Ndu 预检查错误: 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
在进一步调查时,可以看到以下行为:
每个 MMCS(MMCS-A 和 MMCS-B)都可以对 128.221.252 (MMCS-A) 和 128.221.253 (MMCS-B) 网络上两个 VPlex 群集上的所有控制器执行 ping 操作。
在这种情况下,两者(群集 1 和群集 2)上的 MMCS-B 无法 ping 128.221.253 网络上的远程控制器,但本地控制器从 128.221.253 网络上的两个 MMCS-B ping 正常。
无法通过 SSH 连接到群集 2 上的 MMCS-B....已替换群集 2 上的 MMCS-B 以解决此问题。
Resolution
更换了 Cluster2 上的 MMCS-B 以解决此问题。
NDU 预检查现在干净且无错误。
Additional Information
重新概括 VS6 的 MMCS IP 信息
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
