Can't create volume group with 1.2TB disk

Hi, All,

We have a problem to define a VG with one 1.2TB hdisk which was built by
hardware RAID5 with 9 disks (shown as hdisk5 in AIX). I used command "mkvg
-s 1024 -t 2 -y testvg hdisk5" to create the testvg, so it should be
possible to define a Physical Volume with 1024*2*1016MB = 2.xTB.

But we get the following error message:

0516-024 mkvg: Unable to open physical volume.
        Either PV was not configured or could not be opened. Run
        diagnostics.
0516-862 mkvg: Unable to create volume group.
0516-1254 mkvg: Changing the PVID in the ODM.
Method error (/etc/methods/chgdisk):
        0514-047 Cannot access a device.

0516-024 mkvg: Unable to open physical volume.
        Either PV was not configured or could not be opened. Run
        diagnostics.
0516-862 mkvg: Unable to create volume group.
0516-304 mkvg: Unable to find device id in the Device
        Configuration Database.
0516-324 mkvg: Unable to find PV identifier for physical volume.
        The Device Configuration Database is inconsistent for physical
        volumes.

Any idea why this happens? We are using AIX5.1 .
