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 method to maintain write operation atomicity where a write operation crosses a data storage medium track boundary. The method supplies a storage controller comprising a host adapter, a processor, and a NVS. The host adapter receives from a host computer a write request and data. The method determines if the write request will cross a data storage medium track boundary. If the write request will cross a data storage medium track boundary, the method indicates to the host adapter that the write request comprises a two-track transfer, and writes the data to the NVS as the data is received. If the host computer fails prior to providing all the data to the storage controller, the method discards the data written to the NVS to ensure write operation atomicity.

摘要： A mechanism is provided for managing operations in a data storage system. A first storage controller monitors operation state information associated with a plurality of operation states stored in a data structure. The first storage controller detects a change in the operation state information. The change in the operation state information is in response to a managing entity updating the operation state information to a first operation state in the plurality of operation states in the data structure. Responsive to detecting the change in the operation state information, the first storage controller identifies a reference to a first operation associated with the first operation state updated by the managing entity. The first operation is one operation in a plurality of operations. The first storage controller performs the first operation associated with the first operation state.

摘要： An apparatus, system, and method are disclosed for selecting a space efficient repository. A cache receives write data. A destage module destages the data sequentially to a coarse grained repository such as a stride level repository and destages a directory entry for the data to a coarse grained directory such as a stride level directory if the data satisfies a repository policy. In addition, the destage module destages the data to a fine grained repository such as a track level repository overwriting an existing data instance and destages the directory entry to a fine grained directory such as a track level directory if the data does not satisfy the repository policy.

摘要： An apparatus, system, and method are disclosed for activating a synchronous mirror as a primary storage volume. The apparatus system and method include directing a third storage volume to store updates sent to the third storage volume from a second storage volume onto a first storage volume in response to the first storage volume becoming operational after a failure, terminating sending updates from the second storage volume to the third storage volume in response to the first storage volume becoming substantially consistent with the third storage volume, and synchronously storing updates received by the second storage volume on the first storage volume and asynchronously storing updates received by the first storage volume on the third storage volume in response to terminating sending updates from the second storage volume to the third storage volume after the first and third storage volumes are substantially consistent.
