摘要： An externally-connected volume of a main storage is correlated to an AOU volume inside of an external storage. The AOU volume is allocated with a not-yet-used page in a pool in accordance with data writing. When a command is issued to the externally-connected volume for formatting or others, a first controller in the main storage converts the command into a format command or an area deallocation command with respect to the AOU volume in the external storage. As such, the external AOU volume is subjected to a write process in its entirety, thereby being able to prevent any unnecessary page allocation. With such a configuration, the storage system of the present invention can use pages in the pool with good efficiency.

摘要： One code (a compressed redundant code) is created based on a plurality of first redundant codes, each created on the basis of a plurality of data units, and this compressed redundant code is written to a nonvolatile storage area. This compressed redundant code is used to restore either a data element constituting a multiple-failure data, or a first redundant code corresponding to the multiple-failure data, which is stored in an unreadable sub-storage area of a partially failed storage device, and to restore the data element constituting the multiple-failure data which is stored in a sub-storage area of a completely failed storage device, based on the restored either data element or first redundant code, and either another data element constituting the multiple-failure data or the first redundant code corresponding to the multiple-failure data.

摘要： A storage system is utilized to its fullest storage capacity by setting a write inhibitive attribute to a desired storage area of the storage system. The storage system has a logical volume in which data is stored and a control device which controls access to the data stored in the logical volume. A first area of a desired size is set in the logical volume, and an access control attribute is set to the first area. In response to a request made by a computer to perform access to the logical volume, the control device notifies the computer that the control device does not perform the access when an area designated by the access request contains at least a part of the first area and the access control attribute set to the first area inhibits the type of the access requested.

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 storage system for storage of data written from a computer, and when a write request of data to a first logical volume is received, the data on request is stored into the first logical volume. When a first-generation snapshot creation request is received, the data stored in the first logical volume at the time of receiving the first-generation snapshot creation request is written into a pool region as data corresponding to a first-generation snapshot, and when a second-generation snapshot creation request is received, any portion of the data updated after the first-generation snapshot creation request is received but before the second-generation snapshot creation request is issued is read from the first logical volume for writing into the pool region. Such a storage system favorably implements snapshot backup with no dependency with a positive volume in terms of performance and failure, and with high capacity efficiency.

摘要： The present invention provides a method for guaranteeing a data consistency among a plurality of storages and sites, when data transfer is performed by asynchronous remote copying from a site including a plurality of storages. When writing is made into a first storage system or a second storage system, the storage system that received the writing transfers the write data to the other storage system within the site by synchronous remote copying. At this timing the first storage system gives the write data information for order assurance. Furthermore, the first or the second storage system transfers the write data and thus given information for order assurance to the third or the fourth storage system by asynchronous remote copying. Furthermore, the third or the fourth storage system which has received the write data transfers to the other storage system within the same site the write data and information for order assurance by synchronous remote copy.

摘要： In a system comprising a first storage system providing plural first logical volumes including real logical volume and a virtual logical volume with a host, a second storage system having a second logical volume, and a management computer, when the first storage system receives an access request to the virtual logical volume, it accesses a second logical volume associated with the virtual logical volume. In this system, when the management computer receives a request to guard one of the plural first logical volumes, it checks whether a target first logical volume of the request is a real logical volume or a virtual logical volume, in case of the virtual logical volume, generates and provides a possible at least one option to guard the virtual logical volume by considering a program for volume guard, which each of the first storage system and the second storage system has.
