How does a controller behave after an electrical failure while in "system power off" state

Hello,

I did not find an answer neither in doc nor in the forums.

My question is quite simple. What does happen when a controller is in such a situation ?

- The controller has been halted with an "halt -f" command

- From the SP, the following command has been executed: "system power off", so the motherboard has no more power supply, but SP is still active.

- There is an electrical failure, so all PS supply is interrupted, including to shelves and SP module.

What does happen when power comes back ?

- Is there an auto boot ?

- Or does the SP interrupts the boot to be in the exact same state than before the failure ?

I believe, it will do an autoboot as usual and as soon as disks are back, but I need to be sure (and my customer too).

Thank you for your answers.
