스마트 테스트는 정상이므로 고온 문제와 관련이 없다고 결론지을 수 있습니다.
경우에 따라 단일 FSC의 드라이브 중 하나 또는 둘 다 Invalid Partition 또는 image 상태로 이동합니다.
단일 FSC의 드라이브에 있는 수퍼 콘덴서가 실패할 경우 이 오류가 발생할 수 있습니다.이 오류는 드라이브가 교체되거나 FSC에서 발생하는 영구 드라이브 오류이므로 복구할 수 없습니다.
자세한 내용은 Cisco TAC에 문의하십시오.
어떤 드라이브에서도 이것이 확인되면 해당 드라이브에 슈퍼 콘덴서 장애가 발생합니다.
이러한 로그는 활성 MIO(Management Input/Output Card)의 디버그 콘솔 로그에 표시됩니다.
