Abstract
A storage control system is provided where a first host system connected to a first storage controller can issue a control command to a second storage controller connected another host system. The first storage controller is connected to the second storage controller and the command is issued without providing the command to the other host system. The first storage controller has a virtual volume, a memory unit for storing information necessary for mapping the virtual volume to a logical device in the second storage controller, and attribute information for the logical device. The host system identifies the virtual volume as the logical device in the second storage controller and issues a control command to this logical device via the virtual volume.
