Can't mount second disk under OpenSolaris

[UncleBensSauce]

Hi - I have a machine with a standard 2008.11 build on and for some reason cannot get it to mount an additional HDD. I'm currently running on c4t0d0 (see below) and want to add c4t1d0 as a second hdd.

tom@opensolaris:~# format
Searching for disks...done


AVAILABLE DISK SELECTIONS:
0. c4t0d0 <DEFAULT cyl 48638 alt 2 hd 255 sec 63>
/pci@0,0/pci1019,1b51@7/disk@0,0
1. c4t1d0 <DEFAULT cyl 19926 alt 2 hd 255 sec 63>
/pci@0,0/pci1019,1b51@7/disk@1,0
Specify disk (enter its number): ^C
tom@opensolaris:~# mount /dev/dsk/c4t1d0s0 /mnt
mount: I/O error
mount: Cannot mount /dev/dsk/c4t1d0s0

Ok - it doesn;'t work, but oh yeah zfs is here so I should:

tom@opensolaris:~# zpool status -v
pool: rpool
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on older software versions.
scrub: none requested
config:

NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c4t0d0s0 ONLINE 0 0 0

errors: No known data errors

All good - I can see my current drive, so i need to...

tom@opensolaris:~# zpool add rpool c4t1d0s0
cannot open '/dev/dsk/c4t1d0s0': I/O error
tom@opensolaris:~# zpool add rpool c4t1d0
cannot label 'c4t1d0': EFI labeled devices are not supported on root pools.

EFI?!...

Now I'm stumped, I know this disk does not have an EFI label because:

format> label
Ready to label disk, continue? yes

format>

Any ideas?

Can you do it with -f?

i.e.

zpool add -f rpool c4t1d0
