Abstract
A system and method related to maintaining consistency of replicated data in a data storage environment. The system handles Input/Output (IO)-Requests in a data storage environment having a server and production data stored on a data storage volume on a data storage system. A copy of the production data is stored on another data storage volume of a second data storage system, wherein IO-Requests to update production data are handled so that the data copy is consistent with the production data after processing the IO-Request.
