To add a node to an existing Microsoft cluster

1. Share the required disk volumes on the new node.

2. Use Cluster Administrator to add the node to the cluster.

3. If you are adding a new Enterprise Vault virtual server, prepare a new resource group and add the prerequisite resources.

4. Specify the new node as a possible owner of all resources in all the resource groups that are required to run on it.

5. Add the new node at a suitable position in the preferred owners list of any resource group that is required to run on it.

6. Install Enterprise Vault on the node.

7. Run the Enterprise Vault Configuration wizard and choose either Create a new Enterprise Vault server with Cluster support or Configure the node as a failover node for an existing clustered server, as required.

8. Test the modified cluster to confirm that failovers to or from the new node work as planned.
