ioscan관련 질문

[이종선]

미러를 걸은 상태입니다.

하지만 ioscan 으로 확인할때 이렇게 나옵니다 왜 그런건가요 os가 깔린 디스크가 2개 보여야 되는거 아닌가요??

서버는 슈퍼돔이구요 o/s는 11.31입니다.

똑같은 조건에 다른 서버에서 확인할경우 ioscan -nfC disk, ioscan -m lun 에서 os가 깔린 디스크가 보이고 미러가 된 디스크도 보입니다. 아래의 경우는 보이지 않는 경우입니다.

안녕하세요.



미러는 어떻게 구성했는지 궁금하네요.



우선 어느 디스크인지 확인을 해야 될것 같네요.



strings /etc/lvmtab 명령어로 어떤디스크인지 확인을 해보세요.



insf -eCdisk 로 device 파일을 설치해보시구여.



그럼.

[정우익]

어떤 Disk 가 Mirror 걸려있는지 확인 하는 것은

ioscan 으로도 확인 하지만



lvlnboot -v , strings /etc/lvmtab등으로 확인해 봐야 할 것입니다.



위의 명령어와 아래의 명령어에 따른 상태를 보면 Disk number가 다른 것을 확인 할 수 있겠네요...



ㅋㅋㅋㅋㅋㅋ

종선 잘 지내고 있는 지 열심히 일하고 열심히 물어보고 있구나..

수고...
