環境

  • ONTAP 9.11.1PXおよび9.12.1
  • SnapMirror
  • Snapshot

問題

  • ONTAP 9.11.1PXおよび 9.12.1を実行しているSnapMirrorデスティネーションボリュームではSnapshotが累積されています
  • 通常、蓄積されるスナップショットはSnapMirrorスナップショットですが、それ以外のスナップショットも蓄積される可能性があります。
  • デスティネーションボリュームがSnapshotの上限に達したため、SnapMirrorジョブが失敗する可能性があります。
  • SnapMirrorポリシーに従っておらず、設定どおりにSnapshotが削除されていません。
  • デスティネーションで次のログが表示され、Snapshotの削除に失敗したことが報告される場合があります。
