All Veritas Volume Manager disk groups have an associated version number. Each VxVM release supports a specific set of disk group versions. VxVM can import and perform tasks on disk groups with those versions. Some new features and tasks work only on disk groups with the current disk group version. Before you can perform the tasks or use the features, upgrade the existing disk groups.

For 7.1, the Veritas Volume Manager disk group version is different than in previous VxVM releases. Veritas recommends that you upgrade the disk group version if you upgraded from a previous VxVM release.

After upgrading to SF 7.1, you must upgrade any existing disk groups that are organized by ISP. Without the version upgrade, configuration query operations continue to work fine. However, configuration change operations will not function correctly.

For more information about ISP disk groups, refer to the Storage Foundation Administrator's Guide.

Use the following command to find the version of a disk group:

# vxdg list diskgroup

To upgrade a disk group to the current disk group version, use the following command:

# vxdg upgrade diskgroup

For more information about disk group versions, see the Storage Foundation Administrator's Guide.
