Maybe I once had such an ex-AS/400 disk in earlier times which might sit unrecognized in my hard disk drawer. I can’t confirm your claim but I doubt it’s true: Firmware extensions will not get overridden from a reformat, and you can always reformat with 522 Bytes/Sector. I bet it will work again. > And I doubt that there's an orderly shutdown from the panel… That’s exactly what I wanted to express. :-) > I remember being told of only one procedure, but it would not cause > damages/issues of sort. I’ve read about that procedure in an IBM (red)book and it’s „not recommended for regular use“. I would need to look up the source if you want a proof. > In any case we're speaking about something that was meant to be turned on and > never turned off unless some maintenance or a big issue. The OS has highly sophisticated scheduling for automatic start and shutdown, with possible exceptions per weekday and one-time exceptions like holidays. (Type GO POWER into the command line to see the menu.) I guess even one or two decades back, there was reason to save power. > and for a catastrophe where the terminal is not accessible That’s what I mean. The procedure is not meant to be used as a substitute for pwrdwnsys. :wq! PoC
