    摘要: A plurality of key information items with a fixed constitution are stored in a shared memory of a first storage control system. Each key information item corresponds with each of the types of a second storage control system and includes, in a predetermined location in the key information, an information element that indicates the location of a particular information item among the plurality of information items in the control system information. A microprocessor in a Fibre Channel Adapter of the first storage control system determines whether to form a logical path with the second storage control system on the basis of the key information and the control system information that is received from the second storage control system.

    摘要: 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.
