If needed, you can modify the association of your volumes to your volume groups. For example, after you create a volume group you can move one or more logical volumes from an existing volume group to the new volume group.
As you assign LUNs
                    and possibly other volume groups to a selected volume group, Oracle FS System Manager (GUI) provides you with a preview of your selected change in the Volume Groups overview page.
