Abstract:
1. An apparatus for supporting a configuration of a storage system including an upper level device with at lease one port, an input/output device with at least one port and a path control device provided between the upper level device and the input/output device, comprising: a first information acquisition unit which acquires information about the upper level device, the input/output device and the path control device; a second information acquisition unit which acquires information about a physical connection among the upper level device, the input/output device and the path control device; an allocation unit which allocates temporary port information to respective ports provided in the upper level device and the input/output device; a path information generation unit which generates path information about a logical path to be established between the upper level device and the input/output device through the path control device based on the information acquired by said first and the second information acquisition units using the temporary port information; an inquiry unit which inquires port information of respective ports provided in an upper level device and an input/output device provided in an actually configured storage system; a replacement unit which replaces the temporary port information being used in the previously prepared path information with actual port information obtained by the inquiry; an instruction preparation unit which prepares instruction to control conditions of the upper level device, the input/output device and the path control device based on the path information modified by said replacement unit; and a transmission unit which transmits the instruction prepared by said instruction preparation unit to the upper level device, the input/output device and the path control device.
