completely. Multipath is working, when I run multipath -ll it shows me the
correct active path and it is mapped to a device under /dev/mapper. However, if
I try to access the device from that path, no luck. A mount request just hangs
and eventually there's a kernel error message.

parameters, it's still not working.

Check the archives, there was someone who posted their multipathd config for an
MD3000i a month ago which should be applicable (with a vendor/model name
change).
