環境

  • ONTAP Tools for VMware vSphere ( OTV ) 9.8
  • ONTAP Tools for VMware vSphere ( OTV ) 9.10

問題

デバイス検出をトリガーするVMware Site Recovery Manager(SRM)処理を実行すると、次の状況が発生します。

  • 処理に予想よりも時間がかかります
  • discoverDevices操作の大部分は、FlexVol QoSポリシーグループの解析に使用されます

たとえば、vvolvp.logには、次のイベントが表示され、QoSポリシーグループの評価例が示されます。QoSポリシーグループが割り当てられているFlexVolの数に基づいて、この解析には長い時間がかかり、数千イベントではない場合は数百を含むことがあります(読みやすさを考慮して線が途切れます)。
