I want use software raid md/lvm.

Is any way to totally disable this raid and see "raw" sata disks?

I play alot with BIOS , enable SATA, disable raid controller, but nothing happents, i not see the disks.

I had a similar problem with the LSI controller. I've every single disk exported as a JBOD device.

Are you trying to use a filesystem solution like ZFS, which prefers RAW disks? If so, the better long-term approach is to use a dedicated SAS controller (HBA) instead of a RAID controller. I tend to prefer LSI's offerings.
