[ovirt-users] iSCSI

[Dan Yasny]

Maybe it's an EMC thing? I know they always recommend using their own
multipathing client (aka powerpath), so you either need to make sure the
SAN accepts Linux multipath, and that EMC devices aren't blocked in your
multipath.conf

I remember Clariions used to require some explicit aLUA related settings,
should be easy enough to google or maybe call the SAN vendor
