Here are my notes from downgrading from P20 to P19 on a supermicro box.
modify as needed to go from P19 to P18.

downgrade to P19. P20 has serious bugs.
boot into UFI shell
get to usb
        fs1:
get to fw dir
        cd 9211_8i.p19
erase newer fw
        sas2flash.efi -o -e 6
load new fw and bios
        sas2flash.efi -o -l 2118.log -f 2118it.bin -b mptsas2.rom
