You are supposed to have identical haresources files on both balancers.
So you have the _same_ node name in both files. This name determins the
master node.

Heartbeat should start the resources only on one host at a time.
If it does something different then there is a configuration error.

I'm not quite sure whether the IPaddr script can do this. But you can
use your on script. However, it is important that the first script after
the node name returns "running" or "stopped" if called with the
parameter "status"!
If you don't get it to work then please post your ha.rc and haresources
files from both hosts (if possible without all the comments).
