ボリュームで優先度が下がったストレージ効率
環境
- ONTAP 9.3以降
- All Flash FAS(AFF)
- ボリュームレベルの自動バックグラウンド重複排除
問題
- プラットフォーム上の大規模ボリュームでStorage Efficiencyの優先度が解除されました
- ボリューム効率化を有効にしたあとにスペース削減効果が期待どおりにならない
- アラーム受信:
There are volumes that are >15TB's in size which have efficiency savings deprioritised
Triggered Alarm: There are volumes that are >15TB's in size which have efficiency savings deprioritised - warning
