[손창헌]

수고하십니다.

o/s mirror가 구성이 되었있었는데 mirror구성이 깨진것 같습니다.

log내용과 mirror깨진게 상관이 있는지 모르겠습니다.



복구를 해야야하는데 방법을 주시면 감사하겠습니다.

[고재진]

안녕하세요.

로그내용이 좀 이상하네요.



우선



00000 /dev/dsk/c2t1d0s2 01032 current



이부분으로 짐작컨데 미러가 되어있지 않습니다.

단순히 vgextend 만 걸어 놓은것 같네요.

미러가 걸려있으면 /dev/dsk/c2t0d0 정보와 stale 이라는 메세지가 있어야 됩니다.

그리고 syslog 에도 디스크가 깨졌다는 메세지는 없습니다.



Feb 29 08:52:26 mp1 vmunix: 0/4/1/0: Unable to access previously accessed device at nport ID 0x10100



ioscan 으로 0/4/1/0 부분의 디스크가 어떻게 보이는지 모르겠습니다.

혹시 controller나 fc카드를 바꾼적이 있으신지 궁금합니다.

위메세지는 컨트롤러쪽이나 fc 카드의 정보가 바뀌었을때 나오는 메세지입니다.



#fcmsutil /dev/fcd_ replce_dsk 0x10100

(fcd or td)



이렇게 하시면 에러는 없어질것 같습니다.

[양계전]

mp1:/] strings /etc/lvmtab

/dev/vg00

/dev/dsk/c2t1d0s2

/dev/dsk/c2t0d0



미러가 아닌듯 싶습니다



보통

/dev/vg00

/dev/dsk/c2t1d0s2

/dev/dsk/c2t0d0s2

이래야 맞습니다



0/4/1/0 쪽 hba path 쪽이 문제 있어 보입니다.

[손창헌]

답변 감사합니다.

그럼 이 상태에서 미러 구성을 걸어주기만 하면 되는건가요?

그리고,fc 카드를 추가하거나 제거,이동 한적은 없었습니다.

[고재진]

안녕하세요.



fc 카드로그는 아무 문제 없었다면 fcmsutil 명령어로 없애시면 됩니다. fc카드,san switch 포트, storage controller 등에서 문제(?)가 생겼을때 나옵니다.



제가 보기엔 미러는 다시거는게 좋을것 같습니다.

ia 서버는 미러거는게 조금 틀리니까..

제대로 걸려있는지 확인 하는 절차보다 다시거는게 좋을것 같네요.
