摘要： With the migration of a logical volume between virtualization apparatuses, there has been a need to change the setting of a host computer in order to access a migration destination logical volume. In a control method for a computer system including a host computer, one or more storage systems, and plural virtualization apparatuses, a first virtualization apparatus includes a first memory and manages a first logical volume to which the host computer issues an access request, and a second virtualization apparatus includes a second memory and manages a second logical volume to which the host computer issues an access request, wherein the control method associates a first real storage area on the storage system, which has been associated with the first logical volume, with the second logical volume, and stores, in the second memory, first identification information that uniquely identifies the first logical volume within the computer system.

摘要： The object of the invention is to improve data access performance in a computer system. At least one logical volume is provided in a storage device 13 connected to a host computer via a network 17, and two different paths, a first path and a second path, which are unique to that logical volume, are assigned to the logical volume. The storage device 12 comprises: means for performing data access with respect to the logical volume identified by the first path, if a data access request from the host computer 12 has been received via the first path; and means for carrying out, if a data access request has been received from the host computer 12 via the second path, a prescribed processing before the received data access, and then performing data access with respect to the logical volume identified by the second path.
