      1. usb 마운트
      mount -t msdosfs /dev/da1s1 /mnt  

// da1s1은 usb연결 로그 확인하여 올라오는 usb명으로 수정 필요
// 마운트를 굳이 mnt에 하지 않아도 됨
      1. 마운트 된 /mnt 내 OS파일 장비 내부 저장소로 복사
      // 1. 옮길 폴더 생성
mkdir /tmp/os
// 2. 파일 복사
cp /mnt/junos~~~.tar /tmp/os/junos~~~.tar
      1. usb umount
      umount -f /dev/da1s1 of umount -f /mnt

// da1s1은 마운트 됐던 usb명으로 맞춰야함
      1. OS업그레이드
      request system software add /tmp/os 파일명 force no-validate reboot

    • 참고사항

      • /tmp폴더에 폴더 생성 후 OS파일 옮겨 OS업그레이드 시 완료후에 생성한 폴더까지 삭제됨 → tmp는 임시폴더라 재부팅 후 내용 삭제됨
      • /var/tmp에 폴더 생성 후 OS파일 옮겨 OS업그레이드 진행 시 폴더는 남아있으나 OS파일은 압축해제 후 삭제됨 → 임시 생성한 폴더 삭제 필요
