Abstract: A storage system creates an HA configuration in a virtual storage composed of resources of first and second storage subsystems. A user of the virtual storage selects a replication destination volume (second logical volume) of a first logical volume of the first storage subsystem that the user wishes to duplicate from the second storage. At this time, only a logical volume not recognized from a host is selectable as the second logical volume. When data duplication between the first logical volume and the second logical volume is started, the second storage subsystem sets an identification number of the second logical volume to be the same as the identification number of the first logical volume. Thereafter, at the point of time when duplication is completed, the second storage changes the setting of the second logical volume so that the second logical volume can be recognized from the host.

Abstract: A storage system has a management computer and a storage device, where the storage device is connected to an external storage device and includes a first processor, a storage medium on which a plurality of logical storage devices is based, and a plurality of ports. The management computer includes a memory and a second processor, the memory storing port information, path information between host and storage device indicating the association between a host computer and the plurality of logical storage devices and ports, and path information between storage devices indicating the association between the external storage device and the plurality of logical storage devices and ports. The second processor executes band accommodation processing on either a path between host and storage device or a path between storage devices on the basis of the port information, the path information between host and storage device, and the path information between storage devices.

Abstract: Technique for decision criterion for determining a transfer destination layer in rearrangement processing. A computer configures rearrangement reference information showing whether an access characteristic related to a task executed on a plurality of host computing devices is considered as a decision criterion for transfer destination determination in rearrangement processing of transferring data between actual storage areas of physical storage devices of different response performance. Storage subsystem refers to the rearrangement reference information and, based on an access characteristic of the plurality of computing devices with respect to the actual storage areas assigned to the plurality of computing devices, executes rearrangement processing of transferring data stored in the actual storage areas to different actual storage areas in the physical storage devices of different response performance.
