multiple IPs and DeviceExists in HA setup

Hi,

I know this is an FAQ, but I have a situation where the normal method
(bind monitoring templates directly to the server the app lives on)
doesn't work.

Say I have two servers, with a DRBD replicated volume. MySQL runs on
one, and the other monitors it with heartbeat. Should the first fail,
the IP used for MySQL moves along with daemon.

I can't add MySQL monitoring using the virtual IP, because Zenoss
detects it already exists on server #1. If I monitor MySQL directly on
server #1 and for some reason (purposeful or otherwise) MySQL is
suddenly running on server #2, then... fail. Suggestions?

-Charlie
