- ONTAPのブート中に次のエラーが報告される場合があります：
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'
