Abstract
A method and device for storing and using information associated with multiple logical volumes stored on a single physical volume associated with a data storage system. The invention uses writable labels to read and write metadata associated with the multiple logical volumes. Metadata stored on a writable label associated with each physical volume is available without either reading the physical volume itself or accessing a host computer's control data set.
