问题描述

事件日志中报告了以下电池警报：

[Node-01: env_mgr: nvmem.battery.capLow:alert]: The NVMEM battery capacity is low (1 cycles).

[Node-01: env_mgr: nvmem.battery.fccLowCrit:EMERGENCY]: The NVMEM battery full-charge capacity is critically low (15 ). To prevent data loss, the system will shut down in 20 minutes.

[Node-01: env_mgr: callhome.battery.warning:alert]: Call home for BATTERY (remain capacity critical low) WARNING.

[Node-01: env_mgr: callhome.battery.failure:EMERGENCY]: Call home for BATTERY (full capacity critical low) CRITICAL.

[Node-01: statd: monitor.nvramLowBattery:EMERGENCY]: NVRAM battery is dangerously low.

[Node-01: 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.

[Node-01: statd: callhome.battery.low:alert]: Call home for BATTERY_LOW.

[Node-01: statd: monitor.shutdown.nvramLowBattery.pending:alert]: NVRAM battery is dangerously low. Halting system in 24 hours. Replace the battery immediately!

如果未采取任何操作，则节点每 24 小时重新启动一次，并显示以下事件：

[Node-01: env_mgr: monitor.shutdown.emergency:EMERGENCY]: Emergency shutdown: Environmental Reason Shutdown (BATTERY (full capacity critical low) for 20 mins)

[Node-01: env_mgr: nvmem.battery.capNormal:notice]: The NVMEM battery capacity is normal. [Node-01: statd: monitor.nvramLowBattery:EMERGENCY]: NVRAM battery is dangerously low. [Node-01: 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. [Node-01: statd: callhome.battery.low:alert]: Call home for BATTERY_LOW.
