vxdg -g<DynamicDiskGroupName> [-T <version>] upgrade

Upgrades a dynamic disk group that was originally created on an earlier version of Volume Manager or its related programs to the current Storage Foundation for Windows dynamic disk group version. The optional -T <version> parameter lets you upgrade a disk group that was created under Disk Management or earlier versions of Volume Manager for Windows to the Volume Manager disk group version.

In most cases, you'll want to upgrade an existing disk group so that it can take advantage of the dynamic disk group capabilities of Storage Foundation for Windows.

If you don't plan to make changes to these existing disk groups, you do not have to upgrade them; upgrading them lets you use additional features that affect a disk group, such as SFW's support for VSS, the Volume Shadow Copy Service feature. SFW incorporates VSS support into FlashSnap. If you plan to use the FlashSnap option with these existing disk groups, then you should upgrade them to the current disk group type.

Note:

If you upgrade a disk group to SFW, you cannot import it on another server that is running earlier versions of Volume Manager or Disk Management. Once a disk group version is upgraded, it cannot be changed back to an earlier disk group version.

For information about the supported disk group versions,

Note:

SFW does not let you upgrade a dynamic disk group that contains a boot or system volume. It must remain at the Disk Management disk group version level to allow for the fact that the program could be uninstalled and that a system and boot disk group would become inaccessible if it were a higher disk group version.

Examples

vxdg -gDynDskGrp1 upgrade

This command upgrades Storage Foundation for Windows dynamic disk group DynDskGrp1 to the latest version.

vxdg -gDynDskGrp2 -T60 upgrade

This command upgrades Storage Foundation for Windows dynamic disk group DynDskGrp2 to the version 60.

vxdg -gDynDskGrp2 -TSFW upgrade

This command can be used to convert Microsoft Disk Management Disk Group into SFW dynamic disk group. Windows Disk Management does not manage a converted disk group. It is only accessible and managed by SFW. The conversion cannot be undone.

Note:

Converting a Microsoft Disk Management Disk Group that was created using iSCSI disks to an SFW dynamic disk group is currently not supported.

You need to complete the conversion procedure with the following:

Restart the server.
Import the converted disk group using the vxdg import command.

Specify the -C option in the command to clear the host ID.
If advanced disk group features are needed, upgrade the disk group version using the vxdg upgrade command.
