The storage system is capable of simply and promptly changing the operation of a storage subsystem between operating as a stand-alone system and virtualize the plurality of storage subsystems logically into one virtual storage subsystem and execute a first mode of causing a host system to recognize the virtual storage subsystem. The storage is further able to execute a second mode of causing the host system to recognize the plurality of storage subsystems respectively as separate storage subsystems.
