Hi,
I have a Asus M2NPV-VM motherboard which supports hardware RAID. I have installed Fedora 7 on the first SATA hard disk (sda). Now I have added two more identical SATA hard disks and configured them as mirrored RAID in BIOS.
In the OS I can still see them as sdb and sdc and not as one single disk. My vendor tells me that I have to reinstall the OS for it to detect the RAID disk. I do not want to reinstall as I have done lot of customization.
Can any one please help me in configuring the RAID without reinstalling the OS. Any pointers would also be welcome.
Thanks and regards.

Is it really raid or is it fakeraid? Many of these mother-boards which come with inbuilt raid are not really raid. They are fake raid which require support from a software driver. In such a case disable the raid in the BIOS and use mdadm to do software raid which is anyday better than fakeraid.
Also., what RAID card is this? A lspci should tell you.

I think it is a fakeraid as I got from Google search yesterday. Can you please explain why a software raid is better than fakeraid and/or what is fakeraid or some links for me to read. I could not get much from my search yesterday, but I was mainly searching for hardware raid configuration.

This is what lspci tells me:
00:0e.0 RAID bus controller: nVidia Corporation MCP51 Serial ATA Controller (rev a1) 00:0f.0 RAID bus controller: nVidia Corporation MCP51 Serial ATA Controller (rev a1)
Thanks and regards.
