CentOS 6에서 Intel 10G NIC에서 지원되지 않는 SFP+ 모듈 사용하기



Environment
  • CentOS 6.4 (64bit)
  • Dell OEM Intel 10GB Dual Port NIC
최신 드라이버 설치
tar zxvf ixgbe-3.15.1.tar.gz -C /tmp
cd /tmp/ixgbe-3.15.1/src
make install

드라이버 언로드 및 로드

rmmod ixgbe
modprobe ixgbe allow_unsupported_sfp=1
allow_unsupported_sfp 는 테스트되지 않은 SFP+ 모듈을 로드될 수 있도록 해주는 parameter이다. 하지만 테스트되지 않았기 때문에 안정성은 장담할 수 없다는 것을 명심하자.

Configuration



Spacewalk는 설정 파일들을 관리하고 배포할 수 있도록 해주는 기능을 제공한다. 이 기능을 이용하면 공통적으로 적용되어야 할 파일들을 리비전 기능을 통해 쉽게 관리할 수 있다.

  • Configuration Channel 등록

    설정 파일들을 관리할 채널을 새로 생성하여 설정파일을 넣도록 한다.
    Name
    Default Configurations Channel
    Label
    default-configs-channel
    Description
    Default Configuration Channel
    다음은 채널을 등록한 화면이다.
  • Configuration File 추가

    Add Files 링크를 클릭하여 새로운 설정 파일을 등록한다. 이 설정 파일은 로그인 했을 때 보여줄 메시지를 담는 파일로 /etc/motd 라는 경로를 갖는다.
Need Package
서버에서 각 시스템(클라이언트)에게 등록된 Configuration Channel을 적용시키기 위해서는 클라이언트에 rhncfg-action 패키지가 설치되어있어야 함.

GUI


  • GUI는 동기화 진행사항을 확인 할 수 없음 단, /var/log/rhn/reposync/<Channel Label>-<시간>.log 로그 파일로 확인 가능함
  • RPM 저장소 위치는 다음 위치에서 설정가능

  • 특정 채널의 특정 패키지만을 동기화 할 수 없으므로 전체 동기화에 따른 디스크 용량을 반드시 고려해야함
