HACMP How to change from cascading to rotating resources.

Question:
  What are the steps to change from cascading to rotating resources.

Env:  AIX 3.2.5  HACMP 3.1

Response:

  Here are the steps required for converting from cascading to rotating
resources.  These steps assume that the service address from node A is
going to be the rotating IP address.

  1) Remove the resource group.
      smit hacmp
        Manage Node Environment
          Manage Resource Groups
            Add / Change / Show / Remove a Resource Group
              Remove a Resource Group

  2) Remove the service address of node B.
       smit hacmp
         Manage Cluster Environment
           Configure Adapters
             Remove an Adapter

  3) Remove the node name from the service address of node A.
       smit hacmp
        Manage Cluster Environment
           Configure Adapters
             Change / Show an Adapter
               \
                  Node Name                []

  4) Create a resource group with node A and B using rotating resources.
      smit hacmp
        Manage Node Environment
          Manage Resource Groups
            Add / Change / Show / Remove a Resource Group
              Add a Resource Group
                
  5) Add the highly available resources to the resource group.
      smit hacmp
        Manage Node Environment
          Manage Resource Groups
            Configure Resources for a Resource Group

  6) Sync the nodes.
      smit hacmp
        Manage Node Environment
          Sync Node Environment

      smit hacmp
        Manage Cluster Environment
          Synchronize all Cluster Nodes

  7) Change the IP address of the service/boot interface 
     back to the boot IP address on both nodes
      smit chinet

  8) Start HACMP on node A.
       smit clstart
  9) Start HACMP on node B.
       smit clstart
