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： 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.

摘要： Provided are a method, system, and program for forming a consistency group of data. A command is received to form a consistency group with respect to data received at a first storage site that is mirrored to a second storage site. A first data structure is provided indicating updates to the first storage site not included in the consistency group that are received after the command and a second data structure is provided indicating updates to the first storage site in the consistency group to be formed. A command is transmitted to cause data copied to the second storage site that is part of the consistency group to be copied to a third storage site. Indication is received when the data in the second storage site that is part of the consistency group is copied to the third storage site.

摘要： Techniques are provided for performing a copy operation. An instant virtual copy operation is issued from a first portion of data to a primary mirroring portion of data, wherein the primary mirroring portion of data corresponds to a secondary mirroring portion of data, and wherein the primary mirroring portion of data and the secondary mirroring portion of data are in a mirroring relationship. The mirroring relationship is transitioned to a duplex pending state in response to determining that the mirroring relationship is in a full duplex state. When the mirroring relationship is in a duplex pending state, each block of data involved in the instant virtual copy operation is transferred from the primary mirroring portion of data to the secondary mirroring portion of data.

摘要： An apparatus, system, and method are disclosed for replicating point-in-time copies of local data to a remote site. The present invention mirrors point-in-time copy directives on the local data store to initiate a point-in-time copy operation on the remote copy of the local data, thereby efficiently providing remote access to a point-in-time copy of a dataset. Data integrity is ensured by committing local and remote point-in-time copy operations subsequent to successful initiation of both local and remote point-in-time copy operations. The present invention also, in one embodiment, rolls back a point-in-time copy operation in response to a failure to replicate the copy operation.

摘要： Resynchronization of data between a primary (production) data site and a secondary (recovery) site following a failure is enhanced when the size of a data track at the production site is different from the size of a data track at the recovery site. The recovery site reads an out-of-sync (OOS) bitmap created at the production site and expands or contracts the bitmap to accommodate the size difference. The resulting production site bitmap is merged with a OOS bitmap maintained at the recovery site to indicate those tracks which are to be transferred from the recovery site to the production site. Thus, only those tracks which are required to be transferred are transferred. Buffer space may be allocated in which to expand or contract the production site OOS bitmap. Buffer space may be conserved by sequentially reading portions of the production site OOS bitmap into a small buffer. In a first operation, half of the bitmap portion is discarded and the remaining half is expanded into the buffer and merged with a corresponding section of the recovery site OOS bitmap. In a second operation, the portion is re-read into the buffer and the other half discarded. The remaining half is then expanded into the buffer and merged with the corresponding section of the recovery site OOS bitmap. The process continues until the entire production site OOS bitmap has been merged with the recovery site OOS bitmap.
摘要翻译：当生产现场的数据轨道的大小与恢复站点上的数据轨道的大小不同时，会在故障后的主要（生产）数据站点和辅助（恢复）站点之间重新同步数据。恢复站点读取在生产站点创建的不同步（OOS）位图，并扩展或收缩位图以适应大小差异。生成的生产站点位图与恢复站点上维护的OOS位图合并，以指示要从恢复站点传输到生产站点的轨道。因此，仅传送需要传送的那些轨道。可以分配缓冲区空间来扩展或收缩生产站点OOS位图。可以通过将生产站点OOS位图的部分顺序读入小缓冲区来保存缓冲区空间。在第一个操作中，位图部分的一半被丢弃，剩下的一半被扩展到缓冲区，并与恢复站点OOS位图的相应部分合并。在第二操作中，该部分被重新读入缓冲器，另一半被丢弃。然后剩下的一半扩展到缓冲区并与恢复站点OOS位图的相应部分合并。该过程一直持续到整个生产站点OOS位图已经与恢复站点OOS位图合并。
