Changing a Clusters heartbeat cable

I would think there should be no issue if the Corp connection is configured All Communications (mixed traffic).

As soon as I unplug the cable though isnt it going to think that one of the servers has gone off-line and try and fail over?

*************************
Recommended configuration for the private adapter in Windows 2000 and Windows 2003
1. Click Start, point to Settings, click Control Panel, and then double-click Network and Dial-up Connections.
2. On the Advanced menu, click Advanced Settings.
3. In the Connections box, make sure that your bindings are in the following order, and then click OK: • External public network
• Internal private network (Heartbeat)
• [Remote Access Connections]
*************************
read the article, if you configure you cluster like it say, you should diconnect the heartbeat saftly.
 

sorry, the wrong copy/paste  :)

this is what you need to make sure heartbeat will flow on public network:
***************************************
* Start Cluster Administrator.
* Click the cluster name at the root of Administrator. On the File menu, click Properties.
* On the Network Priority tab, verify that the private network is listed at the top. If it is not, use the Move Up
   button to increase its priority.
* Click the private network, and then click Properties.
* Click to select the Enable this network for cluster use check box.
* Click Internal cluster communications only (private Network).

Sorry I am confused now.

You've got Server A and Server B in a cluster. They have a public LAN connection aswell as a private cluster connection. I want to change the cable on the private connection i.e. the heartbeat.

As soon as I remove that heartcable cable isnt it going to think that one of the nodes is down and try and initiate a failover?
