Have you tried using the device-mapper-multipath rpm that is distributed
with RHEL5? 

Also, the Hitachi DF500F is autoconfigured, so you shouldn't need a
devices section, and most of your blacklist section is included by
default.

Try the following for a /etc/multipath.conf
----

blacklist {
	devnode "^sda$"
}

defaults {
	polling_interval 120
}

----

And see if that works with the RHEL5 device-mapper-multipath rpm
