Abstract
According to an aspect of the invention, a computer comprises a memory; and a processor operable to manage a plurality of path groups, each of which includes a plurality of logical paths associated with a host computer, wherein each logical path of the plurality of logical paths connects the host computer to a logical volume of one or more logical volumes in one or more storage systems. The processor is operable to manage a priority of each path group of the plurality of path groups, and to use a logical path of a first path group instead of a logical path of a second path group for I/O (input/output) usage between the host computer and the one or more storage systems, representing a migration of I/O usage from the second path group to the first path group, based on at least the priorities of the first and second path groups.
