環境

  • FAS2720
  • ONTAP 9.10.1P7
  • 高度なディスクパーティショニング(ADP)
  • 外部ディスクシェルフ
  • DS212C

回答

  • はい。データ アグリゲートは、ADPを使用して内部ディスクと外部ディスクの両方で作成できます
  • この混乱は、ADP環境におけるルートアグリゲートとデータ アグリゲートの区別から生じました
  • ADPは、FAS2720などのエントリーレベルのプラットフォームでは、デフォルトで内部ドライブのルートパーティションのみをサポートします
  • ただし、初期構成後に追加されたドライブ(外部シェルフディスクを含む)は、ルートアグリゲート用にパーティション分割されませんが、データ アグリゲートには使用できます
  • したがって、データ アグリゲートの作成時にADPディスクと同じRAIDグループに外部ディスクが表示されることは、ONTAPで許可されています

注記:テスト結果に基づくと、内部ディスクと外部ディスクを混在させてデータ アグリゲートを作成する場合、外部ディスクのルート パーティションは、ルート アグリゲートのスペア ディスクとして使用できません
