Ubuntu 에서 Dell Raid Controller 를 다루려면 아무래도 이것저것 신경이 쓰인다.
그걸 그냥 놓치고 있자니 디스크가 언제 Fail 날지도 모르고, 매주 방문해서 쳐다보고 있기도 뭐하고...
다음의 URL 을 참고해서 관리툴을 설치하자!

#/etc/apt/sources.list 에 다음의 내용 추가 (물론 각자 패키지에 맞게 수정 요함)
"deb http://hwraid.le-vert.net/ubuntu precise main"
그 다음엔 패키지 키 추가
wget -O - http://hwraid.le-vert.net/debian/hwraid.le-vert.net.gpg.key | sudo apt-key add -
그리고 실제 패키지 설치
apt-get install megacli megactl megaraid-status
그러면 다음과 같은 명령어들을 쓸수 있게 된다.
# megacli -LDInfo -Lall -aALL
# megacli -PDList -aALL
# megacli -AdpEventLog -GetEvents -f logfile -aALL
이 명령어들을 어떻게 봐야 하냐고? 그건 직접 보셔야 할 듯..
그치만 다행이(?) Fail 난 로그 하나를 여러분께 나눌 수 있게 되어 나눕니다~
