The ha.cf file is the HeartBeat main configuration file consisting of a configuration parameters list. A sample follows:
bcast eth1 keepalive 2 warntime 10 deadtime 30 initdead 120 udpport 694 nice_failback on node EY-FTP1 ## This is your server 1 node EY-FTP2 ## This is your server 2 ping 192.168.38.1 ## This is a pingable address
The “node” definitions allow HeartBeat to identify the two servers that form the High Availability cluster. The last entry is how HeartBeat confirms its network connectivity. If the “ping” fails to operate correctly, HeartBeat assumes that although it is functioning correctly, it has lost connectivity to the network. In this case, HeartBeat proceeds to interchange to the other node/server.
