Upgrading the disk group version separately

If you plan to implement Veritas FastResync and Database FlashSnap, you must use Disk Group Version 90 or later, which is supported in Veritas Volume Manager 3.2 and higher. However, if you choose to retain a version of Veritas Volume Manager older than 3.2, which does not contain Disk Group Version 90 or later, upgrade your disk group version separately. The latest Disk Group Version is 140.

  Note   You cannot return to an older disk group version once you have upgraded.

 To determine which disk group version you are using

Use the vxdg list command as follows:

# vxdg -q list diskgroup | grep version

where the -q option means no header is printed describing output fields.

Example

To determine the disk group version on PRODdg:

# vxdg -q list PRODdg | grep version

  version: 90

 To upgrade the disk group version

Use the vxdg upgrade command as follows:

# vxdg -T diskgroup_version upgrade diskgroup

where the -T option means upgrading the disk group to a specific version.

For example, to upgrade the disk group to version 140 on PRODdg:

# vxdg -T 140 upgrade PRODdg
