摘要： With the migration of a logical volume between virtualization apparatuses, there has been a need to change the setting of a host computer in order to access a migration destination logical volume. In a control method for a computer system including a host computer, one or more storage systems, and plural virtualization apparatuses, a first virtualization apparatus includes a first memory and manages a first logical volume to which the host computer issues an access request, and a second virtualization apparatus includes a second memory and manages a second logical volume to which the host computer issues an access request, wherein the control method associates a first real storage area on the storage system, which has been associated with the first logical volume, with the second logical volume, and stores, in the second memory, first identification information that uniquely identifies the first logical volume within the computer system.

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： Disclosed is to reduce an amount of memory required for a difference bit map corresponding to a storage extent of large capacity. A difference bit map 27 is made into multi-tiers. A difference is expressed by a bit 321 of an entry 320 of a second tier. An entry 310 of a first tier is provided with a pointer 311 to the entry of the second tier and a representative bit 313, and the entry 320 of the second tier is made unnecessary when all values of the corresponding bits 321 are equal to a value of the representative bit 313.

摘要： Disclosed is a storage system having storage devices from which storage areas are specified. Virtualization apparatuses allocate the storage areas as virtual volumes and processes I/O requests with respect to the virtual volumes. A controller is operable to change the allocation of storage areas to the virtual volumes. The controller is configured to send a request to some of the virtualization apparatuses to temporarily suspend processing of their I/O. When a virtualization apparatus receives such a request, it completes its pending I/O and temporarily suspends subsequent I/O requests, and sends a completion report to the controller. The controller then changes the allocation of storage areas to the virtual volumes.

摘要： In a system comprising host computers and storage devices, storage regions maintained by storage devices are provided as virtualized volumes to the host computers by a virtualization function. In the case of allocating a vacant storage region from storage regions of a storage device to a virtualized volume, the virtualization function repeats to acquire and allocate a storage region from the vacant storage region until a remaining size within a required size becomes smaller than a maximum region size and, below the maximum region size, acquires and allocates a storage region, whose size is the smallest power of two not smaller than the remaining size, from the vacant storage region. If the vacant storage region includes a plurality of continuous vacant regions, the virtualization function selects the largest continuous vacant region for allocation.

摘要： In a system where a storage device is coupled to a computer, a storage area in the storage device is efficiently allocated to the computer. The system comprises a virtualization apparatus to be coupled to the computer and a plurality of storage devices to be coupled to the virtualization apparatus. The virtualization apparatus, responding to a request from the computer, issues a notice to the effect that a predetermined size of virtual volume has been allocated to the computer. The virtualization apparatus, upon receiving an access request from the computer to the virtual volume, allocates storage areas existing in a plurality of storage devices to the virtual volume, converts the access request received from the computer to an access request addressed to a storage device having the storage devices allocated to the virtual volume, and transmits the converted access request to the storage device.

摘要： For betterment, by putting a virtual storage device into a suspend mode, physical resources are turned OFF on a virtual storage device basis. Moreover, control information and volume data of the virtual storage device are stored in any external volume, for example, and the resources that have been used by the virtual storage device are deallocated. At the time of resumption of operation, using any resources not in use, the virtual storage device is restored based on the control information in storage. When a change is made to a WWN on the side of a host, the storage device receives a WWN change notification from a management server, and makes settings again to a WWN table, thereby making it accessible from the host.

摘要： This storage system has an allocation unit for allocating a storage extent in prescribed units to the dynamic logical volume upon storing the data sent from the host computer in the dynamic logical volume; a management unit for managing the storage extent recognized as being currently used by the file system among the storage extents allocated to the dynamic logical volume by the allocation unit; and a release unit for releasing the storage extent that is not being managed by the management unit from the dynamic logical volume.
