3.3.5 How to Create a New Disk Group When Initializing Disks (VERITAS Volume Manager)

This procedure is only for initializing disks. If you are encapsulating disks, use the procedure "3.3.6 How to Create a New Disk Group When Encapsulating Disks (VERITAS Volume Manager)".

After adding the VxVM disk group, you need to register the disk device group.

1. Become superuser on any node of the cluster that is physically connected to the disks that make up the disk group being added.

2. Create the VxVM disk group and volume.

   Use your preferred method to create the disk group and volume.

   Note -

   If you are setting up a mirrored volume, use Dirty Region Logging (DRL) to decrease volume recovery time in the event of a node failure. However, DRL might decrease I/O throughput.

   See the VERITAS Volume Manager documentation for the procedures to complete this step.

   If you are installing Oracle Parallel Server, create shared VxVM disk groups using the cluster functionality of VxVM as described in the VERITAS Volume Manager Administrator's Reference Guide. Otherwise, create VxVM disk groups using the standard procedures documented in the VERITAS documentation.

3. Register the VxVM disk group as a Sun Cluster disk device group.

   See "3.3.10 How to Register a Disk Group as a Disk Device Group (VERITAS Volume Manager)".
