mpt problem on a Supermicro motherboard (FreeBSD 9.2 amd64)

[Victor Sudakov]

Colleagues,

I have several Supermicro-based servers with the mpt RAID adapter:

# mptutil show adapter
mpt0 Adapter:
       Board Name: UNUSED
   Board Assembly:
        Chip Name: C1068E
    Chip Revision: UNUSED
      RAID Levels: none
#

The problem is, I cannot configure any RAIDs (please see output
below) from FreeBSD. If I configure volumes from BIOS setup, FreeBSD
still sees them as separate physical discs.  What am I doing wrong? 

I cannot use gmirror with these servers because a) if no MPT RAID is
configured in BIOS setup, it cannot boot from HDD and b) if an MPT
RAID *is* configured in BIOS setup, it occupies the last sector and
prevents GEOM from working with these drives. 

Any help please? (or redirect me to a more appropriate maillist).

# mptutil clear
Are you sure you wish to clear the configuration on mpt0? [y/N] y
mpt0: Configuration cleared
# mptutil show volumes
mpt0 Volumes:
  Id     Size    Level   Stripe State Write-Cache  Name
# mptutil show drives
