環境

  • ファブリックMetroCluster
  • ONTAP 9
  • AFF-A300 から AFF-A400 へのヘッド交換が可能です
  • AFF-A700 / FAS9000からAFF-A900 / FAS9500へのヘッドスワップ

問題

  • MetroCluster の最初のサイトのヘッド交換が完了したあとで最初のスイッチバックを完了すると、スイッチオーバーのシミュレーションは失敗します

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.

  • FCVI デバイスステータスが「 up 」のときにも DR ミラーリングがオフラインになっていると報告されます。
