環境

  • VMware vSphere 9.13以前向けのONTAPツール
  • VASA Provider
  • VMware vSphere VVol(仮想ボリューム)

問題

VMwareスナップショット処理は、次の場合に失敗します。

  • VM(VVOLデータストアに配置) にかなり大容量のディスクが多数ある (20+2TBディスク)
  • ボリュームファイルのクローンスプリット負荷「Allowable Split Load」を超えている証拠がある

問題のトラブルシューティングでは、次の動作が表示されます。

  1. VASA Provider(VP)のvvolvp.logで、 clone-token-createVPprepareToSnapshotVirtualVolumeタスクの実行中に次の理由で次の「API呼び出しが失敗します。

[cxf-12345:prepareToSnapshotVirtualVolume-123] NaException com.netapp.offtap3.ontap.ApiFailedException: Failed to create token for node "node01". Reason: Reached maximum split load allowed on the node. (errno=13001)

  1. Snapshot処理の実行中、「Token Reserved Load」が上限に達し、「Allowable Split Load」プールを使い切っています。
