Abstract: In a case of exchanging a migration source storage controller and a migration destination storage controller sharing one storage medium during replacement of storage devices, when hardware configurations or data management forms of the storage controllers are different, data in the storage medium cannot be shared even when data management information can be copied. Accordingly, a storage system, having a storage control unit and a storage drive provided with a storage medium, includes data management information for accessing data in the storage drive. A first storage control unit copies data management information about the data in the storage drive to a second storage control unit. When a write request is received from a host after copying of the data management information begins, each of the first storage and second storage control units stores write data related to the write request in a separate storage area of the storage drive.

Abstract: A processing method includes: a step of setting a workpiece having a workpiece surface made of a material containing metal, on a precision processing machine; and a forming step of forming multiple grooves having a V-shaped cross-section, at intervals of a constant pitch in a predetermined area on the workpiece surface, using a tool provided in the precision processing machine to thereby form a V-groove pattern made up of the multiple grooves, in the predetermined area. In the forming step, each time one groove is formed, the relative position between the tool and the workpiece is moved in a direction intersecting the longitudinal direction of the groove and the angle of the groove face of the groove is gradually varied so that a uniform color can be visually recognized in every location in the predetermined area when the predetermined area is observed from a predetermined viewpoint.

Abstract: This invention provides a storage system enabling it to properly rebuild a storage device involved in failure. In the storage system, a controller repairs data for which an access request has been issued, returns a reply to the source of the access request, and stores the repaired data. As regards data for which access is not requested, the controller executes rebuilding of storage regions corresponding to rebuild management units in priority-based order and changes priority for executing the rebuilding, based on access frequencies for a first period and access frequencies for a second period that is shorter than the first period.

Abstract: A storage system monitors the first access frequency of occurrence which is the access frequency of occurrence from a host device during a first period, and the second access frequency of occurrence which is the access frequency of occurrence from a host device during a second period shorter than the first period. Along with performing data relocation among the tiers (levels) in the first period cycle based on the first access frequency of occurrence, the storage system performs a decision whether or not to perform a second relocation based on the first access frequency of occurrence and the second access frequency of occurrence, synchronously with access from a host device. Here the threshold value utilized in a decision on whether or not to perform the first relocation is different from the threshold value utilized in a decision on whether or not to perform the second relocation.
