viable solutio, another
is purchasing securepath from HP. but i believe there were issues using
securepath and lvm together.

i don't know if that is supported by either hp or suse.

i do personallu prefer mdadm to mkraid.
