- イベントログには、次のバッテリアラートが報告されます。例:
[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!
- 何も対処しない場合、ノードは24時間ごとにリブートされ、次のイベントが表示されます。例:
[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.
- ONTAPのブート中に次のエラーが報告されることがあります。例:
WARNING: The battery is experiencing a critical failure:
- Battery full charge capacity is too low
Without a working battery, the system cannot retain data
during a power outage, which can result in data loss.
Power down the system and verify that the battery is
properly installed.
To ignore this failure and boot the system in a mode
where data loss might occur, press 'c' followed by 'Enter'
