警告

不建议执行以下活动，因为如果存在硬件问题，则可能会导致存储系统中出现重大问题。

仅在需要完成其他恢复或更新过程时禁用关机，并确保在完成后重新启用。
在 LOADER 中使用 Bootarg 环境变量
  1. 此选项在 ONTAP 9.8 及更高版本中可用。
  2. 达到LOADER 提示。
  3. 要防止在任何情况下关机，请设置以下变量：

LOADER-A>setenv bootarg.init.env_shutdown_override true

LOADER-A>saveenv

LOADER-A>printenv bootarg.init.env_shutdown_override

Variable Name     Value
-------------------- --------------------------------------------------
bootarg.init.env_shutdown_override true

  1. 完成故障排除，纠正因环境条件导致 ONTAP 自动关机的问题。
  2. 故障排除完成后，必须启用自动关机保护。  否则可能会导致灾难性的后果。
  3. 到达LOADER 提示符。
  4. 删除以下变量以重新启用自动关机保护：

LOADER-A>unsetenv bootarg.init.env_shutdown_override

LOADER-A>saveenv

  1. 启动控制器并执行 giveback。

LOADER-A>bye

使用 ONTAP 命令行

Please contact NetApp Technical Support or log into the NetApp Support Site to create a case. Reference this article for assistance with the solution. 

  • The solution requires Diagnostic-level recovery. 
  • The use of Diagnostic commands and recovery steps is potentially disruptive and should only be used with guidance from NetApp Support.
