To determine whether to create HAStorage or HAStoragePlus resources within a data service resource group, consider the following criteria.
Use HAStorage if you are using Sun Cluster 3.0 12/01 or earlier.
Use HAStoragePlus if you are using Sun Cluster 3.0 5/02 or Sun Cluster 3.1. (If you want to integrate any file system locally into a Sun Cluster configured for failover, you must upgrade to Sun Cluster 3.0 5/02 or Sun Cluster 3.1 and use the HAStoragePlus resource type. See Planning the Cluster File System Configuration for more information.)
