Hello, I read over that thread. Once thing missing from that discussion is how Linux routing works with multiple NICs on the same subnet. If you have two NICs IP'd on same IP subnet, only one NIC will be active. That becomes the default NIC for that subnet. Down that interface and the other will become active. That's the default behavior. That's why the -I interface option or creating interfaces files is needed, not just for offload cards. On iSCSI SANs like the Equallogic where all interfaces are on the same subnet, the iSCSI initiator must initiate iSCSI connections from each interface desired for iSCSI traffic. iSCSI SANs like the MD and CML can use different network subnets to get around how Linux networking works.
