A first storage system in one illustrative embodiment is configured to participate in a replication process with a second storage system. Each of a plurality of storage nodes of the first storage system comprises a plurality of storage devices and a set of processing modules configured to communicate with corresponding sets of processing modules on other ones of the storage nodes. In conjunction with the replication process, a first one of the processing modules is configured to generate a request message for transmission to a second one of the processing modules requesting that the second processing module transfer designated replication data to the second storage system. The request message comprises a unique message identifier that the second processing module incorporates into a subsequent response message transmitted back to the first processing module to indicate a result of the requested transfer of the designated replication data to the second storage system.
