環境

  • ONTAP FCP

問題

  • FCホスト/クライアントはLUNにはアクセスできないが、他のホストはアクセスできない
  • アクセス権を持つホストがパフォーマンスの問題の影響を受ける
  • Microsoft Hyper-V システムログレポートイベントID 153
  • Microsoft Hyper-Vデバイスマネージャから、ストレージアダプタのHBAポートが不明なステータスで「This device is not functioning correctly」と報告される
  • ONTAPイベントログは、数分ごとに FC IOエラー状態= 5 および AEN 0x8048エラーを報告します。
  • ONTAP ASUPと監視機能がFCポートSFP送信光パワーが半分に低下したことを示している
ONTAPイベントログの例:
Cluster::*> event log show -message-name *fcp*
