COMPUTER SYSTEM HAVING A PLURALITY OF STORAGE NETWORKS AND METHOD FOR SETTING INFORMATION

In a computer system having two or more kinds of storage networks, effective information is set by use of network identifiers. An identifier acquisition unit, and a router information acquisition unit, of a management computer acquire a network identifier of a port, and information about the port connection relationship, from a computer and a protocol-conversion-type router. An identifier analyzing unit creates an identifier path from each computer to a storage device. A setting judgment unit judges whether this identifier path is independent of, or shared by, identifier paths of the other computers. According to the judgment, instead of using a network identifier of the computer, a setting execution unit uses, for information settings, an identifier of a port on the low-order side of the protocol-conversion-type router or a logical identifier that is generated.
