If you have upgraded to Symantec Storage Foundation for Windows from an earlier versions of SFW or a related program (such as Microsoft Disk Management) and have existing dynamic disk groups that you created on your system, you most likely will want to upgrade those dynamic disk groups so that they are compatible with the dynamic disk group capabilities of Symantec Storage Foundation for Windows.

Note:

When a legacy disk group with dirty region logging (DRL) logs in its volumes is upgraded, the DRL logs are deleted on upgrade. You need to add the DRL logs manually after the upgrade.

Please note that the following features and operations are introduced with the new disk group version and, therefore, will not be supported if the disk group version is not upgraded:

The snapshot feature (prepare, snap shot, snap back, snap abort, and snap clear operations)
The dirty region logging (DRL) feature (add a log and remove a log operations)
Fast Resync and Fast File Resync features for volumes (add a log and remove a log operations)
Import disk group (import a legacy disk group as a shared disk group operation)
SSD caching

Note:

Once a disk group version is upgraded, it cannot be changed back to an earlier disk group version and you will not be able to import it on another server that is running any earlier versions of SFW.

Note:

Microsoft Disk Management Disk Groups do not support upgrading the disk group version. However, On Windows Server 2008 R2 and 2010, you can first convert the disk group to an SFW dynamic disk group, and then upgrade the SFW dynamic disk group.

You can also use the vxdg command to upgrade a disk group to the current SFW disk group version. The command line has the additional capability of upgrading a disk group created in Microsoft Disk Management.

Note:

After upgrading the disk group to the latest version and importing a disk group as a cluster-shared disk group (CSDG), you need to manually create the Volume Manager Shared Volume resource for each volume in a disk group. To do this,

To upgrade a dynamic disk group version:

In the tree view, right-click the disk group you want to upgrade and select Upgrade Dynamic Disk Group Version from the disk group context menu.
A confirmation screen appears with the text "Are you sure you want to upgrade the dynamic disk group?"
Click Yes to upgrade the dynamic disk group.
