Abstract
A SCSI ID of a SCSI initiator device that has won an arbitration is identified on a SCSI bus and stored in a register at a SCSI device. Subsequently, a SCSI ID of a selected SCSI target device which was selected by the SCSI initiator device is identified on the SCSI bus and compared with the SCSI ID in the register. If the SCSI ID of the selected SCSI target device and the SCSI ID stored in the register are different, a SCSI command from the SCSI initiator device is processed by the selected SCSI target device. If the SCSI ID of the selected SCSI target device and the SCSI ID stored in the register are the same, the selected SCSI target device refrains from processing the SCSI command from the SCSI initiator device.
