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 3.0 12/01 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.
