    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: 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.
