摘要： A first data structure stores indications of storage locations that need to be copied for forming a consistency group. A second data structure stores indications of new host writes, subsequent to starting a point in time copy operation to form the consistency group. Locations of the first data structure and the second data structure are exchanged, subsequent to the consistency group being formed successfully.

摘要： A first data structure stores indications of storage locations that need to be copied for forming a consistency group. A second data structure stores indications of new host writes subsequent to starting a point in time copy operation to form the consistency group. Read access is secured to a metadata storage area and a determination is made as to whether the second data structure indicates that there are any new host writes. In response to determining that the second data structure indicates that there are new host writes, write access is secured to the metadata storage area, the first data structure is updated with contents of the second data structure to determine which additional storage locations need to be copied for formation of a next consistency group, and the second data structure is updated to indicate that that the second data structure is in an initialized state.

摘要： A storage controller receives a write command with respect to a track, from a host. A first process determines that the track is a source track and also determines that at least one corresponding target track is in an incremental copy relation to the source track. A second process is generated to modify a target change recording structure, where the second process executes in parallel with the first process.

摘要： Provided are a computer program product, system, and method for assigning levels of pools of resources in an operating system to a super process having sub-processes. A plurality of first level pools of resources are reserved in the operating system for first level processes to perform a first level operation and invoke at least one second level process to perform a second level operation. A plurality of second level pools of resources are reserved in the operating system for second level processes. One of the second level pools of resources assigned to one of the second level processes is released and available to assign to another second level process when the second level process completes the second level operation for which it was invoked.

摘要： In one embodiment, a copy relationship is established between a storage location at a first site and a storage location at a second site, in a manner which includes selectively either 1) synchronously writing a modified metadata track from a cache to data storage if the metadata track in cache is a mixture of ones and zeros, before staging from data storage into the cache, the next track of the sequence of tracks of metadata, or 2) instead of synchronously writing from cache the modified metadata track, entering a journal entry to protect the modified metadata track in cache if the metadata track in cache is one of all ones and all zeros, so that asynchronous writing of the modified metadata track from cache is substituted for synchronous writing from cache. Other aspects are described.

摘要： Provided are a computer program product, system, and method for releasing space allocated to a space efficient target storage in a copy relationship with a source storage. Source and target copy relationships indicate source data in the source storage to copy to target data in the target storage. The source copy relationship indicates source data that need to be copied to the target data before being updated, and the target copy relationship indicates target data tracks updated with data copied from corresponding source data. An operation is initiated that results in terminating the source and target copy relationships. Space allocated to the target data for the source and target copy relationships is released in response to determining that the target storage comprises the space efficient storage. The source and target copy relationships are removed.

摘要： In one embodiment, a local copy target is also a local primary of an incomplete consistency group of an ongoing asynchronous mirror relationship. Completion of the consistency group is facilitated notwithstanding that the local copy operation was initiated after the consistency group was initiated. In one aspect, asynchronous data mirroring logic, prior to the overwriting of existing data of the target, reads the existing data of the target for purposes of mirroring the read data to a remote secondary target of the consistency group. As a result, existing data of the local copy target which is also a local primary source of the consistency group, may be safely overwritten. Other features and aspects may be realized, depending upon the particular application.

摘要： Provided are a computer program product, system, and method for updating change information for current copy relationships when establishing a new copy relationship having overlapping data with the current copy relationships. A first copy relationship indicates changed first source data to copy to first target data. An establish request is processed to create a second copy relationship to copy second source data in to second target data. A second copy relationship is generated, in response to the establish request, indicating data in the second source data to copy to the second target data. A determination is made of overlapping data units in the first source data also in the second target data. Indication is made in the first copy relationship to copy the overlapping data units. The first source data indicated in the first copy relationship is copied to the first target data, including data for the overlapping data units.

摘要： In accordance with one embodiment, asynchronous local and remote generation of consistent first and second point-in-time snap copy volumes provides for generating in a primary system, a first point-in-time snap copy volume of a primary volume of the primary system, and generating in a secondary system, a second point-in-time snap copy volume utilizing a secondary volume in the secondary system. Synchronizing logic synchronizes the first and second point-in-time snap copy volumes to be consistent with each other as of a particular point-in-time notwithstanding an asynchronous mirror relationship between the primary volume of the primary system and the secondary volume of the secondary system. Other features and aspects may be realized, depending upon the particular application.

摘要： Provided are a computer program product, system, and method for using a cascade flag to process a copy relationship having a backward cascade copy relationship. Each of a plurality of copy relationships indicates to copy source data to target data and has a cascade flag. The cascade flag for a forward copy relationship of the copy relationships is set to a first value in response to determining that the source data for the forward copy relationship comprises target data for a backward copy relationship and that a background copy operation specified to copy source data to target data of the backward copy relationship has not completed. The cascade flag for the forward copy relationship is set to a second value in response to determining that the backward copy relationship does not have an uncompleted background copy operation.
