PROBLEM TO BE SOLVED: To solve the following problem that a computer system has to be temporarily stopped when a switch (a virtualization switch) is introduced, since the port ID of virtual storage conventionally differs from that of a storage device assigned to the virtual storage when a switch for virtualizing storage is introduced to the computer system including a SAN, a host computer and the storage device. SOLUTION: The virtualization switch to be introduced to the computer system assigns the port ID to the port of the virtual storage generated by the virtual switch so as to allow the port ID to have a value being the same as that of the port ID of the existing storage device, and transmits an access request to the virtual storage when the port ID is designated as an access destination by an access request from one computer to the storage device.
