摘要： This storage apparatus includes a first logical volume migration unit for migrating the logical volume of a first storage area targeted for power source shutdown to a second storage area that is not targeted for power source shutdown based on an external command, and a second logical volume migration unit for migrating an expiration date-defined logical volume from the second storage area to a third storage area of a post-expiration migration destination when the expiration date of the expiration date-defined logical volume set with an expiration date for migrating the logical volume is reached. The first logical volume migration unit balances and migrates the expiration date-defined logical volume to the second storage area by referring to the expiration date of the expiration date-defined logical volume and taking into consideration the migration timing to the third storage area.

摘要： In a data processing system having a primary site and a secondary site, storage systems are connected to each other via a communication line, data update history is recorded in a storage device as a journal in the primary site, and the journal is transferred to the secondary site via the communication line. During such transfer, loads will not concentrate to a specific volume, by switching the volume that stores the journal in the primary site, while, by switching the transfer-destination volume of the journal in the secondary site.With such arrangement, in a data processing system, it is possible to ensure data consistency in a plurality of sites and prevent the system throughput capacity from being deteriorated without applying loads to a host and a network, and without causing load concentration on a specific storage device that is caused as a result of data update or recovery operations.
摘要翻译：在具有主站点和次站点的数据处理系统中，存储系统经由通信线路彼此连接，数据更新历史记录在作为主站点中的日志的存储设备中，并且将日志传送到辅助站点通过通信线路。在这种传输过程中，通过在主站点中切换存储日志的卷，而通过切换辅助站点中日志的传输目的地卷来，加载将不会集中在特定卷上。通过这种布置，在数据处理系统中，可以确保多个站点中的数据一致性，并且在不向主机和网络施加负载的情况下防止系统吞吐量容量恶化，并且不会对特定存储器造成负载集中由于数据更新或恢复操作而导致的设备。

摘要： The storage controller of the present invention can efficiently execute recovery by using the storage contents of the primary volume and of the base volume as much as possible. The difference between the primary volume and the base volume is managed by using difference bitmaps that differ in the sections. At the time of recovery, the differences that occur after the restoration point and before the restoration point are managed in the respective bitmaps. The base volume can be used in the area updated only after the restoration point, and the primary volume can be used in the area updated only before the restoration point. In the areas that are updated before and after the restoration point, the data of the base volume is copied to the primary volume, and thereafter the journal data obtained up to the restoration point are written to the primary volume.

摘要： A migration destination storage creates an expansion device for virtualizing a migration source logical unit. A host computer accesses an external volume by way of an access path of a migration destination logical unit, a migration destination storage, a migration source storage, and an external volume. After destaging all dirty data accumulated in the disk cache of the migration source storage to the external volume, an expansion device for virtualizing the external volume is mapped to the migration destination logical unit.

摘要： A consumption value of each storage medium and an upper limit related to writing are managed. Respective consumption value and the upper limit of each of two or more storage media out of a plurality of storage media constituting a storage media group are specified, and a remaining use period value is computed for each of the storage media using the upper limit and the consumption value. Based on each of the computed remaining use period values, data in at least one storage medium out of a plurality of storage media belonging to the selected storage area group is shifted to a storage medium which is different form the storage area group.

摘要： An access control attribute that can be established for an extent that is provided in a storage device may be any access control attribute signifying write permission, read permission, and write prohibition, but an access control attribute signifying read prohibition is not supported. In cases where a read request for read target data is received from a communication device that transmits the read request, the data processing system reads read target data from a read source extent without retrieving an access control attribute of the read source extent according to the read request from among a plurality of access control attributes.
