環境

  • ONTAP
  • ファイバチャネルプロトコル(FCP)

問題

  • ファブリック変更時に複数のストレージFCポートをSRAMダンプでリセット
  • 複数のVMwareホストを使用するLUNのスキャンFCポートがSRAMダンプでリセットされる
  • SRAMダンプによるファブリックステート変更通知(SCN)FCポートのリセット
  • 複数のStorage vMotion FCポートがSRAMダンプでリセットされる
  • SRAMダンプを使用したVMwareデータストア原因FCポートのリセットの追加または削除
  • リセットしてステータスをクリアします0x87800000 status1 0xbcbf status2 0x4
  • フレームタイムアウトには、受信(Rx)または送信(Tx)/送信元(SID)または宛先(DID)としてISLが常に関与します。
