環境

問題

• 2ノードスイッチレスクラスタのイベントログでは、次のアラートが報告されます。

[Node-1: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process cshm: SwitchCommunityString_Alert[cluster-stor-sw2(XXXXXXXXXX)].

[Node-1: cshmd: hm.alert.raised:alert]: Alert Id = UnsupportedSwitch_Alert , Alerting Resource = cluster-stor-sw2(XXXXXXXXXX) raised by monitor ethernet-switch

• system health alert showコマンド出力には、次の情報が表示されます。

                Node: Node-1
          Monitor: ethernet-switch
          Alert ID: SwitchCommunityString_Alert
     Alerting Resource: cluster-stor-sw2(XXXXXXXXXX)
         Subsystem: Switch-Health
      Indication Time: Fri Nov 04 07:07:04 2022
     Perceived Severity: Major
       Probable Cause: Configuration_error
        Description: Ethernet switch "cluster-stor-sw2(XXXXXXXXXX)" with IP address "10.X.XXX.XXX" is not reachable via SNMP. Incorrect SNMP community string might be configured on the Ethernet switch.
     Corrective Actions: Check the SNMP community string on the Ethernet switch to verify that the expected community string is configured. Use the "system switch ethernet show -snmp-config" command to view the expected community string.
      Possible Effect: Ethernet switch communication problems and accessibility issues.
 

            Node: Node-1
          Monitor: ethernet-switch
          Alert ID: UnsupportedSwitch_Alert
     Alerting Resource: cluster-stor-sw2(XXXXXXXXXX)
         Subsystem: Switch-Health
      Indication Time: Fri Nov 04 07:07:04 2022
     Perceived Severity: Major
       Probable Cause: Configuration_error
        Description: Unsupported Ethernet switch is detected.
     Corrective Actions: Unsupported Ethernet switch "cluster-stor-sw2(XXXXXXXXXX)" found. Connect a supported Ethernet switch to the network.
      Possible Effect: Communication problems and network connectivity issues occur.
