Question : Getting round-robin load balancing working with vSphere 4.0 cluster on EqualLogic PS4000X

I have a shiny new EqualLogic PS4000X and three Dell R710's bristling with NIC's.  I also have lots o' vSphere Exchange licenses so life is much better than before :)

I am a bit stuck on configuring round-robin load balancing between each ESX machine and the PS4000.

I have followed this document so far:
http://www.equallogic.com/resourcecenter/assetview.aspx?id=8453

Each host has two physical NIC's, each connected to a separate switch.  The two nic's are on a single vSwitch.  I have two VMK's per host/vSwitch.  Each VMK is associated with one physical NIC. I have mapped the software iscsi hba to each of the VMK's as follows:

esxcli swiscsi nic add -n vmk0 -d vmhba33

and

esxcli swiscsi nic add -n vmk1 -d vmhba33

I right-clicked on each volume and configured the path selection to be 'round robin (vmware)'.  However, only one path appears for each volume, and the Group Manager on the PS confirms that only the first NIC is connecting from each host.

I've been over the document a zillion times...what am I likely missing here?

I haven't gotten any answers to this, only questions about information that was in the original post.  Oh well.
