Johnny, My understanding of resource groups is rather weak, so I can't give you a direct answer to your question; I'm sure others on this forum will be able to. But I can point you to additional information that might have the information you are looking for. The majority of information about resource groups, resources, and resource types is in the Sun Cluster Data Services Planning and Administration Guide:
http://docs.sun.com/app/docs/doc/820-4682 A section that probably addresses your questions is "Distributing Online Resource Groups Among Cluster Nodes": http://docs.sun.com/app/docs/doc/820-4682/ch14_resources_admin-35?a=view Hope this helps.
