适用于

  • FAS/AFF 平台
  • 实时时钟 (RTC) 纽扣电池

问题描述

  • 节点和机箱故障指示灯亮起,出现以下错误:

hsamcmd --fault-show-all
===============================
tag  origin  fld                    fault reason                   count  time
---- ------- ----                   -------------                   ------ -----
1   bmc    /chassis-1/controller-a          P3V3_BATT: Voltage Sensor 26 LNC         1    Wed Jun 25 10:58:10 2025
2   bmc    /chassis-1/controller-a          P3V3_BATT: Voltage Sensor 26 LCR         1    Wed Jun 25 10:58:22 2025

  • 或者,节点和机箱故障 LED 点亮,但没有明确的故障指示
  • 以下 EMS 消息,并将针对电池报告非关键故障:

Tue Sep  4 15:05:29 CEST [NODE1:monitor.chassisPower.degraded:warning]: Chassis power is degraded: RTC Battery is in WARN LOW state current voltage is 2774 mV, normal low is 2800 mV

  • SP-LATEST-IPMI log shows P3.3V Batt 为以下条件。

P3.3V Batt   warnlow  2660 mV    2537 mV    2695 mV    3307 mV    3447 mV   

P3.3V Batt    critlow   945 mV    2100 mV    2205 mV    3395 mV    3500 mV

  • SP-LATEST-SYSLOG 日志显示rtcWarnLowPower

BMC env_mgr[1534]: Payload EMS: EMS_monitor_rtcWarnLowPower(2660 mV) 

  • BMC events all显示P3.3V Batt is critical low

BMC env_mgr[1461]: P3.3V Batt is critical low

  • 从 BMC/SP 显示 P3V_BAT 是以下条件:

Sensor Name    | Current   | Unit     | Status    | LCR     | LNC     | UNC     | UCR
-----------------+------------+------------+------------+-----------+-----------+-----------+-----------
P3V_BATT      | 2.840    | Volts    | nc      | 2.720    | 2.880    | 3.300    | 3.460
Or
P3V3_BATT     | 0.963    | Volts    | cr      | 2.100    | 2.205    | 3.395    | 3.500
