In theory -- #2 except they shouldn't restart heartbeat, one of them should stop the resources. In practice one of the interesting things that happen when the comms come back is you have a duplicate ip address (vip) on your network. That's not something you want to happen, so you better make sure one of the nodes is down before you restore the comms.
