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 name with this command:

# vxdg list disk_group_name

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 disk_group_name

Unless a disk group version is specified, 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.

To see the current cluster protocol version, type:

# vxdctl support
