摘要： A storage apparatus is capable of relocating volumes accurately even when a plurality of storage apparatuses are connected. The storage apparatus comprises an external connection function for recognizing an external logical volume set on a physical storage device as a logical volume inside the storage apparatus, a storage control device with a volume relocation function for relocating the logical volumes based on set conditions, and a storage unit with a plurality of physical storage devices. When the host sends a read request to the logical volume set on the physical storage device of the storage unit, the volume relocation function generates internally the same read request to the external storage volume set on the physical storage device in the external storage apparatus and relocates volumes based on the monitor information obtained by monitoring responses to the read request.

摘要： The present invention is devised so that snapshot data preparation processing does not end abnormally as a result of the pool region becoming full with saved data from the primary logical volume during snapshot data preparation. When the CHA receives a snapshot data preparation request, the CHA checks whether or not update information is present in the logical volume that is the object of this data preparation. If such information is present (YES in S51), a check is made from the number of slots in the in the volume control information and the updating amount count value in the update information in order to ascertain whether or not the proportion of the updating amount relative to the number of slots is equal to or greater than the threshold value in the threshold value control information (S52). If this proportion is equal to or greater than the threshold value (YES in S52), the update information is initialized (S53), and physical snapshot control is started (S54). If such is not the case (NO in S52), the update information is initialized (S55), and logical snapshot control is started (S56).
摘要翻译：本发明被设计为使得快照数据准备处理在快照数据准备期间由于来自主逻辑卷的保存数据而使池区域变满而不会异常结束。当CHA收到快照数据准备请求时，CHA检查在该数据准备的对象的逻辑卷中是否存在更新信息。如果存在这样的信息（S51中为“是”），则从更新信息中的音量控制信息和更新量计数值中的时隙数进行检查，以确定更新量的比例相对于时隙数等于或大于阈值控制信息中的阈值（S52）。如果该比例等于或大于阈值（S52中为“是”），则更新信息被初始化（S53），开始物理快照控制（S54）。如果不是这种情况（S52中为“否”），则更新信息被初始化（S55），开始逻辑快照控制（S56）。

摘要： Two data centers located in the vicinity are connected using a synchronous transfer copy function, and one of the data centers is coupled with a third data center disposed at a remote location by an asynchronous remote copying function. The order whereat a storage sub-system located in the vicinity has received data from a host is consistently guaranteed, and the third data center holds the data. Further, each storage sub-system includes a function whereby, during normal operation, data can be exchanged and the data update state can be obtained by the storage sub-systems located in the two data centers that do not directly engage in data transmission.

摘要： In an information processing system including a central processor for generating commands to process storage data stored and for executing a sequence processing and a storage subsystem including a plurality of storage media for transferring data between the plural storage media according to commands from the central processor, a data recovery method recovers data to a predetermined state upon occurrence of a failure in a sequence of processing executed by the central processor. Before execution of a sequence of processing, the central processor issues to the storage subsystem a saving request to save in the plural storage media a copy of data stored in either one of the storage media used in the sequence of processing. In response to the saving request, the storage subsystem saves a copy of data of the storage media.

摘要： The present invention appropriately processes a write command issued during data migration processing, and completes the data migration processing promptly. A copy control part 7, in a case where write data targeted at a migration-source volume 3A has been received from a host 2 during data migration processing, selects and executes one of a synchronous copy process 6A and an asynchronous copy process 6B based on either any one or multiple pieces of prescribed information 7A through 7D. This enables write command processing according to a process mode complying a storage system condition.
