Yeh, I know for a fact you cannot setup Hdds for an as/400 unless with the ibm factory tool. ( saw people using AS for a lot of years professionally discuss this )
You had an as400, you had to buy the spares hdds sold by ibm and ibm only

About the panel ... let me see...

Press 1 time "arrow up" to get 02 on the display
Press "insert" > panel will show "02 BN"
Press 4 times "arrow up" so that it changes to "02 BM"
Press 2 times the white power on button, to start the shutdown/poweroff phase

Yap. See here for details (and further reading).

Do you have experience with this? Because, you certainly can format a disk in the „BIOS“ (Dedicated Service Tools) of a machine. And I suppose that doing this is doing the right thing.

I know no safe way to initiate a proper shutdown from the panel. Do you have more information on that?

I guess it’s included, eventhough not mentioned in the text. And I fully agree, Console is important to have.

:wq! PoC
