Abstract:
An information processing apparatus includes a plurality of devices, each including a memory that stores link-status information indicating whether or not an error occurs in a link connected to the each device. When a first device among the plurality of devices fails to receive within a predetermined time period a response for a request that has been transmitted by the first device, the first device obtains the link-status information from relevant devices each related to at least one of transfer of the request and transfer of the response, and identifies a link in which the error has occurred or a device that is connected to the link, based on the obtained link-status information.
