Hello Marc,

If you'd like to know which NIC did your boot, just run "route print,"
and you'll see a route specifically to your SAN, even if it's on the
same subnet.  The interface to which that route applies is your boot
NIC.

There might be some esoteric configs where this is incorrect, and it's
worth pointing out that you shouldn't have a default gateway on your
iSCSI NIC, but otherwise this should do the trick.

Cheers,
