To ensure smooth functioning of your environment in case the Primary Server fails, it is recommended to add Fallback and DR servers. Under normal circumstances, the Primary and Fallback servers are synced continuously. In case the Primary server fails, then control passes to the Fallback server. If both the Primary and Fallback server fail, control passes over to the Disaster Recovery (DR) server.
- Go to System → High Availability.
- Go to the Vault tab → Add node → Fill up the details → Select the System Role for the server as Primary/Fallback/DR.
- Ensure that the Active checkbox is ticked.
- Click on Save.
