- 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'
