2TB size limit on PERC4/ei?

I have a PE 6800 with a PERC 4/ei controller. IT has 10 300GB physical 
drives.  In the PERC BIOS setup it shows each drive as 286080MB.  In a 
raid 5 it should be 286 x 9 = 2.574TB.  But when I select all 10 drives 
into a RAID 5 it shows size as 2097144MB and LD 0.  Then when I accept 
that, it pops up LD 1 with size 477576MB.  Am I hitting a 2TB limit?  
Any way to overcome this?  I'd like to have 1 logical drive of 2.574TB, 
and not a logical drive of 2TB and a second logical drive of 477GB.
