Decide which storage management scheme to use:
VERITAS Volume Manager (VxVM) with the cluster feature
Hardware redundant array of independent disks (RAID) support
The cluster file system
If you use the cluster file system, decide which volume manager to use:
Solaris Volume Manager
VxVM without the cluster feature

Check with a Sun Enterprise Services representative for the current supported topologies for Sun Cluster Support for Oracle Parallel Server/Real Application Clusters, cluster interconnect, storage management scheme, and hardware configurations.
Ensure that you have installed all of the applicable software patches for the Solaris operating environment, Sun Cluster, Oracle, and your volume manager. If you need to install any Sun Cluster Support for Oracle Parallel Server/Real Application Clusters patches, you must apply these patches after you install the data service.
