摘要： A computer system includes one or a plurality of host computers, a storage system including a disk device having a data volume for reading and writing data by the host computer, and a management computer for connecting the host computer and the storage system. The storage system obtains a snapshot of the data volume at a specific time point, holds the written journal after the specific time point, recovers the snapshot with the snapshot obtained at the time point near a recovery point, as the base, in the recovery, by applying the journal to the snapshot, specifies the journal depending on the snapshot or journal as a releasing target by using an order relationship used for determining the order between the snapshot, serving as the base, in the recovery, and the journal applied to the snapshot upon releasing the snapshot or journal, and releases the specified depending journal together with the snapshot or journal as a releasing target.

摘要： The computer system comprises a first and second computer, at least one first storage system connected to the first computer, and a plurality of second storage systems connected to the second computer as well as being connected to the at least one first storage system. The first computer issues to the first storage system a normal write request and control-use write request stamped with issue time. A control-use write request is issued at periodic intervals. The first storage system receives a write request and transmits the write request as update-data to second storage system in such a way that the issue order is ascertainable. The second storage system receives the update-data and, responsive to a reflect instruction from the second computer, reflects the update-data in storage areas. The second computer acquires the issued times stamped on update-data received by the second storage systems, establishes a standard time on the basis of issue times, and instructs the plurality of second storage systems to reflect the update-data whose issue time is at or prior to the standard time in storage areas.

摘要： Transfer of data and replication of data among several storage devices are executed without imposing a load on the computer connected to the storage system. For example, a first host computer monitors usage rates of transfer groups TG11, TG12 and physical path usage rate on a storage device interconnect physical path 50, and when either a usage rate or physical path usage rate goes above a predetermined value, issues to the first storage device 20 an instruction to allocate a reserved volume Ri 1, R12. The first host adaptor 21 receiving the reserved volume Rh, R12 allocation request allocates reserved volume Ru to transfer group TGI, whereby a virtual transfer volume is formed by transfer volume Til and the reserved volume Ru allocated thereto. As a result, capacity of the virtual transfer volume is increased by the equivalent of the reserved volume Ru capacity, so that additional transfer frames may be stored.

摘要： A hose clip for clamping a hose includes a clamping ring formed by annularly bending a strip of spring plate and deformed between a reduced-diameter state and a spread-diameter state. An arcuate portion is formed in either one of the ends of the clamping ring. A first knob is formed by bending the arcuate portion radially outward with respect to the clamping ring. A second knob is formed by bending the other free end of the clamping ring radially outward with respect to the clamping ring as so to pass through the arcuate portion. An engaged piece is formed on the one end of the clamping ring so as to project axially with respect to the clamping ring within a width of the spring plate. An engaging edge is formed on the other end of the clamping ring so as to move over the engaged piece and engage it when the first and second knobs are slid to come close to each other, thereby holding the clamping ring in the spread-diameter state with the knobs being substantially superposed. Also, a guide face is formed on a portion of the engaged piece with which the engaging edge engages. The guide face axially displaces the engaged piece and the engaging edge when the knobs come close to each other so that the engaged piece abuts the engaging edge.

摘要： This storage system modifies the migration plan in accordance with the state of the migration destination when a plurality of volumes are migrated all at once. Migration-source volumes are migrated collectively to volumes inside the migration-destination storage apparatus. The user can make settings related to migration-source volumes and migration-destination volumes in a migration plan, and can establish a mid-process control plan for modifying the migration plan in the middle of processing. If a failure occurs in the migration-destination storage apparatus subsequent to the commencement of data migration processing, a processing method controller either cancels or temporarily halts the data migration processing, or changes the migration destination, on the basis of the mid-process control plan. When changing the migration destination, a previously selected alternate storage apparatus is selected as the new migration-destination storage apparatus. When a failure occurs in the alternate storage apparatus, yet another alternate storage apparatus is selected.
