Step 2: Copy the clhosts.client file onto client nodes
During the verification phase during initial cluster synchronization, PowerHA® SystemMirror® creates and populates a clhosts.client file on all PowerHA SystemMirror servers.
Copy this /usr/es/sbin/cluster/etc/clhosts.client file from a PowerHA SystemMirror server node to all client nodes, renaming it clhosts, removing the .client extension.
