## Adding a New Cluster Node

When you add a new node to a cluster that is in a partnership, you must perform additional tasks on that node to make it an active participant in the Geographic Edition configuration.

## How to Add a New Node to a Cluster in a Partnership

Perform all steps from the new node.

1. Add the new node to the cluster.

   Follow procedures in Chapter 8, Adding and Removing a Node, in Oracle Solaris Cluster System Administration Guide.

2. Install Geographic Edition, data replication, and application software on the new node.

   - To install Geographic Edition software, see Oracle Solaris Cluster Geographic Edition Installation Guide.

   - To install data replication and application software, see the appropriate manual for the software that you use.

3. If the cluster with the new node is the primary for any activated protection groups, remove application resource groups from those protection groups.

   This step is necessary to avoid application downtime.

       # geopg remove-resource-group resourcegroup protectiongroup

4. Deactivate all protection groups that are active on this cluster locally.

       # geopg stop -e local protectiongroup

5. Stop the Geographic Edition infrastructure.

       # geoadm stop

6. Re-enable the Geographic Edition infrastructure.

   This action recreates each Geographic Edition resource group and adds all nodes in the cluster, including the new node, to the node list.

       # geoadm start

7. Reactivate the protection groups that you deactivated in Step 4.

       # geopg start -e local protectiongroup

8. Restore any application resource groups that you removed in Step 3.

       # geopg add-resource-group resourcegroup protectiongroup
