環境

  • ONTAP 9
  • コンピュータ支援3次元インタラクティブアプリケーション(CATIA)
  • DFS(Distributed File System;分散ファイルシステム)
  • CIFS

問題

  • CATIAはDFS経由で共有にアクセスしており、サーバーアクセスをランダムに変更しています
  • DFSはコストに基づいてロケーションアクセス用に設定されているが、突然変更されている
  • TCPダンプで次のようなエラーが表示される'STATUS_OBJECT_NAME_NOT_FOUND'
  • ONTAPには 、CATIAによって生成された多数の匿名セッションログインが表示されます。
