Configure a Sun Cluster resource for the N1 Grid Service Provisioning System Remote Agent for raw and ssl communication only. The Master Server will start and stop the Remote Agent on every connection, as long as the Remote agent is configured for ssh communication. In this case, there is no Sun Cluster resource needed. In the ssh scenario, you have to install the N1 Grid Service Provisioning System Remote Agent on the shared storage and copy the ssh keys from one node to the remaining nodes of the cluster. This assures that all the cluster nodes have the same ssh personality.
There is no need to copy ssh keys in failover zone configurations.
