Your drive is claiming to be 4kB/sector, which would increase the max
drive size up to 16TB, if the 12 byte SCSI command limitation applies
(which is just my speculation).
So this would indicate a work-a-round for the 2TB limit is to use a
drive which reports a real 4k sector size.

However, it's not clear this was the USB drive rather than a bare 3 TB SATA
drive. I was battling several things and a few years later it's not as clear
as it seemed when I wrote it. I vividly recall I had a lot of trouble getting
it to work properly, and considered just giving the drive to a friend to use on
his Mac.
But yes, it can be made to work. I use it to save incrementals from my backup
server.
The following is w/ the drive imported to my 151a8 internet access host.

Which looks wrong, so I'm not sure what's going on. I had loads of fun w/ the
sector alignment. You should look at the ZFS pages. Klimov and I tried to
document some of this stuff. George Wilson's writeup proved quite important,
so make sure you read that also.

I did this on the N40L which is powered down at the moment, but there is
probably more info on that. The notes quoted above are from my log book.

[2nd attempt - first vanished into a black hole]
I had a quick look through scsa2usb.c (not that it's an area
I know),
and I can only see it using Group 5 (12 byte) SCSI commands.
This will
limit the addressing to 2^32 blocks, which is 2TB for a
512byte/sector disk.
So if I'm right, this is a limitation of USB-connected
drives on Illumos.
