Before you can set up a cluster you have to add your 'local'
applicationservers from the two nodes using the addNode-command. By default
all existing applicationservers will be added under cell-control by the
network deployment manager (WAS ND). Each server has a "full qualified name"
which beside the servername (e.g. the default server 'server1') consists of
the hostname. You can see this in the WAS ND-Adminconsole.

When building the cluster by using the WAS ND-Adminconsole the
clustermembers - which in your case should based on the
server1-configuration - can get completely different names (e.g.
Epiphany_cluster with clustermembers Epi_cm1, Epi_cm2 etc.). To make us of
the clustered appservers, you deploy your application to the cluster
Epiphany_cluster. This automatically deploys the application on all
clustermembers (don't forget updating httpPlugin when having
webressources)). You can now start the cluster or each clustermember
seperately.
When accessing EJBs, you switch from the 'node-view' to the 'cluster-view'.
You can see the ports in the Endpoint-Definition for each clustermember.

See WAS ND Admin guide.
