Configure iSCSI failover with MPIO

Hi guys,
I'm hoping someone can help me out, i have read the guide to setting up iscsi failover but i'm confused how i set it up with MPIO.

My current setup is as follows:

San1
eth0 192.168.10.220 - volume replication nic
eth1 192.168.11.220 - MPIO Nic1
eth2 192.168.12.220 - MPIO Nic2
eth3 192.168.13.220 - MPIO Nic3
Bond0 10.0.0.21 - Web access

San2
eth0 192.168.10.221 - volume replication nic
eth1 192.168.11.221 - MPIO Nic1
eth2 192.168.12.221 - MPIO Nic2
eth3 192.168.13.221 - MPIO Nic3
Bond0 10.0.0.31 - Web access

Syncronous volume replication is setup and appears to working fine

So my questions are which addresses do i use for the primary/secondary IPs in the setup also the auxiliary connection?

do i need to add virtual addresses to all the MPIO nics and connect iscsi initiator to that address? thanks guys!!

MPIO needs only 2 NIC (our 4 if you are bonding) and VIP to be set for each then select which Primary Node NIC that you wish to use or the 10.x.x.x NIC.

Details on how this is done from the link below.
