環境

  • ONTAP 9
  • NDMP

問題

  • NDMPバックアップが失敗して メッセージが表示されるmaximum number of NDMP processes (36) forked
  • NDMPログのエラーの例:

ERROR: maximum number of NDMP processes (36) forked. Cannot accept connection from IP address: X.X.X.X port 55417 -- closing client [X.X.X.X].55417
ERROR: maximum number of NDMP processes (36) forked. Cannot accept connection from IP address: X.X.X.X port 50552 -- closing client [X.X.X.X].50552
ERROR: maximum number of NDMP processes (36) forked. Cannot accept connection from IP address: X.X.X.X port 53357 -- closing client [X.X.X.X].53357
ERROR: maximum number of NDMP processes (36) forked. Cannot accept connection from IP address: X.X.X.X port 40209 -- closing client [X.X.X.X].40209

 

  • バックアップアプリケーション側で、 server connection to file server...failed   socket connection failedのメッセージ が表示される
  • 他のバックアップが実行中で、新しいバックアップによってmaximum number of NDMP processes   エラーまたはcannot accept connection エラーが発生する場合は、 コマンド system  の出力 services ndmp status にnnセッション数が表示されます。

注: NDMPがNDMPプロセスの最大数に達するための条件は一時的なものになることがあります。NDMPジョブが完了してセッションが解放されると、コマンドを実行するタイミングによってアクティブなセッションの数が変わる場合があります。
