I have a HP Proliant DL360 g5, and am trying to install archlinux. It has a HP Smart array controller with 6 drives (all green) creating two logical volumes (one volume with 5 RAID6 drives, and the boot volume with one RAID0). I used the ORCA (array configuration tool) to select the smaller volume as the boot volume. I installed archlinux (using pacstrap, and the Installation Guide), and I created a single GPT partition (ext4), installing syslinux and its BIOS bootloader (https://wiki.archlinux.org/index.php/Syslinux#Installation). When I reboot, Proliant says "Non system disk or disk error". I also tried setting the other volume as the "bootable" volume (in case I had chosen the wrong one), but this didn't help.
Is GPT+BIOS+Syslinux a viable booting strategy on this server?
My reading suggests that the server is incapable of EFI/UEFI booting, so I'm pretty sure MBR/BIOS installation is correct.
