FAS/AFF 平台
实时时钟(Real-Time Clock、RTC)币形电池

问题描述

节点和机箱故障 LED 亮起，但没有清晰的故障指示
或者，系统将生成以下 EMS 消息，并报告电池出现非严重故障：

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 show P3.3v 电池为 []warnlow

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

SP-LATEST-SYSLOG log show [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

在 BMC/SP 中，我们将看到以下非严重情况：
