3.3.5 How to Add a New Volume to an Existing Disk Device Group (VERITAS Volume Manager)

After adding the volume, you need to register the configuration change by using the procedure "3.3.9 How to Register Disk Group Configuration Changes (VERITAS Volume Manager)".

When you add a new volume to an existing VxVM disk device group, you need to perform the procedure from the primary node for the disk device group, and the disk device group must be online.

1. Become superuser on a node of the cluster.

2. Determine the primary node for the disk device group.

   # scstat -D

3. Determine if the disk device group is offline.

   • If no, proceed to Step 4.

   • If yes, bring the disk group online.

   # scswitch -z -D disk-device-group -h node

   -z -D disk-device-group

   Switches the specified device group.

   -h node

   Specifies the name of the node to switch the disk device group to.

4. From the primary node (the node currently mastering the disk device group), create the VxVM volume in the disk group.

   Refer to your VERITAS Volume Manager documentation for the procedure used to create the VxVM volume.

3.3.5.1 Where to Go From Here

The change to the VxVM disk group must be registered to update the global namespace. See "3.3.9 How to Register Disk Group Configuration Changes (VERITAS Volume Manager)".
