Abstract
A new disk system is connected to a switch that has been already connected to a host and old disk system. At that time, the new disk system is assigned in advance a port ID of the same value as the port ID that has been assigned to the F—Port of the switch, so that the new disk system will not be recognized from host 101. The new disk system read the configuration information of the old disk system. Then, in the switch, physical port ID 602 of old disk system 103 and physical port ID 602 of new disk system 104 are exchanged. The new disk system constructs volumes corresponding to the logical volume numbers and sizes of those volumes in the old disk system, and stores data of the old disk system in the corresponding volumes.
