Abstract: A synchronization of data is performed via remote copy operations from a primary storage controller to a secondary storage controller, wherein input/output (I/O) requests are received at the primary storage controller from a host both via a bus interface and a network interface while the remote copy operations are in progress. A first data structure stores identification of tracks written via the network interface that are to be copied from the primary storage controller to the secondary storage controller for the synchronization of data. A second data structure stores identification of tracks written via the bus interface that are to be copied from the primary storage controller to the secondary storage controller for the synchronization of data.
