  • Unified ManagerでLUNのパフォーマンスレポート Free Capacity をダウンロードすると、列に負の値が表示されます。

  • Used Sizeこれは、の値 size (LUNの元のサイズに属する)よりも大きい場合に想定される動作です。 

  • Unified Managerは、レポートの使用可能なサイズを(サイズ)-(サイズ使用)=空き容量として設定します。

例:
 
 <CModeLUN UUID="xxxxxx-xxxx-xxxx-xxxxx-xxxxxxx" VolumeRef="VOL_TEST" VserverRef="SVM!" Path="/vol/vol_test/vol_test" IsOnline="true" Size="1869169767424" SizeUsed="1869605892096" IsSpaceReservationEnabled="false" IsSpaceAllocEnabled="false" IsMapped="true" SerialNumber="xxxxxxxxxxxx" MultiProtocolType="windows_2008" Alignment="ALIGNED" AlignmentRaw="aligned" PrefixSize="0" SuffixSize="0" Class="REGULAR" ClassRaw="regular" /> (Size="1869169767424") - (SizeUsed="1869605892096") = -436124672 (-0.406)
