    摘要： Provided are a computer program product, system, and method for concurrently processing parts of cells of a data structure with multiple processes. Information is provided to indicate a partitioning of the cells of the data structure into a plurality of parts, and having a cursor pointing to a cell in the part. Processes concurrently process different parts of the data structure by performing: determining from the cursor for the part one of the cells in the part to process; processing the cells from the cursor to determine whether to process the unit of work corresponding to the cell; and setting the cursor to identify one of the cells from which processing is to continue in a subsequent iteration in response to processing the units of work for a plurality of the processed cells.

    摘要： Methods, systems, and computer storage mediums including a computer program product method for formatting storage volumes are provided. One method includes creating a storage volume including a global counter and partitioned into multiple storage segments including a segment counter and partitioned into multiple stripes, wherein the global counter and each segment counter match at an initial time. The method further includes releasing the storage segments prior to completely reformatting the storage volume and subsequently incrementing the global counter such that the global counter and each segment counter no longer match at a subsequent time. The method further includes enabling a user to write data to the storage segments prior to completely reformatting the storage volume in response to incrementing the global counter. One system includes a processor for performing the above method and one computer storage medium includes a computer program product configured to perform the above method.

    摘要： In one aspect of write sort management in accordance with the present disclosure, a sort/no-sort determination is made prior to issuing to a write command to a target storage controller. The write command identifies a write data unit such track write data, for example, of a first write list of write data units to be written to storage locations of storage. The write command further identifies the storage location at which the write data unit of the first write list is to be stored. In one embodiment, the sort/no-sort determination determines whether an insertion point for an entry in a target write list is to be determined as a function of a write list search such as a logarithmic time search for a write list sort. As a result, the write list search for a write list sort, may be selectively either performed or bypassed for insertion of the target write list entry as a function of the sort/no-sort determination Other aspects and advantages are provided, depending upon the particular application.

    摘要： Provided are a computer program product, system, and method for establishing reverse paths between servers in a copy environment. A path establish request operation is initiated to establish paths between a first system and a second system for a copy relationship to copy data from a first storage to a second storage managed by the second system. In response to the path establish request, a pair of ports is established at the first system and the second system to use for a first path from the first system to the second system. The first system sends a reverse path establish request to establish a second path from the second system to the first system, wherein the second system sends messages to the first system on the second path for the copy relationship.

    摘要： Provided are computer program product, system, and method for using inactive copy relationships to resynchronize data among n storages referenced as storages 1 through n, wherein n is greater than or equal to three. n−1 active copy relationships are established. Each active copy relationship copies data from one of the storages 1 through n−1 as a source storage to one other of the storages 2 through n as a target storage respectively. At least one inactive copy relationship is established to copy data from one of the storages 1 through n−1 as the source storage to one other of the storages 2 through n as a target storage, such that the source and target storages in the inactive copy relationship are not both also in a same of at least one of the active copy relationships.
