CFBMC-7024：AFF C800 在主动学习周期中因电压过低而关闭
问题描述
在 BMC 版本 10.9P1 上，AFF C800 在主动学习周期中因电池问题而关闭，一旦接管，它就能完成恢复并顺利上线。
您可能会看到类似以下内容的消息：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.
Mon Jun 09 02:16:42 -0500 [<node>: env_mgr: monitor.shutdown.emergency:EMERGENCY]: Emergency shutdown: Environmental Reason Shutdown (Battery voltage critical)
Mon Jun 09 05:10:52 -0500 [<node>: cf_main: cf.fsm.takeoverByPartnerEnabled:notice]: Failover monitor: takeover of <node> by <partner_node> enabled
Mon Jun 09 05:10:53 -0500 [<node>: statd: monitor.nvramLowBattery:EMERGENCY]: NVRAM battery is dangerously low.
Mon Jun 09 05:10:53 -0500 [<node>: statd: monitor.nvramLowBattery.notice:notice]: If the NVRAM battery is dangerously low, the system shuts down automatically every 24 hours to encourage you to replace it. If you reboot the system it will run for another 24 hours before shutting down.
