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.

Arrangements for transfer and replication of data. A host computer retains a transfer volume management information including HDD identifiers corresponding to a plurality of primary volumes and identifiers of at least one of transfer volumes, wherein, from a plurality of volumes in a first storage device, the host computer extracts a reserve volume as an additional transfer volume, if a capacity usage of the at least one of the transfer volumes reaches or goes above a predetermined level, wherein the host computer transmits an allocation request about the additional transfer volume, wherein, after receiving the allocation request, the first storage device implements the reserve volume as the additional transfer volume corresponding to the at least one of transfer volumes for transfer of write data to the second storage device.

There is disclosed a data storage system used in a computer environment where there are plural host computers and plural storage array controllers. When a remote copy is made while assuring the order of writing across plural storage array controllers, one of the host computers gains copy information about all the storage array controllers associated with the remote copy as a representative. The representative one of the storage array controllers collects and stores copy statuses which are individually managed by the storage array controllers for which a remote copy is made. The host computer gains the copy statuses from the representative controller using an instruction to gain the copy statuses.

A CPU 11 executes a management program B (Pb), from a management program A (Pa) receives authentication information, a request, and a program ID, and determines whether the authentication information is correct. If the authentication information is correct, the CPU 11 acquires the execution authority information of the authenticated user, compares the received information, and determines whether execution authority corresponding to the received program ID is defined. If the CPU 11 determines that execution authority corresponding to the received program ID is defined, it established the defined execution authority as the execution authority for the management program B (Pb).

Provided is a storage medium management system, in which when the same data as that stored in a first physical storage area is stored in a second physical storage area, a storage system connected to a host computer compares the number of remaining rewritable times for the first physical storage area and the number of remaining rewritable times for the second physical storage area with each other. When the number of remaining rewritable times for the first physical storage area is less than the number of remaining rewritable times for the second physical storage area, the storage system writes data written from the host computer to the second physical storage area and copies the data written in the second physical storage area to the first physical storage area.

Provided is a computer system including: a plurality of storage systems interconnected via a network, each storage system including a logical volume that stores data; and a management computer that is connected to the storage systems via the network and includes a port connected to the network and a processor connected to the port, wherein: a logical volume of a transfer source in a storage system of the data transfer source and a logical volume of a transfer destination in a storage system of the data transfer destination are decided; it is determined whether it is necessary or not to migrate a license of a program used for the logical volume of the transfer source from one of the plurality of storage systems to the storage system of the transfer destination; and when it is determined necessary to migrate the license, license information regarding the license to the storage system of the transfer destination is migrated. Accordingly, costs of purchasing licenses necessary during data migration or the like are reduced.

In a storage system in which a pair is configured by a remote copy, when a fault occurs in the pair, data to be lost is determined. Provided is a management computer connected to a storage system, in which the storage system includes: a primary logical volume in which data is stored and an secondary logical volume in which a replication of the data stored in the primary logical volume is stored; the primary logical volume and the secondary logical volume form a pair; the management computer comprises a data management module for managing data stored in the primary and secondary logical volumes; and the data management module obtains an event regarding the pair, determines whether the event is caused by a fault occurring in the pair, determines data made to be inconsistent by the fault in the case where the event is caused by the fault, and outputs information on the inconsistent data.
摘要:
A computer system includes a host computer; a storage system for obtaining a snapshot, at a specific point in time, of a data volume, storing data written to the data volume after the specific point in time as a journal, and applying the journal to the snapshot for data recovery; and a management computer. In the computer system, the management computer instructs the storage system to determine whether data at a recovery point after a recovery point of the latest snapshot can be recovered within a specific period of time and to apply, if it has been determined that the data cannot be recovered within the specific period of time, a journal to the latest snapshot to update the latest snapshot to a new snapshot in such a manner that the data can be recovered within the specific period of time
