Abstract
A system, method, and program product are disclosed for asynchronous remote copy. One method includes transmitting a write request to a remote primary storage cluster for an asynchronous remote copy operation. The method also includes creating an entry in a write record stored in the local memory, the entry comprising a data consistency value, and removing the entry from the write record in response to receiving an acknowledgement from a remote secondary storage cluster that the asynchronous remote copy operation is completed.
