No, the disk devices presented is just emulating SCSI.  The OS has no
intimate knowledge about the RAID's internal configuration.  It will
look this way even on a 3ware escalade RAID controller, which is IDE!
We have chosen to unify the interface to the disklike RAIDsets to be
like SCSI, as it simplifies management.  However this also means that
we are lying somewhat.  It is not SCSI at all, let alone SCSI2, it is
RAID.

I am not sure what you are saying here.  fdisk is irrelevant, nothing
really cares about fdisk, but the BIOS (a slight lie, but it suffices
to say that for the point of this discussion).  What matter is what
you have configured your RAID to be.  I guess you have configured it
to be 17767890 sectors, and you seem to be using it all.  Or do I
misunderstand what you are asking about?
