3.2.2. Adding Unallocated Volumes to a Volume Group
Once initialized, a volume will be listed in the 'Unallocated Volumes' list. The figure below illustrates an unallocated partition (Partition 3). The respective buttons at the bottom of the window allow you to:

The figure below illustrates the logical view of 'VolGroup00' after adding the new volume group.
In the figure below, the uninitialized entities (partitions 3, 5, 6 and 7) were added to 'VolGroup00'.
