系统健康警报中报告了不存在交换机的 ClusterSwitchConfig_Alert

适用场景

• ONTAP 9
• 集群交换机运行状况监控器(CSHM) AutoSupport消息

问题描述

• 交换机子系统健康状况下降：

cluster1::> system health subsystem show
Subsystem      Health
----------------- ------------------
SAS-connect     ok
Environment     ok
Memory       ok
Service-Processor ok
Switch-Health    degraded
CIFS-NDO      ok
Motherboard     ok
IO         ok
MetroCluster    ok
MetroCluster_Node ok
FHM-Switch     ok
FHM-Bridge     ok
SAS-connect_Cluster ok

• EMS 报告以下一个或多个健康警报：

• 输出system health alert show类似地显示以下一项或多项内容：

        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.

• 警报中的交换机名称和 IP 地址不属于任何集群交换机，或在无交换机集群的情况下报告。EMS
• 命令 system switch ethernet show 为空白或未知，或报告切换IP address not reachable。
• 删除运行状况警报不会解决问题描述问题。
