Hmm, are you sure that your RAID has been recognized correctly? In
case you don't have another RAID-set or a standalone disk/CD Rom, your
RAID-set should be accessible as /dev/sda. So what's behind /dev/sda
in your case?
No, I'm not. But I cannot access /dev/sda.
From a terminal (LiveCD booted):
# fdisk /dev/sda
Unable to open /dev/sda
Can you provide the SCSI/RAID related dmesg output from the live-CD?
Do you have a SCSI-CD Rom or an IDE/(S)ATA one?
I may access /dev/sdb though (that's why the I installed Gentoo on sdb).
So, to summarize: Check that your RAID set has been recognized
properly before installing with the live-CD. Investigate why you only
have one SCSI device in contrast to two on the live CD (missing SCSI
CD-ROM support?).
I'm not sure how to do that. I'm not even sure if /dev/sdb is the actual
RAID or just one of the drives? But when I come to think about it...
when I try to boot the system, the Dell server actually boots from the
logical drive and it do find the kernel, hence /dev/sdb is infact the
RAID, right?
I also removed one of the drives, tried to boot (it finds the kernel),
then I removed the other drive and rebooted and it still finds the kernel).
Ok, I would also assume that your mirroring RAID-set is working then ;)

I can't see how this could make any difference when I can't even mount
the root device? Anyway, I'm desperate and will try this as soon as I can.
No, those utilities won't be necessary as you're running a hardware
RAID, their supposed to create/manage software RAIDs.
Have you ever tried to use /dev/sda in your grub config and fstab (as
your kernel recognizes an sda SCSI disk) ?
