摘要： A primary storage controller is configured to communicate with a secondary storage controller via a system data mover. In response to receiving a command to perform a point in time copy of a source volume of the primary storage controller to a target volume of the primary storage controller, a determination is made as to whether the target volume of the primary storage controller is a source for an asynchronous data replication operation, initiated by the system data mover, between the primary storage controller and the secondary storage controller. In response to determining that the target volume of the primary storage controller is the source for the asynchronous data replication operation, initiated by the system data mover, the point in time copy of the source volume of the primary storage controller to the target volume of the primary storage controller is performed.

摘要： In one embodiment, a computer program product for handling a point-in-time copy (PITC) command includes a computer readable storage medium having computer readable program code embodied therewith. The computer readable program code is configured to: receive a PITC command at a local site, create a data representation that represents updates to make to the at least one target volume of the local target storage location, wherein the updates correspond to changes made to at least one source volume of the local source storage location since execution of an earlier PITC command, create a source data sidefile entry for the at least one source volume, create a target data sidefile entry for the at least one target volume, execute the PITC command at the local site, and create a PITC sidefile entry for the PITC command, the PITC sidefile entry including a timestamp that indicates when the PITC command was executed.

摘要： Methods, computing environments, and computer program products are provided for replicating data. Point-in-time copy parameters are generated at a primary host site. A side file entry having the point-in-time copy parameters and a track information field (TIF) associated with the point-in-time copy parameters is generated. The side file entry is transferred to a secondary host site. A point-in-time copy process is performed at the secondary host site based on the point-in-time copy parameters and the TIF.

摘要： A first command is sent from a primary host system to a primary storage controller device, specifying that a first primary volume is to be flash-copied to a second primary volume. Flash-copying provides for completion of copying the first primary volume to the second primary volume to be signaled prior to data on the first primary volume being physically copied to the second primary volume. A first state of the first primary volume and the second primary volume is verified by the primary storage controller device to determine whether the first state permits flash-copying of the first primary volume to the second primary volume. A first query is sent from the primary storage controller device to a secondary host system, requesting whether a first secondary volume can be flash-copied to a second secondary volume. The first and second secondary volumes asynchronously mirror the first and second primary volumes, respectively.

摘要： A method for managing storage functions in a data replication environment is disclosed. In one embodiment, such a method includes continually monitoring for changes to a storage configuration at a secondary site. Upon detecting changes to the storage configuration at the secondary site, the method transmits remote metadata describing the changes to the primary site and stores the remote metadata at the primary site. The method then initiates a storage management function at the primary site which is mirrored to the secondary site. In order to perform the storage management function, the method reads the remote metadata at the primary site to determine the storage configuration at the secondary site. The method then performs the storage management function at the primary site in a way that takes into account the storage configuration at the secondary site. A corresponding apparatus, system, and computer-readable medium are also disclosed and claimed herein.
