This example describes the sequence of events that would occur when a Main server in a multi-server architecture becomes isolated (see Define what Action Should be Taken when a Server Becomes Isolated). In this case, the network connection has been lost and ICMP polls have failed.
The network consists of a Hot-Standby Pair. Server A is the Main server and Server B is a Standby server.
The settings for both servers are as follows:
The sequence of events is as follows:
- The network connection is lost. Server A is isolated. Server A remains the Main server and Server B becomes a Main server so that it can function independently.
- The network connection is restored. There are now two Main servers.
- Arbitration takes place to determine which server will now be the Main server and which will be the Standby server (see Define the Server’s Arbitration Priority). If Server A were to win arbitration, Server A would remain the Main server and Server B would become the Standby server.
