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： 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： 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： A method for initiating a data storage facility recovery process in a data processing system having a first peer data storage facility and a second peer data storage facility communicating with the first peer data storage facility by a communication link. The method of initiating a recovery process is invoked by one peer data storage facility upon another peer data storage facility operating under a peer to peer remote copy (PPRC) protocol. Data copied from a first peer data storage facility to a second peer data storage facility is monitored for errors. Upon detection of an error by one peer data storage facility, recovery and data collection operations are initiated on the other peer data storage facility. Preferably, the initiation of recovery and data collection operations occurs out of band, over a second communication link between the peer data storage facilities.

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： A method of transmitting information from a primary storage control unit to a secondary storage control unit in an asynchronous data copying system. The method includes building multiple descriptor blocks for transmission from the primary storage control unit, and encrypting multiple payloads according to one of n encryption methods. In addition, the n encryption methods are associated with the primary storage control unit and n decryption keys relating to the n encryption methods are associated with the secondary storage control unit. An index to the n encryption keys is associated with the multiple descriptor blocks. The method further includes encrypting each of the payloads according to one of the n encryption methods and indicating, in the index associated with a selected descriptor block, which decryption key relates to the encryption method used for any payload associated with a select descriptor block. Upon transmission of a descriptor block from the primary storage control unit to the secondary storage control unit, the index is read and an appropriate decryption key is applied according to a decryption method to decrypt any payload associated with the descriptor block.
