HI,

We want to swap out the heartbeat cable on a Windows 2003 cluster. What is the best way to do this without the server failing over?

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]

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?

it's right that the heartbeat cable used to tell the cluter when one of the nodes is gone
but the cluster setting alow you to use also to public network to send and recieve heartbeat data
so if the dedicated heartbeat cable fail or removed the cluster will not fail over.

the article i posted tell you how to configure the public network as "backup" heartbeat.
