Storage control system

A storage control system, having a first storage controller and a second storage controller connected communicably with each other, and which carries out data processing according to a request from a host, wherein said first storage controller comprises:

• a storage device;
• a logical volume, which is accessed from said host;
• a data controller for controlling data processing between said storage device and said logical volume;
• a port capable of connecting to both said logical volume of said first storage controller and a logical volume of said second storage controller;
• and
• a discovery controller for executing a discovery operation, which extracts the information of logical volumes connected to the port, and displays extraction results on a screen, and
• the discovery controller is constituted so as to be able to process a predetermined logical volume from among the extracted logical volumes so as not to be displayed on a screen.

A storage control system, having a first storage controller and a second storage controller connected communicably with each other, and which carries out data processing according to a request from a host, wherein said first storage controller comprises:

• a storage device;
• a logical volume, which is accessed from said host;
• and
• a data controller for controlling data processing between said storage device and said logical volume, and
• said data controller is constituted such that copying between a logical volume of said first storage controller and an other logical volume having a logical configuration that differs from the logical configuration of this logical volume, is executed by way of a virtual logical volume built inside said first storage controller.

• and
• a virtual logical volume, which is set in association with logical volumes connected to this port, and said data controller is constituted so as to execute copying between a logical volume of said first storage controller connected to said port and an other logical volume inside said first storage controller, having a logical configuration that differs from the logical configuration of this logical volume, by way of said virtual logical volume, and the logical configuration of the virtual logical volume is set in accordance with the logical configuration of said other logical volume.
