Updating Networks

Data Management for VMware Tanzu allows you to update Application Networks and the Control Plane Network. You can add one or more Application Networks and change the default Application Network that is attached to the onboarded Agent, when required. You can also change the Control Plane Network that is attached to the onboarded Agent, when required. However, you can only remove an Application Network or Control Plane Network from an environment if none of the databases provisioned with that environment are using that network.

Note: While updating Application Networks and Control Plane Network, in-flight database operations use the existing configured networks. After the process of updating Application Networks and the Control Plane Network is completed, databases that are subsequently created use the newly configured networks.

Audience

These procedures are typically performed by an Organization Administrator or Provider Administrator.

Prerequisites

• Before you remove an Application Network or change a Control Plane Network that is configured, ensure that you delete the databases that are provisioned using these networks.
• Before you change a Control Plane Network, ensure that the Agent VM can access the new Control Plane Network that will be configured.

Procedure to Update Application Networks and Control Plane Network

Perform the following procedure to update the Application Networks and Control Plane Network:

1. Log in to the Data Management for VMware Tanzu console using your Organization Administrator or Provider Administrator credentials.

2. From the left navigation pane, select Environment.

   The Environment view table displays the currently onboarded environments.

3. Examine the environments listed in the table, identify the environment for which you want to update the network, and click that row.

   The environment information in the Details tab displays.

4. To update the configured Application Networks and Control Plane Network, click the EDIT button in the Environment Information section.

   The Environment Edit dialog box displays.

5. Click the Networks tab in left pane of the Environment Edit dialog box.

   The Networks form displays with the existing configuration pre-selected.

6. In the Application Network section, select one or more Application Network entries in the right pane and select one of the Application Network entries as Default.

7. In the Control Plane Network section, select a Control Plane Network in the right pane from the drop-down list.

8. Click UPDATE.

9. To validate the success of this operation, you can monitor the status in the Recent Operation pane.

Note: When the Application Networks and Control Plane Network of an Environment are updated, the existing Database Instances belonging to that environment are not updated with the network modifications. They continue to use the networks that were configured during their creation.
