Upgrading a Dynamic Disk Group Version
NOTE This procedure is not to be confused with upgrading to a dynamic disk.
The Dynamic Disk Group Upgrade procedure upgrades a dynamic
disk group to the dynamic disk group version that is compatible with the
current VxVM release. Some new features and tasks only work on
dynamic disk groups with the current dynamic disk group version, so you
must upgrade existing dynamic disk groups before you perform these
tasks. However, after you upgrade a dynamic disk group, you cannot
access that dynamic disk group from machines running earlier releases
of VxVM that do not support a higher current disk group version.
To determine if a dynamic disk group needs to be upgraded, select the
dynamic disk group and open the Disk Group Properties window. The
Version field of the Properties window indicates whether the dynamic
disk group has been upgraded to the current dynamic disk group version.
To upgrade a dynamic disk group
Step 1. Select the disk group to be upgraded to the current version.
Step 2. Choose Actions > Upgrade Dynamic Disk Group Version.
Step 3. Confirm the upgrade by clicking OK.
NOTE
If you have dynamic disk groups created with earlier releases of
VxVM, these must be upgraded before they can take advantage of
new features and tasks in the current release.
If a dynamic disk group is upgraded to the current dynamic disk
group version, you cannot import that dynamic disk group on a
machine running an earlier VxVM release. Disk groups that must
remain backward compatible with earlier releases of VxVM must not
be upgraded.
