One resource is required for each Sun StorEdge QFS metadata server.
Which resource groups will you use for these resources?
You might use multiple file systems for database files and related files. For more information, see SPARC: Requirements for Using the Sun StorEdge QFS Shared File System.
If you are using Oracle 10g, Oracle CRS manage Real Application Clusters database instances. These database instances must be started only after all shared file systems are mounted. To meet this requirement, ensure that the file system that contains the Oracle CRS voting disk is mounted only after the file systems for other database files have been mounted. This behavior ensures that, when a node is booted, Oracle CRS are started only after all Sun StorEdge QFS file systems are mounted.
To enable Sun Cluster to mount the file systems in the required order, configure resource groups for the metadata servers of the file systems as follows:
Create the resources for the metadata servers in separate resource groups.
Set the resource group for the file system that contains the Oracle CRS voting disk to depend on the other resource groups.
