摘要： An apparatus, system, and method are provided for controlling link status changes across multiple independent control modules. The apparatus includes a copy services module configured to control multiple link adapters, each configured to establish multiple communication links between a source and a target storage device. The adapter transmits a link status change notification to the copy services module and starts a timer upon transmitting the link status change notification. The copy services module simultaneously processes link status change notifications from a plurality of communication links. The system includes a communications network and a plurality of storage devices having the above described apparatus. The method includes controlling a plurality of link adapters configured to establish multiple communication links between storage devices, transmitting a link status change notification, starting a timer upon transmitting the link status change notification, and simultaneously processing link status change notifications from a plurality of communication links.

摘要： Methods, system and computer program product are provided to improve the efficiency of data transfers in a PPRC environment. A block of data to be transferred is divided into tracks. Each track is allocated to a data mover task control block (TCB) with a master TCB being assigned to supervise the data mover TCBs. The tracks are then transferred from the primary storage controller to the secondary controller in a piped fashion over a link coupling the primary and secondary storage controllers. However, the usage of resources is monitored by a resource management algorithm and, if too many TCBs are being used for a transfer or if the supply of data mover TCBs is exhausted, the transfer is automatically switched to a serial, non-piped transfer with the master TCB serving as the data mover TCB for the remaining tracks. In addition, the various links coupling the primary and secondary storage controllers is monitored to determine which link will provide the fastest transfer. If, during a transfer of tracks over one link, a faster link is identified, the transfer may be switched to the second, faster link.

摘要： A method to provide information from a first information storage and retrieval system to a second information storage and retrieval system. Applicants' method provides a first information storage and retrieval system, where that first information storage and retrieval system comprises (N) PPRC adapters and information, and provides a second information storage and retrieval system. The method generates and saves an Established Path Bitmap which recites each of the (N) PPRC adapters, and generates an Available Path Bitmap. If a PPRC adapter is in communication with the secondary information storage and retrieval system, then the method adds that adapter to the Available Path Bitmap. The Established Path Bitmap and the Available Path Bitmap are used for subsequent PPRC operations.

摘要： Disclosed is a method, system, and program for reducing an mount of data transferred. Indicators of sub-blocks modified for a block of data since the block of data was last sent to remote storage are maintained until the block of data is demoted. The maintained indicators are used to identify sub-blocks on the block of data for transfer to the remote storage.Disclosed is a method, system, and program for managing metadata in cache. A first policy is used to determine when to remove data from a primary cache, and a second policy is used to determine when to remove data from a metadata cache.

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 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.
摘要翻译：提供了一种同步数据存储系统的方法。该方法包括：指定第一数据存储系统和第二数据存储系统之间的关系，使得存储在第一数据存储系统中的数据被复制到第二数据存储系统，以响应于确定存储在第一数据中的数据存储系统已经修改; 接收修改存储在第一数据存储系统中的第一存储卷的第一数据块中的数据的第一请求，其中根据第一请求修改数据块; 当存储在第一数据块中的修改数据未被复制到第二数据存储系统时，确定第一数据块尚未成功同步; 以及执行重试所述第一数据块的同步的处理，直到所述第一数据块的同步成功，而不执行所述处理时暂停所述关系。
