Which are connected to the onboard raid controller or the megaraid controller?
Are the 2 disks on the internal channel and if so on which controller?

Ahh, if you have more then one controller this mixup is quite common. You 
probably want to boot from the 2 disks in the server but somehow the 
bootload probably got loaded onto the the wrong set of drives.

That would be expected since the bootdisk has almost no drivers at all and 
the disk driver you need probably isn't included.

The bios and linux fighting over which disk is the bootdisk is always 
somewhat of a mess.

If you boot the linux installer cd and boot it with "linux rescue" you can 
get into the rescue mode and see what modules are loaded and using dmesg 
you can look which disk becomes sda and which sdb.


It might just be your lucky day, if you only knew.
