Heartbeat Configuration Files

Heartbeat uses three configuration files:

 /etc/ha.d/ha.cf 

Specifies how the heartbeat daemons on each system communicate with each other.

 /etc/ha.d/haresources 

Specifies which server should normally act as the primary server for a particular resource and which server should own the IP address that client computers will use to access the resource.

 /etc/ha.d/authkeys 

Specifies how the Heartbeat packets should be encrypted.

Note 

The ha in these scripts stands for high availability. (The name "haresources" is not related to bunny rabbits.)
