Well, you don't really NEED a LogicalHostname in a RG. So, i guess i am not understanding
the question.
Is there an application agent which demands to have a network resource in the RG? Sometimes
the VALIDATE method of such agents refuses to work if there is no network resource in
the RG.
If so, tell us a bit more about the application. Is this GDS based and generated by
Sun Cluster Agent Builder? The Agent Builder has a option of "non Network Aware", if you
select that while building you app, it ought to work without a network resource in the RG.
But maybe i should back up and ask the more basic question of exactly what is REQUIRING
you to create a LogicalHostname?
