Abstract: A computer-implemented method, according to one approach, includes: receiving a first request to perform a write operation from a host, and performing the write operation. Metadata corresponding to the first request is sent to the secondary data storage device, and metadata corresponding to a second request to perform the write operation is received from the secondary data storage device, where the second request was received at the secondary data storage device from the host. The metadata corresponding to the first and second requests is used to determine whether the write operation has been mirrored across the primary and secondary data storage devices. In response to determining that the write operation has been mirrored across the primary and secondary data storage devices, a response is sent to the secondary data storage device which indicates that the write operation has been reconciled across the primary and secondary data storage devices.
