Successfully updated my 8 disk Asrock C70M1-system but not without entering a valid serial/mac-pair, otherwise no IP. Btrfs was available and after making the conf-file change, also SHR was available. (see next post of Polanskiman)
Accidentally my HP Proliant N54L updated itself from 8 to 9. It was still active but lost its IP. After restarting it worked again. Marvelous! I am so happy with Jun's loader!
