<p>[Problems] According to an aspect of the embodiments of the invention, it is an object to provide an information processing apparatus capable of exchanging the processors without stopping data transfer between the processors and an external apparatus. [Means for solving the Problems] According to an aspect of the embodiments of the invention, there is provided a method of switching internal settings in an information processing apparatus including a plurality of processors, a crossbar switch connected to the plurality of processors and having a first routing table and a second routing table used for routing between the plurality of processors and an external apparatus, and a management unit managing the plurality of processors. The method includes performing data communication with the external apparatus using the first routing table, when a configuration of the information processing apparatus is changed, updating configuration information in the second routing table, and instructing any one of the plurality of processors to switch the updated second routing table and the first routing table, and switching, by the processor instructed by the management unit, a routing table to be used for data communication from the first routing table to the updated second routing table.</p> |
