Technical Tip: Factory reset with an enabled VDOM

When a VDOM is enabled, it is not possible to proceed a factory reset  without going to global mode without facing the below issue:

Fortigate # execute factoryreset
8497: Unknown action 0
Command fail. Return code -1

With keyboard help shortcut (?) all available commands are listed but execute is not there.

FGT # ?
config     Configure object.
get        Get dynamic and system information.
show       Show configuration.
exit       Exit the CLI.

Go to global mode and run the command 'execute factoryreset'

Below is the sample output:

Fortigate # config global

Fortigate (global) # execute factoryreset
This operation will reset the system to factory default!
Do you want to continue? (y/n)y

System is resetting to factory default...

The system is going down NOW !!

Fortigate (global) #
Please stand by while rebooting the system.
Restarting system.

System is starting...
Serial number is FGVMxxxxxxx
