Unregister a Running Standby Cell in a Database High Availability Cluster

If you want to use a node in another role, or if you want to remove it from the high availability cluster, you must unregister it.

For more information about the VMware Cloud Director Appliance API, see the VMware Cloud Director Appliance API documentation.

You can unregister the cell during the normal system operation.

Note: For the primary node to function normally, at least one standby node must always be running.

Procedure

1. To find the name of the standby node that you want to unregister, run the VMware Cloud Director Appliance API method NODES.
2. From one of the other nodes, run the VMware Cloud Director Appliance API method UNREGISTER.
   Where node-name is the name of the standby appliance that you want to remove.
3. To verify that the unregistered standby node no longer appears in the database high availability cluster, run the API method NODES.
