hi.
Thanks for the reply, the 8 bay R510 has 4 internal sata ports but no way of powering them. but luckily enough I have just this minute resolved the issue, with a combination of updating all the R510 firmware and modifying the grub file to add the sata controller, unsure of which of these solved it but its working and have been able to do all updates. The onboard lan ports arnt working but that's fine and expected.
