ネットワークの問題によるSwitchUnreachable_Alert

• ONTAP 9
• FAS/AFFシステム
• クラスタスイッチ

• AutoSupportから: SwitchUnreachable_Alertがシステムで報告されました

• 1つ以上のノードがクラスタスイッチとの通信に失敗しました
• 以下のコマンドを実行すると、次も表示されます

  • Clsuter::> system health alert show Node: node1 Alert ID: SwitchUnreachable_Alert Resource: switch1(YYY26390XXX) Severity: Major Indication Time: Mon Mar 10 14:42:11 2025 Suppress: false Acknowledge: false Probable Cause: The ethernet switch's IP address is not reachable fromthe local node. Possible Effect: Monitoring of the switch and log collection will not function. Corrective Actions: Ensure that the IP address is reachable or specify the correct reachable IP address. Node: Node1 Alert ID: UnsupportedSwitch_Alert Resource: switch1(YYY26390XXX) Severity: Major Indication Time: Mon Mar 10 14:42:33 2025 Suppress: false Acknowledge: false Probable Cause: Unsupported Ethernet switch is detected. Possible Effect: Communication problems and network connectivity issues occur. Corrective Actions: Unsupported Ethernet switch "undcdsa-nsdb01(FDO26390U4P)" found. Connectsupported Ethernet switch to the network.

• クラスタスイッチはCluster Switch Health Monitor（CSHM）によって監視されていません：

  • ClusterA::> system switch ethernet show
Switch            Type         Address      Model
--------------------------- ------------------ ---------------- ---------------
switch_A_1(xxxxxxxxxxx)    cluster-network   10.1.1.X         NX3132V
   Serial Number: xxxxxxxxxxx
    Is Monitored: false 
      Reason: IP address not reachable
  Software Version: Cisco Nexus Operating System (NX-OS) Software, Version 7.0(3)I4(1)
   Version Source: CDP

• この結果、スイッチの健全性が低下します。
