According to the present invention, the processes of finding, selecting and binding partners in the MiAN cluster system will be accelerated.

A storage system or data management and migration method enabling migration of an access destination for a host system without having to stop the transmission of data between the host system and storage apparatuses. The storage system includes: a host system that issues a data read/write request; an external storage apparatus that provides an external logical volume for storing the data; and a first storage apparatus that creates a first virtual logical volume. In this system, the host system makes a request to the first storage apparatus to map volume information composed of the management information for the external logical volume; in response to the mapping request, the first storage apparatus maps the volume information for the external logical volume onto the first virtual logical volume and sends the volume information for the external logical volume and first virtual logical volume to the host system; based on the volume information for the external logical volume sent from the first storage apparatus, the host system searches for any virtual logical volume having the same volume information as the volume information for the first virtual logical volume or external logical volume, and sets the virtual logical volume searched for in this search as an alternate volume for receiving requests to read/write data from/to the external logical volume.

When a memory card is inserted into a computer, a memory controller sends command information stored in a memory array to the computer. Then, the computer stores the command information received from the memory card into a RAM. The computer generates a command as needed on the basis of the stored command information and sends the generated command to the memory card. When the memory card receives the command from the computer, the memory controller analyzes the received command and performs it while making reference to command analysis information. This makes it possible to reduce a load accompanying the change and addition of commands in a semiconductor memory.
