고재진님 답변 주셔서 감사드립니다.
11.31에서 (1번)두개의 서버는 클러스터 , RAC가 구성
(2번)다른 두개의 서버는 클러스터만 구성하려고 합니다.
(문제)1번과 2번에 각각 두개씩의 lock device를 만들려고
합니다.
ioscan -mdsf 명령어로 disk 정보를 확인 해보면 아래와 같이 보여집니
다.
(1번)
nesbdbd1:/>ioscan -mdsf

nesbdbd1, nesbdbd2서버에서 lock device로 사용할 부분은
/dev/rdisk/disk113, /dev/rdisk/disk114이고
nmdbd1, nmdbd2 서버에서 lock device로 사용할 부분은
nmdbd1(/dev/rdisk/disk43, /dev/rdisk/disk49),
nesdbdb2(/dev/rdisk/disk43, /dev/rdisk/disk45)입니다.
1개의 disk가 4개의 path로 보임.
위와 같은 경우에는 lock device를 어떻게 생성해야할지 모르겠습니
다.
도움 부탁드립니다. 자세히 알려주시면 감사드리겠습니다.
