CFBMC-7024：主动学习周期期间 AFF C800 低电压关机
问题描述
AFF C800 在 BMC 版本 10.9P1 的主动学习周期中因电池问题而关闭，一旦接管，它就能够完成回馈并上线而不会出现问题。
您可能会看到以下消息：Mon Jun 09 02:10:51 -0500 [<node>: env_mgr: nvmem.battery.voltageLowWarn:alert]: The NVMEM battery voltage is below normal (5600 mV).
Mon Jun 09 02:11:42 -0500 [<node>: env_mgr: nvmem.battery.voltageLow:EMERGENCY]: The NVMEM battery voltage is critically low (5500 mV). To prevent data loss, the system will shut down in 5 minutes.
Mon Jun 09 02:11:52 -0500 [<node>: env_mgr: callhome.battery.warning:alert]: Call home for BATTERY (voltage low) WARNING.
Mon Jun 09 02:12:42 -0500 [<node>: env_mgr: callhome.battery.failure:EMERGENCY]: Call home for BATTERY (voltage low) CRITICAL.
