由于NVRAM电池电量低、控制器关闭

• 新控制器刚刚安装完毕
• 启动ONTAP时、命令行界面上将显示以下消息

WARNING:  The battery is unfit to retain data during a power
      outage.  This is likely because the battery is
      discharged but could be due to other temporary
      conditions.
      When the battery is ready, the boot process will
      complete and services will be engaged.
      To override this delay, press 'c' followed by 'Enter'

• 系统将忽略此警告、并强制ONTAP启动

CAUTION: Using this appliance without NVRAM
     battery backup coupled with a power
     failure condition CAN CAUSE DATA LOSS.

Are you sure you want to continue (y or n)? y

Proceeding without NVRAM battery backup.
