If you experienced a failover to the HA Only node, it is important to make sure the Standalone node becomes the active server again when it is restored. If the HA Only node remains the active server for more than 30 days continuously, the license on the HA Only node will become deactivated. To avoid license deactivation when the Standalone node is restored, change it to the active Server. If the Standalone node is unrecoverable, you can make the HA Only node a Standalone node.
