Patent ID: 7206823

Claim:
An information setting method executed by a management computer in a computer system in which a first network connects between each of a plurality of computers and a router, a second network connects between the router and a storage device, a network type of the first network differs from that of the second network, and the management computer is connected to each of said computers, said router, and said storage device through a management network, a network identifier being given to each port of said computers and each port of said router, said first network being connected to said each port, a network identifier being also given to each port of said router and each port of said storage device, said second network being connected to each port of said router and each port of said storage device, said information setting method comprising: acquiring information about the identifiers of the ports, and about the port connection relationship, from said computers and said router; analyzing the acquired information, and thereby creating a sequence of identifiers that have been given to said ports along an information transmission path from each of said computer to said storage device through the networks; and if said sequence of identifiers is specific to each of said computers on said first network, and is shared among the plurality of computers on said second network, separating said computers from one another in accordance with an identifier of a port on the low-order side of said router, and then creating a logical identifier having an identifier format of said second network; giving said logical identifier to said storage device in order to separately control each of said computers; and providing said router with said each logical identifier in accordance with each port on the high-order side of said router.
