CSHM 报告的 "SwitchFanNotPresent _Alert" 用于 Cisco 集群网络交换机

 

适用场景

Cisco 集群网络交换机

问题描述

对于集群网络交换机的所有风扇模块, CSHM 报告了以下 "SwitchFanNotPresent_Aler" :

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]

发生原因

  • 当集群交换机无法获取与风扇相关的信息时,可能会发生此问题。
  • 集群交换机运行状况监视器( CSHM )只能检测到当交换机查询无法返回有关所有风扇或电源的信息时、风扇或电源是否丢失。

解决方案

  • 检查 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

  • 通过运行以下命令登录到两个集群交换机并验证所有风扇模块是否均处于良好运行状态:

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且警报自行清除、则可以安全地忽略此事件、无需执行任何进一步操作。
