Adding a Resource Using a Server-Specific Deployment

To add the Apache Web server as a resource that uses a named server deployment, assume that you add the resource to a server pool that is, by definition, a sub-pool of the Generic server pool. You create server pools that are sub-pools of Generic using the crsctl add serverpool command. These server pools define the Generic server pool as their parent in the server pool attribute PARENT_POOLS. In addition, they include a list of server names in the SERVER_NAMES parameter to specify the servers that should be assigned to the respective pool. For example:

$ crsctl add serverpool myApache_sp -attr
  "PARENT_POOLS=Generic, SERVER_NAMES=host36 host37"

After you create the sub-pool, add the Apache Web server resource, as follows:

$ crsctl add resource myApache -type cluster_resource -attr
  "ACTION_SCRIPT=/opt/cluster/scripts/myapache.scr,
   PLACEMENT='restricted',
   SERVER_POOLS=myApache_sp,
   CHECK_INTERVAL='30',
   RESTART_ATTEMPTS='2',
   START_DEPENDENCIES='hard(appsvip)',
   STOP_DEPENDENCIES='hard(appsvip)'"

In addition, note that when adding a resource using a server-specific deployment, the server pools listed in the SERVER_POOLS resource parameter must be sub-pools under Generic.
