Each member of a Failover Manager cluster maintains a cluster members file. The file contains the IP address and port number of the current members of the cluster. The Failover Manager installer creates a file template for the cluster members file named efm.nodes.in in the /etc/efm-2.0 directory. After completing the Failover Manager installation, you must make a working copy of the template.
For example, the following command copies the efm.nodes.in file, creating a file named efm.nodes that resides in the same directory:
# cp /etc/efm-2.0/efm.nodes.in /etc/efm-2.0/efm.nodes
Please note: By default, Failover Manager expects the cluster members file to be named efm.nodes. If you name the cluster members file something other than efm.nodes, you must modify the service script (efm-2.0) to instruct Failover Manager to use a different name.
Each node must be listed in an address:port format, separated by white space.
When you start an agent on a new node, the existing agents will update the cluster members files to include the address of the new node.
