I'm not entirely sure I understand your questions - but, in a nutshell, the agent is not cluster-aware: to cover both nodes of a cluster you need to install an agent on each node. They get reported to ePO as two separate machines and treated as individuals.
Hi Joe Bidgood,
Honestly, I did not know exactly how to phrase my questions either.
Howerver, your reply is clear, being that ePO treats each client individually regardless of a single machine or part of a cluster.
Thanks very much Joe (yep, Joe Bidgood!).
