[CentOS] Help setting up multipathing on CentOS 4.7 to an Equallogic iSCSI target

I'm trying to test out an Equallogic PS5500 with a server running CentOS 4.7

I can create a volume and mount it fine using the standard 
iscsi-initiator-utils tools.

The Equallogic box has 3 Gigabit interfaces and I would like to try to 
set up things so I can read/write from/to the volume using multiple NICs 
on the server i.e. get 200+ Mbyte/s access to the volume - I've had some 
  basic info from Equallogic (Dell) saying that I need to set up DM 
multipathing - however, the info I have starts by saying that I have to:

"Make sure the host can see multiple devices representing the same 
target volume"

However, I'm not sure how I get to this point i.e. how do I set up the 
Equallogic and/or server so that I can see a single volume over multiple 
network links?

Has anyone set up one of these Equallogic boxes in this way using 
CentOS4/RHEL4 ?
