Abstract
Provided is a control method for a computer system including one or more host computers, one or more storage systems, and a management computer. The storage system includes a plurality of controllers connected to the host computers through a network, and one or more logical volumes for storing data used by the host computers. At least one of the logical volumes is assigned to at least one of the controllers. According to the control method, when performance information of a controller exceeds a predetermined threshold, the logical volume assigned to the controller is assigned to another controller other than the controller. Thus, access loads on a storage system used in a network environment are balanced.
