How to Use VxVM

To use the VxVM software with Sun Cluster Support for Oracle Parallel Server/Real Application Clusters, perform the following tasks.

1. Obtain a license for the Volume Manager cluster feature in addition to the basic VxVM license.

   See your VxVM documentation for more information about VxVM licensing requirements.

   Caution –

   Failure to correctly install the license for the Volume Manager cluster feature might result in a panic when you install Oracle Parallel Server/Real Application Clusters support. Before you install the Oracle Parallel Server/Real Application Clusters packages, run the vxlicense -p check command to ensure that you have installed a valid license for the Volume Manager cluster feature.

2. Install and configure the VxVM software on the cluster nodes.

   See the VxVM appendix in the Sun Cluster 3.1 Software Installation Guide and the VxVM documentation for more information.

3. Use VERITAS commands to create a separate shared disk group for the Oracle Parallel Server/Real Application Clusters database to use (see your VxVM documentation for details on shared disk groups).

   Before you create the shared disk group, note the following points.

   • Do not register the shared disk group within the cluster.

   • Do not create any file systems in the shared disk group because only the raw data file will use this disk group.

   • Create volumes as the gen use type.

   • Disks that you add to the shared disk group must be directly attached to all of the cluster nodes.

   • Ensure that your VxVM license is current. If your license expires, the node will panic.
