As decribed; this is a problem because the webtool won't have the required information; and as most HP's have a CCISS option and most Dell's have a Megaraid option this could prove problematic. The last common RAID card is the AACRAID so that should be verified as well. As for SX8 we'll have to see, I have one available unfortunately the system won't install :(
hardware.py corrects this for us, up2date version added as package requirement
