Abstract
A primary storage controller receives a write command from a host, wherein Fiber Channel frames corresponding to the write command have a priority indicated by the host. The primary storage controller performs a synchronous copy operation to copy data written by the write command from the primary storage controller to a secondary storage controller, wherein Fiber Channel frames corresponding to the synchronous copy operations have an identical priority to the priority indicated by the host.
