In a multi-path computer system, a host apparatus and devices are connected via a plurality of paths, recorded therein. From channel adapters of the devices, device information of said devices, area information corresponding to a plurality of accessible areas, channel-adapter number information in said devices, and/or component exchange-unit information in said device are obtained. Properlity of the plurality of paths is determined from access path information and identification information comprising the device information and area information. Identification information is informed, concerning an error path, comprising the device information and channel-adapter number information, to the other multi-path control parts of the own apparatus or the multi-path control parts of the other apparatuses, when detecting the error path. Operation of a path employing a channel adapter is caused to stop, and, also, identification information is informed of, concerning said channel adapter, comprising the device information and component exchange-unit information, to the other multi-path control parts of the own apparatus and/or the multi-path control parts of the other apparatuses, when a request of exchanging said channel adapter is given.
