IBM ‐ Factory Reset S822L - kth5/archpower GitHub Wiki

This will perform a full factory reset of a IBM S822L (potentially other machines) using only physical pull-out control panel. Coincidentally, this also removes all HMC, networking and password configurations and resets them to their respective defaults. We log it here because it was a lot of work to find this, it's immensely useful when you get a used one second hand and most of the time aren't provided with all credentials.
