64-bit LBA addressing?

[danci at agenda.si]

Hello,

I have a new storage device where I intended to use a huge logical volume 
(~ 4TB) using an aic79xx card. Unfortunately, if I make a LV that big, 
linux detects that as a disk with 0 cylinders.

After asking the manufacturer (Infortrend), they suggested that the HBA 
hardware AND driver needs to support 64-bit LBA addressing and to their 
knowledge, only LSI HBA's do that.

So, do aic79xx card and driver support 64-bit LBA addressing? 

If not - is it a hardware issue, a driver issue or both?

 Thanks, Danilo
