Abstract
When a failure is detected in a server currently being used, a management server changes the network topology for the server currently being used and another server which substitutes the server. Then, the management server instructs the network SW with the changed network topology so as to cause the network SW to set the network topology logically. In addition, the management server instructs a disk array unit to control accesses from the other server to the disk in accordance with the server where the failure is detected.
