Abstract
A method and apparatus for managing a plurality of logical volumes in a computer system, the computer system including a processor and a storage system coupled to the processor, the storage system including at least one storage device, the storage system storing the plurality of logical volumes on the at least one storage device. At least two of the plurality of logical volumes are combined in the storage system into a virtual volume that is presented to the processor as a single logical volume. The storage system also presents the processor with information that enables the processor to deconstruct the virtual volume into the at least two of the plurality of logical volumes. Another aspect is directed to a multi-path computer system including a processor, a storage system including at least one storage device to store Y logical volumes, and X paths coupling the processor to the storage system. The processor is capable of accessing each of the Y logical volumes through each of the X paths, and includes Z unique target address identifiers identifying the Y logical volumes, wherein Z is less than X times Y.
