A storage system includes a plurality of storage apparatuses respectively connected to a host apparatus via a network. A disk controller of each storage apparatus has DKC identifying information for recognizing itself, a logical device identifier created based thereon, and a virtual/logical device identifier set containing a real/logical device identifier and a virtual/logical device identifier. The storage apparatus defined with a pair relationship creates a virtual/logical device identifier set of a mirrored image relationship by replacing its own real/logical device identifier and using it as its own virtual/logical device identifier.
