Determining VxVM Disk Group Version

All Veritas Volume Manager disk groups have an associated version number. 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 work only on disk groups with the current disk group version, so you need to upgrade existing disk groups before you can perform the tasks. When you upgrade from a previous release, you can import disk groups that were created with a supported disk group.

For example, VxVM 5.1 SP1 supports all disk group versions that VxVM 4.1 supported (90 and 120). Consequently, all disk groups that were created using VxVM 4.1 can be imported after upgrading to VxVM 5.1 SP1.

The default disk group version for VxVM 5.1 SP1 is version 160. VxVM 5.1 SP1 supports disk groups with certain earlier versions. However, some new features for VxVM 5.1 SP1 require the latest disk group version. VxVM supports shared disk groups only on disk group version 140 or later.

Table 12 summarizes the disk group versions that correspond to each VxVM release on HP-UX from 3.0 to the current version.
