Pretty much you don't configure the stand by lan card in /etc/rc.config.d/netconf and you configure it as a stand by in your serviceguard configuration.

One note: You need to check with network administration on your san settings. Its possible for them to do things on a switch that will interfere with the failover of the ip address.

Hi,

Also make sure you assign the 2nd lan card onto a different subnet and another router, in case you need full redundancy.

Gigabit ethernet is preferred for (private) interconnects.

I you don't need speed on the interconnect a simple cross-over cable or even 10base-T coax will do.
