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： 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.

摘要： In one embodiment of the present description, a copy relationship is established between a storage location at a first site and a storage location at a second site in a data storage system, wherein a dynamically assignable bitmap preset to one of a plurality of different predetermined bit patterns is selected as a function of both the availability of the selected bitmap and the type of predetermined bit pattern identified for the selected bitmap. The selected bitmap may be assigned as an out-of-sync bitmap wherein updates to the storage location at one site, which are to be copied to the storage location at the other site, are indicated in the selected bitmap, and data writes being written to the storage location at the one site, are copied to the storage location at the other site, using the selected bitmap as an out-of-sync bitmap. Other aspects are described.

摘要： Provided are a computer program product, system, and method for establishing a point-in-time copy relationship between source logical addresses and target logical addresses. A point-in-time (PiT) copy establish command specifies a source set comprising a subset of source logical addresses in at least one storage and a target set comprising a subset of target logical addresses in the at least one storage. The source set of source logical addresses are copied to the target set of target logical addresses. The source logical addresses map to source tracks and wherein the target logical addresses map to target tracks. Copy information is generated indicating whether the source logical addresses in the source set have been copied to the target set. Complete is returned to the PiT copy establish command after generating the copy information and before copying all the source logical addresses to the target logical addresses.

摘要： Provided are a computer program product, system, and method for managing updates and copying data in a point-in-time copy relationship expressed as source logical addresses and target logical addresses. A copy relationship indicates a source set of a subset of source logical addresses to copy to a target set comprising a subset of target logical addresses. An update is received to a source logical address that has not been copied. Determinations are made of the target logical address corresponding to the source logical address to be updated according to the copy relationship, a target group of target logical addresses in the target set that include the determined target logical address, and the source logical addresses in the source set that correspond to the target logical addresses in the target group. The determined source logical addresses are copied to the target logical addresses in the determined target group.

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： A method and/or system of managing metadata are disclosed that include connecting a source data storage system (DSS) that stores both data and metadata to a metadata management platform (MMP); scanning metadata records onto the MMP from the DSS; storing metadata attributes for at least one of the group consisting of directories and buckets on the DSS in a look-up table on the MMP; and adding updated metadata attributes to the look-up table on the MMP for each subsequent scan of the DSS.

摘要： Provided are a computer program product, system, and method for processing a copy command indicating a source set comprising a subset of source logical addresses to copy to an indicated target set comprising a subset of target logical addresses. Complete is expected to be returned to the copy command in response to completing the copying of the source set to the target set. A point-in-time (PiT) copy establish command is generated in response to receiving the copy command, indicating the source and target sets in the copy command, The generated PiT copy command is executed to generate copy information indicating the source and target sets of source logical addresses and whether they have been copied to the target set. Complete is returned to the copy command after generating the copy information and before copying all the source logical addresses to the target logical addresses.
