環境

  • ONTAP 9.6以降
  • FabricPool
  • ボリューム移動 

回答

ONTAP 9.6以降では、ボリューム移動のデスティネーションローカル階層がソースローカル階層と同じバケットを使用する場合、 
バケットに格納されているソースボリューム上のデータがローカル階層に戻されません。 
この最適化されたボリューム移動により、ネットワーク効率が大幅に向上します。

ONTAP 9.12.1までは、mgwdログで次の情報を探して、ボリューム移動が最適化されたかどうかを確認します。

ONTAP 9.12.1以降では、ボリューム移動が最適化されたかどうかに関係なく、EMSエントリが報告されます。

mgmtgwd.volmove.notoptimized: Volume move operation from source aggregate "aggr3" to destination aggregate "aggr2" of volume "vol1" on Vserver "vs1" might need to copy data from existing objects in the capacity tier.
mgmtgwd.volmove.optimized: Volume move operation from source aggregate "aggr2" to destination aggregate "aggr1" of volume "vol1" on Vserver "vs1" avoided copying data from existing objects in the capacity tier.
