Abstract:
1. A computer readable recording medium having recorded thereon a computer program for a computer system in which a host computer and a storage system are connected via at least one intermediate device to enable communication, wherein said storage system includes a storage device capable of data storage, and said host computer recognizes a logical path from said host computer to said storage device, said computer program when executed causes said computer to perform the steps of: specifying a plurality of physical paths, which exists between said host computer and said storage system; specifying to which physical path of said specified plurality of physical paths said logical paths corresponds; and making said logical path correspond to said specified physical path, wherein each of said at least one intermediate device comprises a plurality of intermediate ports, which are ports to be connected to said host computer, said storage system or another intermediate device, wherein said host comprises a host port, which is a port to be connected to an intermediate device, and a storage resource capable of storing said logical path, wherein said storage system comprises a storage port, which is a port to be connected to an intermediate device, wherein said logical path is represented by a host/storage port identifier (ID) for specifying at least one from among said host port and said storage port, and a storage device ID for specifying said storage device, wherein said physical path is represented by a host port ID for specifying said host port, an intermediate port ID for specifying said intermediate port, and a storage port ID for specifying said storage port, and said computer program when executed further causes said computer system to perform the step of: specifying the physical path to which said logical path corresponds, by specifying, from among said plurality of physical paths, a physical path comprising either a storage port ID or a host port ID, which conforms to a host/storage port ID contained in said logical path.
