Add Controller Nodes to Your Deployment

You can scale out your deployment by adding more controller nodes.

Note: The following limitations apply to controller nodes:

• Ensure that you have sufficient resources before initiating a scale-out operation.
• Do not reduce the number of controller nodes in a deployment.
• Do not delete the controller nodes through vSphere as it can cause unexpected behavior. For details, see KB 82608.

Procedure

1. Log in to the Integrated OpenStack Manager web interface as the admin user.
2. In OpenStack Deployment, click the name of your deployment and open the Nodes tab.
3. Click Scale Out Controller Node.
4. Enter the desired number of controller nodes and click OK.

Results

The new controller nodes are created. Once the nodes are displayed in the table and their status has changed to Ready, they can be used as part of your deployment.
