ABSTRACT:
Provided is a method of controlling a computer system that includes: a computer; a first storage device connected to the computer via a first path and a second path; and a second storage device externally-connected to the first storage system via a third path and connected to the computer via a fourth path, the first storage device providing a first storage area to the computer, the second storage device including a second storage area corresponding to the first storage area, the method including: judging whether or not a fault has occurred in at least one of the first to fourth paths; selecting, a path used for access to the first or second storage area; and transmitting the access request for the first or second storage area by using the selected path. Accordingly, in the computer system, an application can be prevented from being stopped despite a fault in a path.
