Upgrading Disk Group Versions

Chapter 4

Upgrading Disk Group Versions

All disk groups have a version number associated with them. Each VxVM release supports a specific

set of disk group versions and can import and perform tasks on disk groups with those versions. Some

new features and tasks only work on disk groups with the current disk group version, so you need to

upgrade existing disk groups before you can perform these tasks. The following table summarizes the

disk group versions that correspond to each VxVM release:

You can get a disk group version listing by specifying a disk group with this command:

# vxdg list diskgroup

You can also determine the disk group version by using the vxprint(1M) command with the -l format

option.

To upgrade a disk group, use the following command:

# vxdg [-T version] upgrade diskgroup

If a disk group version is not specified using the -T option, this command upgrades the disk group to

the highest version supported by the VxVM version on your system.

For shared disk groups, the latest disk group version is only supported by the latest cluster protocol

version. See “Upgrading Cluster Functionality” in the Volume Manager Administrator’s Guide for

more information on changing the cluster protocol version.
