How can I connect iSCSI SAN with XEN SERVER 5.0 using Seperate networks?

I am using Dell MD3000i as an iSCSI storage, which has it's own separate LAN. The Dell M600 blade servers with M1000e chassis that we are using have 4 network interfaces. I want to use 2 network interfaces out of 4 for iSCSI connectivity. But what I found was, I have no way of configuring the interfaces. I tried using the solution provided to question "Connecting XenServer to an iSCSI SAN using two separate LAN's" on experts-exchange itself. But when I reboot the server, the configuration simply vanishes. Please let me know as to how can i go about it?
I am not using DHCP. Configuration of xenbr2 looks as follows:

XEMANAGED=yes
DEVICE=xenbr2
ONBOOT=no
TYPE=Bridge
DELAY=0
STP=off
PIFDEV=eth2
BOOTPROTO=none
PEERDNS=n

First you should create a bonded network with the 2 nics's that you want to use for storageaccess.

You should then rightclick your Xenserver in the Xencenter and click "management interfaces".
There you should create a new interface (you could call it "storage"), and select the bonded network, you have created for storage.

Give this new storageinterface an appropriate ip-adress, etc. and you should be up and running.

The advantage of doing it this way is, that the Xenserver uses the nic's directly without the "Xen-layer", and that means
better performance.
