step 27 Adding Resource Group

Add Resource Groups:
smitty hacmp -> Extended Configuration -> Extended Resource Configuration ->
HACMP extended resource group configuration

Continue similarly for all the resource groups.
The node selected first while defining the resource group will be the primary owner of
that resource group. The node after that is secondary node.
Make sure you set primary node correctly for each resource group. Also set the failover/fallback policies as per the requirement of the setup
