ネットワークの問題によるSwitchUnreachable_Alert
環境
- ONTAP 9
- FAS / AFFシステム
- クラスタスイッチ
問題
- AutoSupportから： SwitchUnreachable_Alertがシステムに報告される

undcdsa-fasb12::> system health alert show Node: undcdsa-fasb12 Alert ID: SwitchUnreachable_Alert Resource: undcdsa-nsdb01(FDO26390U4P) 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: undcdsa-fasb12 Alert ID: UnsupportedSwitch_Alert Resource: undcdsa-nsdb01(FDO26390U4P) 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.
