Abstract
An initiator device, in a data processing system utilizing a Serial Storage Architecture subsystem, directs an I/O process via secondary path if a primary path is unavailable, even if the primary path is shorter. Also, an initiator device may send outbound data frames, on a secondary path, simultaneously with the SCSI command. Additional flexibility is attained by utilizing an adapter and target storage devices that all support Out of Order Transfers ('OOT'). If a target supports OOT, individual data frames that comprise an I/O process may be sent on multiple paths, allowing greater flexibility in routing. Also, an initiator device may send outbound data frames, on an alternate path, simultaneously with the SCSI command.
