Patent ID: 8387044

Claim:
A storage system comprising: an FC (Fiber Channel) switch communicable with a host computer and a storage apparatus; and a management server for managing information, the management server being communicable with the FC switch, the host computer being a virtual host computer for communicating with the FC switch via a virtual interface, wherein the management server comprises: a storage part for holding server virtual interface management information for storing physical interface identifiers which are identifiers of a plurality of physical interfaces of the host computer grouped according to grouping information for grouping the physical interfaces, a virtual interface identifier which is an identifier of the virtual interface, and information on the virtual host computer, which are associated with each other, host information for storing the virtual interface identifier and information on the host computer, which are associated with each other, and volume information for storing the virtual interface identifier and a volume of the storage apparatus, which are associated with each other; and a display processing part for displaying information on a plurality of the virtual host computers on a display part in a manner in which any part of the information on the virtual host computers is arbitrarily selectable via an input part, and, upon selection of any part of the information on the virtual host computers via the input part, obtaining a virtual interface identifier corresponding to the selected part of the information on the virtual host computers, based on the server virtual interface management information of the storage part, obtaining information on a host computer corresponding to the obtained virtual interface information, based on the host information of the storage part, and displaying the obtained information on the host computer, or obtaining a virtual interface identifier corresponding to the selected part of the information on the virtual host computers, based on the server virtual interface management information of the storage part, obtaining information on a volume corresponding to the obtained virtual interface identifier, based on the volume information of the storage part, and displaying the obtained information on the volume on the display part, wherein the FC switch comprises an identifier conversion part for storing, when the FC switch transmits or receives data between the originating host computer and the storage apparatus, an originating physical interface identifier included in the data and a virtual interface identifier in association with each other, and for converting the virtual interface identifier included in response data to the data into the originating physical interface identifier.
