>Description:
1:
From HP Proliant ML115G1, remove original 80GB HDD, replace 4x 1.5TB SATA HDD.
Build on-board RAID0+1, it has recognized 1 ATA RAID drive, 2.72TB.
But FreeBSD's ar(4) driver recognized only 0.7TB ar0.

2:
Then, I have try GEOM framework with FixIt CD-ROM.
But, not only "gpt" also "gpart" recognized only 0.7TB too.
>How-To-Repeat:

>Fix:
ar(4) driver should be 64bit clean, to proper recognize over 2TB HDD.

State-Changed-Why:  
I highly doubt that this will see work soon, I think one could better 
try to use gmirror or ZFS.
