Disaster Recovery
- Switch 노후화 / 장애발생으로 무한 재부팅으로 인하여 정상 부팅 불가 시, Run Rescue으로 복구하기
USB에 아래와 같이 폴더 구성 및 파일 넣기
* USB Recovery를 지원하는 USB가 별도로 존재하지는 않으나, 흔하지 않음
필자는 4GB / 16GB 두 개 사용
/usb/장비이름(ex 6560)/certified/*.img
/usb/장비이름(ex 6560)/working/*.img
/usb/Nrescue.img
root 폴더에 Nrescue.img 파일을 넣을 것
* 기종별 복구 이미지가 다르니, 주의하여 넣을 것.
USB안에 폴더 구조 / 이미지 파일 / 장비에 맞는 복구 파일만 잘 맞으면 정상 동작
u-boot 모드 진입 후, run rescure만 입력하면 자동 복구 및 재부팅으로 공장 초기화 가능

To use the switch rescue procedure first make sure of the following:
- The Urescue.img file is located in the root directory of the
USB flash device
- The 6860 directory contains all the system files required to
revive the switch.
i.e. 6860/certified/<*.img boot.cfg>
on the USB flash device
- USB flash device is inserted
Once the above requirements are met, issue the following command
at the prompt to start the rescue process:
=> run rescue
***** Using the rescue process WILL destroy all switch data *****
***** USE WITH EXTREME CAUTION *****

Rescue Utility v2.0
The Rescue Utility reformats the switch compact flash memory.
All files in compact flash will be lost and replaced with the
contents of the /usb/6860/* from the USB storage device.
This will take at least 10 minutes.
