If you use VxVM to set up shared disk groups for Oracle Parallel Server/Real Application Clusters, use the cluster functionality of VxVM as described in the VERITAS Volume Manager Administrator's Reference Guide. Differences between creating shared disk groups for Oracle Parallel Server/Real Application Clusters and creating other disk groups include the following items.
You must import the Oracle Parallel Server/Real Application Clusters shared disk groups by using vxdg -s.
You do not register the Oracle Parallel Server/Real Application Clusters shared disk groups with the cluster framework.
To create other VxVM disk groups, see How to Create a New Disk Group When Initializing Disks (VERITAS Volume Manager).
