I can pull either drive out of the server chassis and install/boot 13.10 server on the remaining drive no problem. As soon as I shut the machine down and re-insert the second drive (whichever one that might be), the system ceases to boot; i.e. I don't get a console and the machine isn't pingable. There's nothing in the BIOS which refers to the disk configuration; I've looked a couple of times already. The HBA is actually made by LSI and has it's own BIOS you can access. This BIOS doesn't have any configurable options that I can find. </blockquote> Hallo Try to post your problem in the channel #ubuntu-server on freenode </body> </html>
