Patent ID: 7415593

Claim:
A storage control system having a first storage controller and a second storage controller connected communicably with each other which carries out data processing in accordance with a request from a host, wherein said first storage controller comprises: a plurality of storage devices, a plurality of first logical volumes to be configured from said plurality of storage devices and accessed from said host, a data controller configured to control data processing between said host and said plurality of first logical volumes, a port capable of connecting a first logical volume of said plurality of first logical volumes of said first storage controller and a second logical volume of a plurality of second logical volumes of said second storage controller, a channel interface unit configured to provide said first logical volume as a virtual logical volume to said host and manage a request from said host to said second logical volume of said second storage controller via said virtual logical volume, a memory including mapping information between said first logical volume and said second logical volume, and a management client unit configured to execute processing for setting said virtual logical volume, wherein when said management client unit sets said virtual logical volume, said channel interface unit acquires information of both said plurality of first logical volumes of said first storage controller and said plurality of second logical volumes of said second storage controller by referring to said memory and sends said information to said management client unit, said management client unit executes filtering processing for specifying said first logical volume from said plurality of first logical volumes based on said information, and displays said plurality of first logical volumes without said first logical volume on a screen of said first storage controller, and wherein said management client unit is configured so as to execute discovery processing for extracting logical volumes capable of being connected to said port as candidates for said virtual logical volume, and filtering processing for removing a logical volume of said first storage controller from this group of candidates.
