I can also mount the LUNs when accessing them from their active controller path. When I throw multipath into the mix, it fails 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.

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).
