Abstract:
1. A computer, comprising: a processor; and an interface coupled to a plurality of storage systems and a switch, wherein each of the plurality of storage systems includes a controller and at least one logical volume, wherein the switch couples to the plurality of storage systems and a host computer, and maps at least one of a plurality of logical volumes of the plurality of storage systems to at least one virtual volume to provide an access to the at least one virtual volume with the host computer, wherein the processor receives logical volume information from the plurality of storage systems via the interface, wherein the processor receives virtual volume information from the switch via the interface, wherein the logical volume information includes configuration information and identifying information of the plurality of logical volumes of the plurality of storage systems, wherein the virtual volume information indicates a mapping between the at least one virtual volume and the at least one logical volume mapped to the virtual volume by the switch, and wherein based on the logical volume information and the virtual volume information, the processor outputs information showing whether each of the plurality of logical volumes is mapped to the at least one virtual volume and relation information between the at least one virtual volume and the at least one of the plurality of logical volumes mapped to the at least one virtual volume.
