Cisco 集群网络交换机

问题描述

CSHM 针对集群网络交换机的一个或多个风扇模块报告“SwitchFanNotPresent_Alert”：

Wed Apr 29 15:53:23 AEST [nodename: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process cshm: SwitchFanNotPresent_Alert[switch(XXXXXXXXXXX)/Fan Module-1]. Wed Apr 29 15:28:23 AEST [nodename: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process cshm: SwitchFanNotPresent_Alert[switch(XXXXXXXXXXX)/Fan Module-2]

CSHM 针对集群网络交换机的一个或多个 PSU 报告“SwitchPowerNotPresent_Alert”：

Wed Apr 29 15:28:23 AEST [nodename: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process cshm: SwitchPowerNotPresent_Alert[switch(XXXXXXXXXX)/PowerSupply-1].

发生原因

当集群交换机无法提取风扇相关信息时、可能会出现此问题描述。
只有在对交换机的查询无法返回有关所有风扇或电源的信息时、集群交换机运行状况监控器(CSHM)才能检测到风扇或电源缺失。

解决方案

检查在CSHM报告警报期间是否执行了任何维护活动
在事件日志中验证警报是否在一段时间后清除：

cluster::> event log show Time Node Severity Event ------------------- ---------------- ------------- --------------------------- 4/29/2020 15:49:12 nodename ALERT hm.alert.raised: Alert Id = SwitchFanNotPresent_Alert , Alerting Resource = switch(XXXXXXXXXXX)/Fan Module-1 raised by monitor cluster-switch 4/29/2020 16:10:20 nodename NOTICE hm.alert.cleared: Alert Id = SwitchFanNotPresent_Alert , Alerting Resource = switch(XXXXXXXXXXX)/Fan Module-1 cleared by monitor cluster-switch

运行以下命令、登录到这两个集群交换机并验证所有风扇模块是否均运行良好：

Switch>enable Switch#show environment fan detail Fan: --------------------------------------------------------------------------- Fan Model Hw Direction Status --------------------------------------------------------------------------- Fan1(sys_fan1) NXA-FAN-30CFM-F 0.0 front-to-back Ok Fan2(sys_fan2) NXA-FAN-30CFM-F 0.0 front-to-back Ok Fan3(sys_fan3) NXA-FAN-30CFM-F 0.0 front-to-back Ok Fan4(sys_fan4) NXA-FAN-30CFM-F 0.0 front-to-back Ok Fan_in_PS1 N2200-PAC-400W -- front-to-back Ok Fan_in_PS2 N2200-PAC-400W -- front-to-back Ok Fan Zone Speed: Zone 1: 0x32

如果这是一次性事件、并且警报已自行清除、则可以安全地忽略此事件、无需采取进一步操作。
如果警报仍然存在、请尝试从监控中删除交换机、然后重新添加交换机以再次轮询传感器：

::> system switch ethernet delete -device <switch_name>

::> system switch ethernet create -device <switch_name> -address <ip_address> -snmp-version <version> -community-or-username cshm1! -model OTHER -type cluster-network
