Abstract

On the screen of a computer, a server, a storage device and an FC switch are virtually provided and these devices are connected by a physical path. When an instance is generated in the server and the instance is dragged/dropped into the storage device, both the command to establish a multipath and the command to acquire a data area corresponding to the instance in the storage device are automatically generated. These commands are transmitted to the respective devices of an actually configured storage system.
