摘要：
A storage control system having no risk of changing the storage content of a logical volume by a data update to a virtual logical volume. A logical volume, which is not correspondent to a virtual logical volume, can be specified when defining a virtual logical volume correspondent to a logical volume. A first storage controller comprises a port capable of connecting to both a logical volume of the first storage controller, and a logical volume of a second storage controller; a virtual logical volume, which is set in association with a logical volume connected to this port; and a virtual logical volume-setting controller for controlling the setting of a virtual logical volume. The virtual logical volume-setting controller is constituted such that the virtual logical volume cannot be set in a logical volume of the first storage controller.
