Our storage team has been testing failover using pre-U2-beta dm-
multipath RPMs for the past 2-3 months and it works well.  All I can say
is give it a try and see if it works for you.  Primary storage is EMC
DMX frames.

I don't know if the dm-multipath in U2 fixed an issue with EMC Clariion
active/passive arrays, but it definitely works with active/active arrays
and all kinds of failures (yank cables on host or shut down path on
frame or in the middle of SAN).
