Ndu 預先檢查錯誤: Verify management network redundancy.. ERROR
VPlexcli:/> ndu pre-check Verify management network redundancy.. ERROR VPlexcli:/>ndu pre-check --verbose (***run on Cluster-2) No management connectivity to /engines/engine-1-1/directors/director-1-1-A at IP 128.221.253.35 [ERROR]: No management connectivity to /engines/engine-1-1/directors/director-1-1-B at IP 128.221.253.36 [ERROR]: No management connectivity to /engines/engine-1-2/directors/director-1-2-A at IP 128.221.253.37 [ERROR]: No management connectivity to /engines/engine-1-2/directors/director-1-2-B at IP 128.221.253.38 [ERROR]: No management connectivity to /engines/engine-1-3/directors/director-1-3-A at IP 128.221.253.39 [ERROR]: No management connectivity to /engines/engine-1-3/directors/director-1-3-B at IP 128.221.253.40 [ERROR]: No management connectivity to /engines/engine-1-4/directors/director-1-4-A at IP 128.221.253.41 [ERROR]: No management connectivity to /engines/engine-1-4/directors/director-1-4-B at IP 128.221.253.42 [ERROR]:
Cause
在進一步調查時,可以看到以下行為:
每個 MMCS (MMCS-A 和 MMCS-B) 都可能在 128.221.252 (MMCS-A) 和 128.221.253 (MMCS-B) 網路上,在兩個 VPlex 叢集上 ping 所有導向器。
在這種情況下,(Cluster-1 和 Cluster-2) 上的 MMCS-B 無法 ping 128.221.253 網路上的遠端導向器,但本機導向器會從 128.221.253 網路上的兩個 MMCS-B ping「確定」。
無法透過 SSH 進入叢集 2 上的 MMCS-B....已取代叢集 2 上的 MMCS-B 以解決此問題。
Resolution
已更換 Cluster2 上的 MMCS-B 以解決此問題。
NDU 預先檢查現已清理乾淨,沒有錯誤。
Additional Information
重新整理 VS6 的 MMCS IP 資訊
Cluster-1 MMCS-A 128.221.252.33 Cluster-1 MMCS-B 128.221.253.33 Cluster-2 MMCS-A 128.221.252.65 Cluster-2 MMCS-B 128.221.253.65
