環境

  • Active IQ Unified Manager(AIQUM)9.8+
  • すべてのOSバージョン

問題

  • AIQUMサーバーに時々アクセスできない
  • GUIにアクセスできたとしても、クラスターの取得が断続的に失敗する
  • その結果、AIQUMは現在のONTAPの数値と一致しない古いデータ(例:ディスク容量の使用状況)を表示します
  • au.log 異なるクラスターに対して"Data source is already performing a poll of netappstorageperformance. Therefore this poll is skipped."が複数回発生している
  • これはアップグレード後に発生する可能性があります
  • MySQLerror.logに「server out of memory」レコードが頻繁に記録される
  • 再起動後、問題はしばらくの間解決します
  • 以下のようなエラーが表示される場合があります:
