摘要： Provided are a method, system, and program for accessing a resource. Requests are generated to access a resource in a first access mode and a second access mode. The requests are processed to access the resource in the second mode before processing at least one request to access the resource in the first access mode. The processing of the requests to access the resource in the first access mode is delayed for a time period after processing all the requests to access the resource in the second access mode in order to wait to receive a subsequent request to access the resource in the second access mode.

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.
摘要翻译：公开了用于减少传送的数据的安装的方法，系统和程序。由于数据块最后一次发送到远程存储，因此数据块块修改的子块的指示器将被维护，直到数据块被降级为止。维护指标用于识别数据块上的子块以传输到远程存储。

摘要： For 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.

摘要： Provided are a method, system, and article of manufacture for managing writes received to data units that are being transferred to a secondary storage as part of a mirror relationship. Synchronization information indicates data units to transfer from a primary storage to a secondary storage, wherein the synchronization information data is updated to indicate the transfer of one of the data units from the primary storage to the secondary storage. A storage controller receives a write request having an update to a target data unit comprising one of the data units indicated in the synchronization information that has not been transferred from the primary storage to the secondary storage. The write request is allowed to apply the update to the target data unit in response to transferring the data in the target data unit to a network adapter of the storage controller and before the data in the target data unit is transferred to the secondary storage.

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.
