警告メッセージ「NVRAM バッテリー電流が正常値より低い（-50 mA）」
環境
- FAS9000
- FAS9500
- AFF-A700
- AFF-A900
問題
- システムはCHW-66の修正版を実行していますが、依然として同じ症状が見られます。
- FPGAバージョンは、コンソール経由の「
sysconfig -a」コマンド、またはASUPの「SYSCONFIG-A」を調べることで確認できます：
例：
slot 6: NVRAM (NVRAM 10)
Revision: B0
Serial Number: 031945002448
DIMM Size: 16384 MB
Memory Size: 32768 MB
Battery Status: Battery sufficiently charged
Running Firmware: 1.2.0
- EMSログには、「current is below normal (-50 mA)」という警告メッセージの後に、1分以内に「current is normal」というメッセージが表示されます：
例：
node-04 ERROR nvram.battery.current.low.warn: The NVRAM battery current is below normal (-50 mA). To prevent data loss, the system will shut down in 24 hours.
node-04 INFORMATIONAL nvram.battery.current.normal: The NVRAM battery current is normal.
node-04 ALERT callhome.battery.warning: Call home for BATTERY (current low) WARNING.
