Removing a Server from a Cluster

You can remove a standby server from a cluster at any time. You cannot remove the active server unless you first fail over control to another node.

When you remove a standby server from a cluster, it becomes active as a standalone server. This standalone server does not interfere with the cluster, because it has a different IP address than the active server, and the active server knows that it is no longer a cluster member if a failover occurs.

To remove a server from the cluster:

Click System in the navigation bar.
Click the Cluster tab to display the Cluster Setup page.
Select the server you want to remove in the list. The server appears highlighted.
Click Delete Server.
A dialog box asks you to confirm the deletion.
Click OK.
Vocera removes the highlighted server from the cluster list.
Click Save Changes to save the information on the Cluster Setup page.
Vocera removes the server from the cluster. The removed server becomes active as a standalone server.
If your organization uses Staff Assignment, update the cluster list in the Staff Assignment configuration file (app.config) on each standby node:
1. On each standby node, open the following file in a text editor:
  \vocera\data\applications\staffassignment\app.config
2. Edit the serverIP property to include the comma-separated list of IP addresses for the Vocera Voice Server cluster. Enter numeric IP addresses using dotted-decimal notation. Do not enter domain names.
3. Save your changes.

Note: You do not need to update the cluster list in the Staff Assignment configuration file on the active node. The serverIP property is updated automatically on the active node when someone logs into Staff Assignment.
