Answer

WARNING

The following activity is not recommended, since it can cause significant issues in the storage system if a hardware problem is present.

Disable shutdown only when necessary to complete other recovery or update procedures and ensure it is re-enabled when completed.
Using Bootarg Environment Variables at LOADER
  1. This option is available in ONTAP 9.8 and later.
  2. Reach the LOADER prompt.
  3. To prevent shutdown under all conditions, set the following variable:

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. Complete troubleshooting to correct the issue which would generate the automatic ONTAP shutdown from environmental conditions.
  2. When troubleshooting is complete, you must enable automatic shutdown protection.  Failing to do so may cause catastrophic future results.
  3. Reach the LOADER prompt.
  4. Remove the following variable to re-enable automatic shutdown protection:

LOADER-A> unsetenv bootarg.init.env_shutdown_override

LOADER-A> saveenv

  1. Boot the controller and perform a giveback.

LOADER-A> bye

Using ONTAP Command Line

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