Have a Dell Poweredge 2800 server with 3 x 72Gb UW scsi hard drives built around an on-board RAID5 array running SBS2003. Recently, on re-booting, it started produced a message along the lines of 'RAID degraded - press Alt-something to enter RAID config or any other key to continue'. Pressing any other key allowed it to boot & run ok. Today however, it refuses to boot. Looking for inspiration on whether the issue most likely lies with the drives or the RAID controller and, in each case, possible remedies. I understand a 3-disk RAID5 will run ok on 2 disks so one theory is that one disk failed some weeks back, hence the 'degraded' error described above and another disk failed today, leaving only one good disk. If this is the case, I've taken advice to effect that I'm screwed as RAID5 needs 2 out of 3 drives to function. Another possibility, and I can't rule this out, is that somebody took it upon themselves to go into the RAID config and mess with some settings.... in which case, does anyone know what the correct settings should be so I can check them? Final possibility is that the RAID controller is wrecked, in which case are we talking new motherboard? In this scenario, as a new board is likely to be expensive and may take some time to get hold of, what are chances of sticking all 3 drives in a new server & getting them to work?
