SwitchFanNotPresent_Alert存在，但交换机日志显示正常状态

适用场景

问题描述

• 客户在两个交换机的EMS日志中收到"SwitchFanNotPresent_Alert "和"SwitchSNMPCommunication_Alert "警报

[Node1: cshmd: hm.alert.raised:alert]: Alert Id = SwitchFanNotPresent_Alert , Alerting Resource = Switch1(serial#)/Fan Module-4 raised by monitor ethernet-switch

• system Health alerts show具有以下警报

        Node: Node-01
      Alert ID: SwitchFanNotPresent_Alert
      Resource: Switch-01(XXXXXXXXXXXX)/Fan Module-3
      Severity: Major
   Indication Time: Wed Nov 22 00:16:34 2023
 Suppress: false
     Acknowledge: false
   Probable Cause: "Fan Module-3" is not inserted properly.
   Possible Effect: Cooling of switch "Switch-01(XXXXXXXXXXXX)" might be
           degraded.
 Corrective Actions: Verify that the fan module is inserted properly.

        Node: Node-01
      Alert ID: SwitchSNMPCommunication_Alert
      Resource: Switch-01(XXXXXXXXXXX)
      Severity: Major
   Indication Time: Wed Nov 22 00:12:06 2023
      Suppress: false
     Acknowledge: false
   Probable Cause: SNMP communication from the node to the ethernet
           switch has failed repeatedly. Invalid SNMP settings
           are configured with ONTAP Switch Health Monitoring or
           on the Ethernet switch.
   Possible Effect: Ethernet switch communication problems and
           accessibility issues.
 Corrective Actions: 1) Check the SNMPv2c community or SNMPv3 username on the Ethernet switch to verify
           that the expected community string or username is configured.
  To view the expected community string or username, run the "system switch ethernet show -snmp-config" command.
  2) (SNMPv3) Verify that the SNMPv3 credentials are present within ONTAP.
           To view the established SNMP logins, run the "security login show -application snmp" command.
           If a custom engine-id was provided for the SNMPv3 user,
           ensure it is same as that of the remote switch.
