Upgrading a Disk Group

This procedure upgrades a disk group to the disk group version that is compatible with the current Volume Manager release. Some new features and tasks only work on disk groups with the current disk group version, so you must upgrade existing disk groups before you perform these tasks. However, after you upgrade a disk group, you cannot access that disk group from machines running earlier releases of the Volume Manager.

To determine if a disk group needs to be upgraded, select the disk group and open the Disk Group Properties window. The Version field of the Properties window indicates whether the disk group has been upgraded to the current disk group version.

To upgrade a disk group

1. Select the disk to be upgraded to the current version.

2. Choose Disks Groups > Upgrade (Selected menu) or Disk Group Upgrade (Command Launcher).

3. Complete the Upgrade Disk Group dialog box as follows:

   Disk Group(s):

   If the correct disk group name is not already displayed in this field, type the disk group's name or click Browse to select the disk group.

   When you have provided all necessary information in the dialog box, click OK.

   Notes:

   Disk groups created with earlier releases of the Volume Manager must be upgraded before they can take advantage of new features and tasks in the current release. If a disk group is upgraded to the current disk group version, you cannot import that disk group on a machine running an earlier Volume Manager release. Disk groups that must remain backward compatible with earlier releases of the Volume Manager should not be upgraded.
