Computer systems forming the computer system group each have a plurality of servers, a plurality of I/O devices, a plurality of servers, and one or more I/O switches coupled to the plurality of I/O devices, and it is possible to change the combination of the servers and I/O devices in each of the computer systems. If a fault has occurred in one of the current servers, firstly, it is judged whether or not there exists a spare server capable of taking over processing in a computer system including the server which has generated the fault. If the judgment result is negative, then a server switching process is carried out by searching another computer system capable of constructing a particular combination corresponding to the combination of the faulty server and the I/O devices allocated thereto. |
