Yes, see above response to Eddie Wai

When using iscsi_tcp, we are basically leaving all iscsi settings to default
(whatever the iscsi and iscsid services default to.) The routing tricks I
was talking about are implemented in /etc/rc.local, like so:
. /etc/sysconfig/network-
eval `ipcalc -n -p $IPADDR $NETMASK`
ip route add $NETWORK/$PREFIX dev $DEVICE tab 2
ip rule add from $IPADDR/32 tab 2 priority 200

. /etc/sysconfig/network-scripts/ifcfg-eth3
eval `ipcalc -n -p $IPADDR $NETMASK`
ip route add $NETWORK/$PREFIX dev $DEVICE tab 3
ip rule add from $IPADDR/32 tab 3 priority 300

ip route flush cache

and in /etc/sysctl.conf, we added the following two lines:

These changes are intended to ensure that inbound traffic to a specific ethX
device is responded to out the same interface it was received on, instead of
the first route in the routing table, as well as to ensure that the ARP
requests are only responded to on the interface that the physical mac
address is on (with out the sysctl rules, eth3 will respond to arps for
eth2's mac).
