255個を超えるSnapshotを含むFlexVol をFlexGroup に変換する方法

環境

• ONTAP 9
• FlexGroup

説明

• ONTAP 9.7では、FlexVol をFlexGroup に変換できます
• ただし、ONTAP 9.7では
  • FlexGroup でサポートされるSnapshotの数は255個未満です
  • FlexVolでサポートできるSnapshotの最大数は1023です。

ONTAP 9.7のリリースで255個を超えるSnapshotを含むFlexVol を変換すると、次のエラーがスローされます。

Error: command failed: Cannot convert volume "myvol" in Vserver "svm1" to a
       FlexGroup. Correct the following issues and retry the command:
       * The volume has more than 254 snapshot copies.  Use the "volume
       snapshot show -vserver svm1 -volume myvol" command to list the Snapshot
       copies present on the volume and remove one or more of them with the
      "snapshot delete -vserver svm1 -volume myvol" command.

       * The volume has Snapshot copies with IDs greater than 255.  Use the
       (privilege: advanced) "volume snapshot show -vserver svm1 -volume myvol
       -logical-snap-id >255 -fields logical-snap-id" command to list the
       Snapshot copies with IDs greater than 255 then delete them using the
      "snapshot delete -vserver svm1 -volume myvol" command.
