MDS 9148S 및 MDS 9250i의 커널 패닉으로 인해 스위치를 사용할 수 없습니다.

Summary: 'sysmgr' 서비스 장애로 인해 스위치를 사용할 수 없는 커널 패닉이 발생합니다. 'sysmgr' 서비스 충돌은 HA(High Availability) 정책 재설정 또는 기타 시스템 장애와 같은 이벤트에 의해 트리거될 수 있습니다. 그러나 이러한 발생은 일상적인 이벤트가 아닙니다.

Cause

'sysmgr' 서비스 충돌은 MDS 릴리스 8.1(x)~8.3(x)을 실행하는 MDS 9148S 및 MDS 9250i 플랫폼에서 발생합니다. 커널 패닉이 발생하여 전체 스위치를 사용할 수 없게 됩니다. 따라서 기능을 복원하려면 시스템을 강제로 다시 로드해야 합니다. 커널 패닉으로 인해 'sysmgr' 서비스가 종료된 정확한 이유를 확인할 수 없습니다.

Resolution

해결:
이 문제를 완화하기 위한 알려진 해결 방법은 없습니다. 하지만 스위치를 다시 로드하여 사용할 수 없는 상태를 해제합니다. 

해상도:
TAC의 제안은 코드를 버전 8.4(2f)로 업그레이드하는 것입니다.
