Red Hat Summit6.3. 호스트와 IP 주소 매핑 확인
다음 명령을 사용하여 어떤 IP 주소가 어떤 호스트와 베어 메탈 노드에 할당되었는지 확인합니다. 이러한 명령을 사용하면 호스트에 직접 액세스하지 않고도 언더클라우드에서 IP 매핑으로 호스트를 볼 수 있습니다.
사전 요구 사항
- 베어 메탈 프로비저닝 서비스가 포함된 성공적인 오버클라우드 배포. 자세한 내용은 3장. 베어 메탈 프로비저닝 서비스를 사용하여 IPv4 오버클라우드 배포 또는 4장. 베어 메탈 프로비저닝 서비스를 사용하여 IPv6 오버클라우드 배포 을 참조하십시오.
절차
다음 명령을 실행하여 각 호스트의 IP 주소를 표시합니다.
