Check your listener.ora. For a start, unless the services are listed explicitly in the SID_LIST section, the agent doesn't know about them, and they won't be discovered. Second, make sure you've set up the init.ora for both nodes/instances so that automatic registration of the instances with their respective listeners works. Registration will require you use SERVICE_NAME= rather than SID= if you want to be able to connect to a single entity, the cluster... which you'll need for load balancing and failover purposes. Third, make sure each instance is registering itself correctly with the *remote* listeners (so, for #2, you need to set local_listener, and for #3, you need to set remote_listener).

In short, post your listener.ora, your init.ora and your tnsnames.ora if you want a fuller answer.
