适用场景

  • 光纤 MetroCluster
  • ONTAP 9
  • 从 AFF-A300 到 AFF-A400 的标题交换

问题描述

  • 完成 MetroCluster 中第一个站点的机头交换后,完成第一个切回后,切换模拟将失败

示例:

ClusterA::*> metrocluster operation show
    Operation: switchover-simulate
      State: failed
    Start Time: 2/19/2022 22:19:52
     End Time: 2/19/2022 22:19:57
      Errors: Failed to validate the node and cluster components before the switchover operation.
          ClusterB::ClusterB-01 (non-overridable veto): DR partner NVLog mirroring is not online.
          ClusterB::ClusterB-02 (non-overridable veto): DR partner NVLog mirroring is not online.

  • 尽管 FCVI 设备状态为 " 已启动 " ,但 DR 镜像也报告为脱机
