I've noticed the system freezes unexpectedly in the EFI shell. Do you think this is hardware?
There is an adaptec 3405 Raid card. It reports 3 drives optimal and no errors. Could this card be giving an issue perhaps?

The LIVE CD is v big to download... any other suggestions?
You will need some CD/DVD to perform a rescue. So I think "arnold's" comment is crucial going forward.
Do you still have the cd/DVD you used to install the system? You can use that.
The efi shell might mean there is no menu for what/how to boot the system.

Say, I've booted with a boot CD and can't see the SCSI Raid hard disk even though the RAID shows array optimal.
Should I run the Adaptec Array utility and Verify the disk?

I believe the issue is around the raid drive not being detected by BIOS and the EFI shell may need a command or two run in it?
ASKER
The device mapping shows only the DVD drive. This is most strange as the Adaptec Raid reports raid is optimal

RAID card was overheating - blew it cool with air blower and all solved.... Tx 4 info
RAID card overheating is decisively a RAID card failure.. although this may be caused by improper cooling within the chassis, blockage of air inlets, or an unusually high ambient temperature.
If you haven't made permanent repairs to the cooling, you may need to.
Blowing off a card once with an air blower sounds like a temporary fix.

Can you use centos liveCD to check the boot loader.
