環境

  • ONTAP 9
  • スイッチクラスタ構成(MetroCluster IPを含む)
  • EFOS ファームウェアバージョン <3.9 を実行している BES-53248 スイッチ
  • Cisco Discovery Protocol(CDP)
  • ONTAP クラスタセッションマネージャ( CSM )

問題

  • ONTAP イベントログに CSM.mismatchRemoteDevice エラーイベントが記録されました。

Thu Feb 17 11:52:05 +0100 [node-01: client_common_RPC: csm.mismatchRemoteDevice:error]: CSM connection between source LIF 1023 and destination address 169.254.13.13 might not be optimal for session 00001111deadbeef. The source is currently connected to - remote device and the destination is currently connected to myONTAPCluster remote device.

  • 上記のエラーで参照される IP アドレス、つまり169.254.13.13、このクラスタ内の別のノードのクラスタ LIF です
  • 上記のエラーイベントを報告している影響を受けるノードの Csum Errors CDP ノード統計が表示されます
  • CDP ノードの統計をリセットすると Packets 、カウンタの Packet Per Minute per Cluster-network-port が Csum Errors 同時に上昇し、同時に上昇します
