Failover Cluster Keep Alive

Has anyone modified a failover cluster file server keep alive settings to use the secondary Ethernet adaptor?

Basically you need a separate network (preferred) or subnet and the best bet is to have a different IP range.

You can put the that in as the heartbeat network.

There is two separate networks for the cluster failover, cluster network  1 and cluster network 2.  The issue is the keep-alive traffic is using cluster network 1, is there a way to set them to use cluster network2?

I can't remember exactly where the location is. In the MS Cluster Administrator you can change the network preferences.

There's nothing in Cluster Administrator that adjusts the keep alives to use the secondary network.
 
The keep alives are using the default IP network 1; there's a default IP network 2. My thinking is this kind of modification would be a registry hack. Any ideas?

Though I don't know what other reprocusions you'd have as a result, if any, you could do this by:

1. In cluster administrator, make sure the cluster network is set to handle both internal cluster communication and client communication.
2. For the heartbeat network, ensure that it's set to only handle internal cluster communication.
3. In the computer's network settings, set your heartbeat network (with a small subnet and no default gateway) to be the primary network. (http://www.howtogeek.com/howto/27994/how-to-change-the-priority-of-wiredwireless-network-cards-in-windows/)

That way, you'd tell Windows to use the heartbeat network first, but it will skip over this network for general communications because the subnet mask will tell it that there's nothing on that network except the other cluster node, forcing it to use the public network adapter. Would that accomplish what you're looking for?
