  • Patent number: 11144409
    Abstract: A method, system, and program product are provided for processing a host write operation during a recovery operation of a point-in-time copy restore. Provided are blocking the host write operation to the source volume based on whether a track on the source volume is copied to the target volume. A host and the point-in-time copy restore synchronize simultaneous access to the track using a track lock on track access, causing a requestor without the track lock to be queued until the track lock is available.

  • Patent number: 11132271
    Abstract: Provided are techniques for determining which target is most ahead in a multi-target mirroring environment between data from a consistent synchronous mirror copy operation and data from a consistent asynchronous mirror copy operation. It is determined that data is to be retrieved from one of a sync secondary storage of a sync secondary storage controller and an async secondary storage of an async secondary storage controller. Then, it is determined which one of data of a consistent synchronous mirror copy operation on the sync secondary storage and data of a consistent asynchronous mirror copy operation on the async secondary storage is a most current copy of the data. The most current copy of the data is retrieved and used for further processing.

  • Patent number: 11099751
    Abstract: Provided are a computer program product, system, and method for determining tracks to release in a source volume being copied to a target volume. A consistency group is formed of tracks in the source volume to copy to the target volume. A volume table providing information on the tracks allocated to the source volume is copied to a volume table copy in a memory providing a state of the tracks in the source volume as of a consistency group time. A determination is made of tracks in the source volume to release for tracks that are indicated in the volume table copy as available to release excluding tracks in the source volume that are written after the consistency group time. Space allocated to the determined tracks is released.

  • Patent number: 11100132
    Abstract: A method for more intelligently managing storage space in journal volumes is disclosed herein. In one embodiment, such a method includes maintaining, on a primary storage system, a change recording data structure that documents updated storage elements of a primary volume on the primary storage system. The method further determines in which extents of the primary volume the updated storage elements reside. These extents are recorded in an extent-based data structure. The method transmits the extent-based data structure from the primary storage system to a secondary storage system that is in an asynchronous mirroring relationship with the primary storage system. The extent-based data structure is then read at the secondary storage system. The method frees, from a journal volume on the secondary storage system, extents that are not recorded in the extent-based data structure. A corresponding system and computer program product are also disclosed herein.

  • Patent number: 11093178
    Abstract: Provided are a computer program product, system, and method for using a space release data structure to indicate tracks to release for a space release command to release space of tracks in a consistency group being formed. A space release command is received to free a release space of tracks in a source storage or target storage while transferring changed data in a consistency group to a target storage. A space release data structure is created indicating for each track of the tracks in the release space whether to release or not release the track. The space release data structure is initialized to indicate that each of the tracks is to be released. The tracks in the space release data structure are indicated to be released after the consistency group has completed.

  • Patent number: 11079935
    Abstract: Provided are a computer program product, system, and method for processing a space release command when mirroring data at a source storage to a target storage. A space release command is received to free a release space in the source storage while transferring changed data in a consistency group. A determination is made as to whether a transfer time to transfer remaining consistency group data in the consistency group for the release space that has not been transferred exceeds a response time to process a space release command. The remaining consistency group data in the release space is transferred to the target storage in response to determining that the transfer time does not exceed the response time. The release space for the space release command is freed in response to transferring the consistency group data in the release space to the target storage.

  • Patent number: 10885061
    Abstract: In one embodiment, upon initiation of a consistency group, bandwidth reduction scanning logic determines whether a volume portion such as a track containing data which is to be mirrored from a primary volume to a secondary volume to form a consistency group, is allocated to the primary volume. If not, the bandwidth reduction scanning logic causes the data of the associated volume portion to not be mirrored from the primary volume to the secondary volume. As a result, the volume portion determined to not be allocated to the primary volume is bypassed by the mirroring operation, thereby reducing bandwidth usage by the mirroring and accelerating the formation of a consistency group. Other features and aspects may be realized, depending upon the particular application.

  • Publication number: 20200409556
    Abstract: From a master node within a chain of nodes, a command is sent to form a consistency group. The command causes the chain of nodes to set, at the master node, a first change recording bitmap (CRB) containing a first set of host writes from a host system to an out of synch (OOS) bitmap. A consistent point of data is created across the chain using the OOS bitmap of the master node. At subsequent non-master nodes, the consistent point of data embodied in the OOS bitmap is drained to form the consistency group. During the draining, a second set of host writes is recorded to a second CRB at the master node. In response to a determining the consistency group has been formed, a second command is sent down the chain to reform the consistency group, wherein the second CRB is takes the place of the first CRB.

  • Patent number: 10824364
    Abstract: 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.

  • Patent number: 10776258
    Abstract: A method is disclosed for avoiding out-of-space conditions in an asynchronous data replication environment. In one embodiment, such a method creates a consistency group on a primary storage system of an asynchronous data replication environment. The method determines a number of additional extents that will be needed on a secondary storage system to accommodate the consistency group. The number of additional extents is compared to a number of free extents on the secondary storage system. In the event the number of additional extents does not exceed the number of free extents, the method transfers the data from the primary storage system to the secondary storage system. In the event the number of additional extents exceeds the number of free extents, the method automatically takes actions on the secondary storage system to provide the number of additional extents. A corresponding system and computer program product are also disclosed.

  • Patent number: 10733060
    Abstract: One general aspect of asynchronous local and remote generation of consistent point-in-time snap copies in consistency groups in accordance with the present description, is directed to receiving a local-remote pair point-in-time snap copy establish command to establish a local point-in-time snap copy in a local data storage system, and a remote point-in-time snap copy in a remote data storage system. In one aspect, establishment of the remote point-in-time snap copy relationship may be delayed as a function of the state of a consistency group formation process upon receipt of the local-remote pair point-in-time snap copy establish command. As a result, consistency of the local-remote pair of point-in-time snap copies may be realized, notwithstanding an asynchronous relationship between the local and remote storage systems. Other features and aspects may be realized, depending upon the particular application.
