A special situation occurs when the Main Server in normal operation (base and core services running) loses connection to the Standby Server for the reason of a broken network cable or a broken network interface card as an example. Then the Main Server will raise a “Standby server is not reachable” alarm and event (if configured). If the Standby Server is of type “Warm Standby Server” it will automatically start up its core services and raise a “Main server is not reachable” alarm and event (if configured). Once the connection problem is fixed and core services on both servers are still running, each server will raise a “Main server and standby server running both at the same time” alarm and event (if configured).
