Abstract

본 발명은 SCSI장치들을 구동하고 있는 시스템에서 운영체제의 구성에 관계없이 가동중인 시스템에 SCSI장치를 사용자 수준에서 추가장착하는 방법에 관한 것으로, 처리기보드 및 메모리 보드와 SCSI제어보드로 구성된 시스템의 구성에 있어서 시스템 가동중에 운영체제가 탑재된 메모리 위치에 대한 읽기로 새로이 추가될 장치구동기의 입력정보를 이용하는 단계와, SCSI제어보드로 보내는 메시지 패킷을 가로채어 추가장착할 장치의 특성에 따라 패킷을 변형시키는 단계와, 시스템의 예약영역에 새로이 구성된 저수준의 장치 구동기를 통하여 커널의 일부분으로 탑재시키는 단계와, 사용자의 예외상태에 대한 처리를 위해 시스템 수준으로 전이된 상태에서 재구성된 장치구동기로 제어권을 넘겨 구동기를 기동시키는 제4단계로 이루어지는 특징이있다.The present invention relates to a method for attaching a SCSI device at a user level to a running system regardless of the configuration of an operating system in a system running a SCSI device. The present invention relates to a system consisting of a processor board, a memory board, and a SCSI control board. The system uses the input information of the device driver to be newly added by reading the memory location of the operating system while the system is running, and intercepts the message packet sent to the SCSI control board and transforms the packet according to the characteristics of the device to be added. And mounting it as part of the kernel through the newly configured low-level device driver in the reserved area of the system, and transferring control to the reconfigured device driver in the state transitioned to the system level for handling the exception state of the user. There is a feature consisting of a fourth step of starting.
