摘要： Disclosed is a technique for maintaining consistency of data. One or more blocks of data identified by a first structure are copied to form a consistent set of data. While not acknowledging completion of write requests to any blocks of data, a second structure is created, wherein the second structure indicates which blocks of data are modified while the consistent set of data is being formed. Also disclosed is a technique for asynchronous copy. Indicators are updated in a first structure for one or more blocks of data, wherein each indicator in the first structure indicates whether a corresponding block of data was modified since the block of data was last sent to remote storage. While copying the blocks of data identified by the indicators in the first structure as having been modified since the blocks of data were last sent to remote storage, indicators in a second structure are updated for the one or more blocks of data, wherein each indicator in the second structure indicates whether a corresponding block of data was modified while a consistent set of data is being formed.
摘要翻译：公开了一种保持数据一致性的技术。由第一结构标识的一个或多个数据块被复制以形成一致的数据集。在不向任何数据块确认写请求的完成的情况下，创建第二结构，其中第二结构指示在形成一致的数据集时修改数据块。还公开了用于异步复制的技术。指示符以用于一个或多个数据块的第一结构进行更新，其中第一结构中的每个指示符指示是否修改了相应的数据块，因为数据块最后发送到远程存储。由于数据块最后发送到远程存储，将第一结构中由指示符标识的数据块复制为已被修改，因此对于一个或多个数据块更新了第二结构中的指示符，其中每个指示符第二结构指示在形成一致的一组数据时是否修改相应的数据块。

摘要： Provided are a method, system, and program for forming a consistency group of data. Information is provided on a consistency group relationship indicating a plurality of slave controllers and, for each indicated slave controller, a slave storage unit managed by the slave controller. A command is transmitted to each slave controller in the consistency group relationship to cause each slave controller to transmit data in the slave storage unit to a remote storage in a manner that forms the consistency group. A determination is made as to whether all the slave controllers successfully transmitted the data in the slave storage units that is part of the consistency group to the remote storage.

摘要： A method for synchronizing data storage systems is provided. The method comprises designating a relationship between a first data storage system and a second data storage system, such that data stored in the first data storage system is copied to the second data storage system, in response to determining that the data stored in the first data storage system has been modified; receiving a first request to modify data stored in a first data block of a first storage volume in the first data storage system, wherein the data block is modified according to the first request; determining that the first data block has not been successfully synchronized when the modified data stored in the first data block is not copied to the second data storage system; and executing a process to retry synchronization of the first data block until synchronization of the first data block is successful, without suspending the relationship while the process is executed.

摘要： A target data storage system comprises a peer-to-peer communication link interface for linking the target to a source data storage system, and data storage for storing point in time copy data received from the source via the peer-to-peer communication link interface. Information is established at the target relating logical identification of the point in time copy data to point in time copy data stored at the target and to point in time copy data stored at the source, such that the information references the data storage system having requested point in time copy data. A controller of the target accesses requested point in time copy data at the target if the table indicates that the requested point in time copy data is available at the target; else obtains the requested point in time copy data from the source via the peer-to-peer communication link interface.

摘要： A method to initialize information disposed in an information storage and retrieval system comprising a data cache and one or more information storage media comprising a plurality of addresses. The method receives an initialization command, where that initialization command comprises a range of addresses and, optionally, an initialization pattern, where the plurality of addresses includes the range of addresses. The method forms and saves state information, where that state information includes the initialization pattern, and generates and saves a plurality of indicators, where that plurality of indicators includes an indicator for each track comprising the range of addresses. The method sets each of those indicators to a first value thereby indicating special handling, and provides an ending status signal, such that the receiving step, forming step, generating step, setting step, and providing step are performed substantially synchronously.

摘要： A method to coordinate interconnected information storage and retrieval systems, where each of the information and storage systems is capable of communicating with one or more host computers. The method provides a plurality of controllers and one or more information storage and retrieval systems, where each of the plurality of controllers is disposed in one of the one or more information storage and retrieval systems. The method designates one of the plurality of controllers as a master controller and the remaining controllers as target controllers. The method then generates one or more master controller commands by the master controller, and provides those one or more master controller commands to each of said target controllers, where the one or more master controller commands cause said target controllers to adjust the flow of data into and out of the one or more information storage and retrieval systems.
