예: Sun Cluster용 SRDF 복제 그룹 구성
이 예제에서는 클러스터에서 SRDF 복제 설정에 필요한 Sun Cluster 특정 단계를 완료합니다. 이 예제는 다음 작업이 이미 수행된 것으로 가정합니다.
-
어레이 간 복제용 LUN 쌍 만들기 완료
-
저장소 장치 및 클러스터 노드에 SRDF 소프트웨어 설치
이 예에서는 노드가 4개인 클러스터를 호출하며 이 클러스터에는 2개의 노드가 하나의 Symmetrix에 연결되어 있고 다른 2개의 노드가 보조 Symmetrix에 연결되어 있습니다. SRDF 장치 그룹은 dg1라고 합니다.
예 5–15 복제본 쌍 만들기
모든 노드에서 다음 명령을 수행합니다.
# symcfg discover
! This operation might take up to a few minutes.
# symdev list pd
