摘要： Composition of a consistency group is changed easily without releasing a volume pair of the consistency group concerning a remote copying system and a remote copying method using a sequence number. In order to change the composition of the consistency group, predetermined data sent from a data sending side after the relevant change is received. At that time, a reflection operation of the predetermined data on a logical storage area is started on a data receiving side after reflection of the predetermined data sent from the data sending side before the relevant change on the logical storage area is terminated.

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： In asynchronous remote copy, there is time difference between data update and remote copy in a primary storage system. The primary storage system loses data unreflected on a secondary storage system in disaster and cannot control the amount of data lost. The primary storage system obtains the data reflection state of remote copy between it and the secondary storage system to manage the amount of data update delay between the storage systems. When the amount of delay meets a configured start condition, a process of reducing the amount of delay is started. When the amount of delay meets a separately configured stop condition, the process of reducing the amount of delay is stopped. The configuration of whether the process of reducing the amount of delay is performed and the configuration of the conditions are performed from outside.

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 apparatus installed in a first site generates a snapshot of a copy source logical device in an intermediate logical device. Next, an external storage apparatus including a logical device corresponding to the intermediate logical device is disconnected from the first site and connected to the second site. A storage apparatus in the second site is made to recognize the logical device in the external storage device as a logical device of a remote copy target. Next, the storage apparatus instructs the second site about writing in the copy target logical device through a global network on the basis of the difference data managed with the bit map.

摘要： In the storage controller of the present invention, different difference bitmaps are used for predetermined sections respectively, whereby the difference between the primary volume and the base volume is managed for each section, and the data are protected efficiently. The difference between the primary volume and the base volume is managed by using the difference bitmaps that are different for the respective sections. The journal data after a lapse of the targeted protection period are written to the base volume and then discarded. At the time of recovery, the difference bitmaps are merged to create a new difference bitmap, and the difference is copied from the base volume to the primary volume. Thereafter, the journal data up to the designated restoration point are written to the primary volume.

摘要： Systems and methods described herein are directed to determining a partial migration plan to execute based on a policy. In situations where the performance of the virtual volumes is insufficient, the virtual volume should be migrated to a different storage pool or have high-performance media added to its current storage pool. A management program creates several migration plans for execution, which may include more than one partial migration plans. The plans may indicate the original storage subsystem, the target storage subsystem and a number of pages. The management program selects one of the plans, and proceeds to execute the selected plan.

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.
