6.3. Adding a segment manager to an existing disk

When you add a segment manager to a disk, the segment manager needs to change the basic layout of the disk. This change means that some sectors are reserved for metadata and the remaining sectors are made available for creating data disk segments. Metadata sectors are written to disk to save information needed by the segment manager; previous information found on the disk is lost. Before adding a segment manager to an existing disk, you must remove any existing volume management structures, including any previous segment manager.
