If there is a failure with the database or one of the VMware Cloud Director nodes, you can recover your database cluster.

If a cell in the database high availability cluster fails, the cluster health status indicates what the failure is and how you can resolve the issue. For example, the Degraded cluster health indicates a failure with a standby cell. A system administrator must redeploy the failed cell.

Figure 1. Recover from a Standby Cell Failure
The diagram displays a Healthy cluster. After a standby cell failure, the cluster health changes to Degraded. After a system administrator redeploys the failed standby cell, the cluster health changes back to Healthy.

If a primary cell in the database high availability cluster fails, the cluster health can change to No_Active_Primary, which indicates that a system administrator must repair the failed primary cell.
