  • EMS は次の 1 つ以上の健康アラートを報告します。
[Node_01: cshmd: hm.alert.raised:alert]: Alert Id = SwitchUnreachable_Alert , Alerting Resource = SW1(FOCXXXXXXXX)
raised by monitor ethernet-switch
[Node_01: cshmd: hm.alert.raised:alert]: Alert Id = ClusterSwitchConfig_Alert , Alerting Resource = node_01 raised by monitor cluster-switch
[Node_01: cshmd: hm.alert.raised:alert]: Alert Id = SwitchCommunityString_Alert , Alerting Resource = SW1 raised by monitor cluster-switch
  • 出力system health alert show同様に、次の 1 つ以上の内容を示します。

        Node: node-01
      Alert ID: SwitchUnreachable_Alert
      Resource: sw1
   Probable Cause: The ethernet switch's IP address is not reachable from
           the 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: node-01
      Alert ID: ClusterSwitchConfig_Alert
      Resource: node-01
   Probable Cause: One or more nodes are not connected to both cluster
           switches.
   Possible Effect: If one cluster switch fails, "node0-1" might lose
           access to the cluster.
Corrective Actions: Ensure the switch "sw1" is connected
           to the node "node-01".

        Node: node-01
      Alert ID: SwitchCommunityString_Alert
      Resource: sw1
   Probable Cause: Cluster switch "sw1" with IP address
           "123.123.123.123" is not reachable via SNMP. Incorrect
                SNMP community string might be configured on the
                cluster switch.
   Possible Effect: Cluster switch communication problems and
           accessibility issues.
Corrective Actions: Check the SNMP community string on the cluster switch
           to verify the expected community string is configured.
                Use the "system cluster-switch show -snmp-config"
                command to view the expected community string.

  • アラート内のスイッチ名と IP アドレスは、どのクラスタ スイッチにも属していないか、スイッチレス クラスタの場合に報告されています。EMS
  • 指示 system switch ethernet show 空白または不明、またはスイッチを報告IP address not reachable
  • 健全性アラートを削除しても、問題は解決されません。
