You mean 2TiB? Partitions greater than 2GiB (but less than 2TiB) 
should "just work".

If that's the case, you need to use a real partition table as the 
traditional MSDOS partitioning scheme is limited to 2TiB partitions or 
devices (it can't address disk locations beyond this point).

The GPT partition format is widely used on ia64 and does not have this 
limitation. It's supported by parted and most distribution installers 
(even for non-Itanium systems).
