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
- This option is available in ONTAP 9.8 and later.
- Reach the LOADER prompt.
- 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
- Complete troubleshooting to correct the issue which would generate the automatic ONTAP shutdown from environmental conditions.
- When troubleshooting is complete, you must enable automatic shutdown protection. Failing to do so may cause catastrophic future results.
- Reach the LOADER prompt.
- Remove the following variable to re-enable automatic shutdown protection:
LOADER-A> unsetenv bootarg.init.env_shutdown_override
LOADER-A> saveenv
- Boot the controller and perform a giveback.
