An apparatus includes a non-volatile memory media and a storage controller. The storage controller is configured to fetch a storage command from a submission queue of a host. The submission queue has a submission queue identifier (SQID). The storage controller then determines a submission queue fetch error in response to receiving a Transport Layer Packet (TLP) error as a result of fetching the storage command. Next, the storage controller is configured to determine a command identifier (CID) for the storage command associated with the submission queue fetch error. The storage controller then sends a completion message to the host. The completion message uniquely identifies the storage command of the submission queue associated with the submission queue fetch error using the SQID and CID.
