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 5.0.1 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 5.0.1.
The default disk group version for VxVM 5.0.1 is version 140. VxVM 5.0.1 supports disk groups
with certain earlier versions. However, some new features for VxVM 5.0.1 require the latest disk
group version. VxVM supports shared disk groups only on disk group version 140.
Table 12 summarizes the disk group versions that correspond to each VxVM release on HP-UX
from 3.0 to the current version.
