A method for displaying an access path between a virtual volume of a storage controller that has an external storage connecting function, and an external volume of an external storage system. By this method, port connection information about an access path defined between the virtual volume and the external volume is collected. A first network address for identifying an access port of the storage controller on the access path is collected. Also, a second network address for identifying an access port of the external storage system on the access path is collected. Moreover, identification information for identifying the external volume is collected. Finally, the network topology between the virtual volume and the external volume is displayed based on the port connection information, the first network address, the second network address, and the identification information.
