由于NVRAM电池电量低、两个控制器均关闭

• 刚刚安装了两个新控制器
• 启动ONTAP 时、命令行界面上会显示以下消息

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、并强制启动ONTAP

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.

• 控制器暂停、并显示以下消息

[node-01:monitor.shutdown.emergency:EMERGENCY]: Emergency shutdown: Environmental Reason Shutdown (Battery remain capacity critical)
