Clearing up some things with this. This server is second hand, and almost definitely older than 11 years. There is no software that came with it, as the business that gave it to me only did so because they removed all the data. What I have is just the hardware, and a USB stick I shoved the OS on.
In the BIOS there is a RAID option next to the AHCI, would that work?

There's bound to be some documentation on the Internet.

No, that relates to the onboard SATA controller.
During POST, after the memory test, a message related to the RAID controller should appear onscreen, most likely telling you which key you need to press to enter the RAID setup.

All I've been shown is the screen saying how to get to BIOS and settings.

If the drives are indeed SAS drives, there has to be a controller in there somewhere. Did nothing appear after the main BIOS screen?
Some BIOSes have a setting that specifically allow expansion ROMs. You may need to enable that.

I'll try that when I get back, if that doesn't work I'll try updating the BIOS and seeing if that gives me the option

I could be wrong again... but as far as I know this mother board uses the Intel's Embedded Server RAID technology which is a fake RAID and is built into the BIOS but not a true hardware RAID controller. There is a BIOS configuration setup page but as far as I know no separate BIOS as one would expect with a hardware controller.
The dmraid module does not work with ERST2

You're right about that, it has 6 onboard SATA ports.
But that's just it; they're SATA ports. The OP claims to have SAS disks, which would imply a separate controller.

I believe that it is the same for the SAS drives. Did you read the info on the mother board I posted earlier.

I did. The Intel S5500/S5520 series motherboards have 6 onboard SATA ports and no SAS ports.
You can add a "SAS Entry RAID Module" (page 14), which adds 4 SAS ports. This is actually an LSI SAS1064e controller on a proprietary board. If installed, it should activate additional BIOS options which the OP doesn't seem to have.
So either there's another controller involved, or he has somehow ended up with a SATA-only server and a bunch of SAS disks he can't use.

Considering the previous owner was using SAS drives with no problems, I don't think that's the issue.
The motherboard has a card in one of the slots which connects via cable to another board entirely which is designed to allow SAS drives.

Agreed.

That's what I thought.
Is the "other board" the hotplug backplane (the rear of the drive cage)?

Nothing like that appeared in my BIOS options

I believe that's right. I figured I shouldn't just shove a SATA drive in and mess with it that way, so I haven't tried that yet. It's got six slots for drives to be slid in on those little drawer things, of which i have five drives inserted, none of which show up.
Also, I tried the RAID configuration next to the AHCI just in case and still nothing.

You should try reseating the controller card. Large PCIe cards can get misaligned during transport.
Disconnect the power cord (otherwise there will be standby power to the PCIe slots), and then remove the card and put it back into the slot a few times.

Will do, I'll let you know if it works
