RAID 1 shows up fine in WHS 2011, two separate HDs in Linux?

[jaydee]

I have an HP Proliant N40L that is running as my home server using WHS 2011. I'm tinkering around converting it to Linux Mint Debian Edition (WHS and Linux on two separate HDs, all my data in RAID 1 on two separate drives).

The problem I am seeing, is the two hard drives in RAID 1 (setup in the BIOS) show up fine in WHS 2011 as one logical drive. When I boot into Linux, the two hard drives appear separately with the same data.

I've done a little bit of research and I've found that the RAID controller in my system is embedded into the SATA controller and known as "fake RAID"? http://www.gladdy.co.uk/blog/2012/08/31/building-your-nas-with-a-hp-microserver-n40l Is this what is causing my problem? Is there a way to fix it?

It's not readily apparent to me how to apply those steps to my situation. That thread/solution is to create RAID on a boot drive. I installed the OS on a single drive (its running fine) and am trying to recognize an existing RAID 1 on two other physical data drives in the system.

Also, I'm running LMDE, which is base Debian with a Mint front-end. That thread references "normal" Mint which is Ubuntu-based, which is a little different.

Ubuntu is Debian-based. Many of the steps will be similar.

I do see where the problem might arise though, installing it on an existing system/partition. I'll dig a little more. If I recall, you might have to live install it possibly, but it's been a long time since I've had to deal with such things (raid that doesn't work out of the box).
