問題

  • 次のバッテリー アラートはイベントログに記録されます。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!
  • 何も操作が行われない場合、ノードは24時間ごとに再起動し、以下のイベントが確認されます。 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の起動中に、次のエラーが報告される場合があります。 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'

追加情報

プロアクティブな修復
  • コントローラで記載されている問題が発生していない場合は、BMCファームウェアを19.3以降にアップグレードして問題の発生を防止してください
  • ONTAPのService Processor(SP)またはBaseboard Management Controller(BMC)を更新する手順でいずれかのアップグレードオプションを選択してください
  • BMCファームウェアのアップグレードの一環として、NVMEMバッテリファームウェアがバージョンB1に更新されます
BMC ファームウェアのアップグレード後、バッテリファームウェアがバージョン B1 へのアップデートに失敗する
