Doh, forget the complicated junk below. I forget about the easier workaround. You can just do dm-multipath over iscsi, but with one path You would do the initial root session using the default routing and iface, and use dm-multipath over that, and then root on the dm multipath device over iscsi.
Then when you are booted and the init scripts run, the iscsi and iscsid init scripts would log into the session using the iface you had setup. dm-multipath/multipathd would then add that path to the root dm-multipath dev being used. And then you would just need to logout of the boot session by doing iscsiadm -m node -I default -T iqn.1992-08.com.netapp:sn.15333 -p 192.168.1.12:3260,2000 -u You could just write a script to automate that.
