VERITAS Volume Manager 4.1 Administrator's Guide

Creating and Administering Disk Groups
Upgrading a Disk Group
Chapter 4 193
To list the version of a disk group, use this command:
# vxdg list dgname
You can also determine the disk group version by using the vxprint
command with the -l format option.
To upgrade a disk group to the highest version supported by the release
of VxVM that is currently running, use this command:
# vxdg upgrade dgname
By default, VxVM creates a disk group of the highest version supported
by the release. For example, Volume Manager 4.1 creates disk groups
with version 120.
