为什么 "raid.timeout" 选项无法避免环境关闭？

ONTAP 9

• 错误146654- 对于触发关闭的NV电池事件、ONTAP 会忽略"raid.timeout"选项
• 环境 NVRAM 电池已满电量容量错误不受 raid.timeout 选项控制。示例：

::>storage raid-options show -node * -name raid.timeout*
Node    Option                      Value     Constraint
-------- ---------------------------------------------- ------------ ----------
node_name-1
     raid.timeout                  60      only_one
node_name-2
     raid.timeout                  60      only_one
2 entries were displayed.

但是：

[node_name: env_mgr: nvram.battery.fcc.low:error]: The NVRAM battery full-charge capacity is low (48 %). To prevent data loss, the system will shut down in 24 hours.
