I'm not familiar with this SAN, so can't suggest to you a better
device configuration snippet.
Google may help you out: search for your device type and
"multipath.conf". Alternately, if your vendor supports RHEL5 (I'm sure
they do), you could contact them and ask them to provide you with a
known good configuration.
Actually, a quick search yields this:

Which seems to have what you need (verify of course).
