環境

  • MetroCluster IP
  • Broadcom BES-53248
  • ヘルスモニタリング( HM )

問題

  • BES-53248スイッチを使用するMetroCluster IP構成では cluster peer ping 、スイッチへのすべての接続がオンラインであり、すべてのピアに到達できることが報告されても、次のHMアラートが表示される場合があります。

Cluster-A::*> system health alert show
        Node: Node-A2
      Resource: Node-A2
      Severity: Major
   Indication Time: Mon May 10 17:59:20 2021
      Suppress: false
     Acknowledge: false
   Probable Cause: One or more nodes are not connected to both cluster switches.
   Possible Effect: If one cluster switch fails, "Node-A2" might lose
           access to the cluster.
 Corrective Actions: Verify that the switch "Node-A1" is connected
           to the node "Node-A2". 

  • ノードは、 BES-53248 スイッチに接続されたクラスタポートの CDP / ISDP 情報を取得しません。

  • コマンドで system health alert エラーが表示される
