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

Use the following command to determine the version of a disk group:
# vxdg list diskgroup
To upgrade a disk group to version 140, use the following command:
# vxdg upgrade diskgroup
Upgrading from VxVM 4.1 on HP-UX 11i v3 to VxVM 5.0 on HP-UX 11i
v3
Following are the guidelines that you must consider prior to upgrading to VxVM 5.0 on HP-UX
11i v3:
• Disk group version 120 is the default disk group version for VxVM 4.1, whereas disk group
version 140 is the default disk group version for VxVM 5.0.
• All disk group versions supported by VxVM 4.1 (90, 110 and 120) are also supported by
VxVM 5.0. Consequently, all the disk groups created using VxVM 4.1 can be imported after
upgrading to VxVM 5.0. Some new features and tasks work only on disk groups with the
current disk group versions. To use new features, the disk group versions need to be
upgraded.
• VxVM 5.0 on HP-UX 11i v3 supports shared disk groups only on disk group version 140.
