That is too big for 32 bit labels, which means that you cannot use either 
fdisk or disklabel to manipulate it (and get access to all of its space).

It also most likely means that you cannot use sysinst (or not the regular
way) as sysinst's GPT support is poor.

Completely destroy the label sectors of the disk (with dd from /dev/zero,
which is in no way a "low level format", but never mind) and re-init it
using "gpt create", and avoid using fdisk or disklabel at all (if you
really need to, fdisk to just display the protective MBR is safe, but
nothing which edits the MBR)

Don't use disklabel, or mbrlabel, or any variant of any of those.
