Abstract:
A method is used in managing active-active mapped logical volumes. A mapped logical volume is created. The mapped logical volume includes first and second mapped logical volumes. Ownership of the first mapped logical volume resides with a first storage processor of a storage system and ownership of the second mapped logical volume resides with a second storage processor of the storage system. The mapped logical volume is managed. An access to the mapped logical volume is provided to the first and second storage processors.
