環境

  • NetApp ONTAP(9.x以降、clustered Data ONTAP)
  • Trident/Trident Protect
  • DRにTrident Protectを使用するKubernetes/OpenShiftクラスター
  • Trident Protectによって管理されるSnapMirror XDP関係

問題

  • Kubernetes/OpenShift環境で災害復旧向けにTridentProtectを設定した後、デスティネーションのStorage Virtual Machine(SVM)上にSnapMirror関係が作成されますが、それらは「Uninitialized/Idle」状態のままとなり、「Established」状態に移行しません。
  • その結果、DR用のデータレプリケーションが機能しません。
