The main point is you *cannot* have an EFI label. That means that you
must have a normal fdisk Solaris partition, and a slice that is the same
size as the other disk's. To do this, do:
# zpool status rpool
...
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c5t0d0s0 ONLINE 0 0 0
...
# format -e c5t0d0
...
format> fdisk
...

6. Cancel (exit without updating disk configuration)
Enter Selection: 6

SELECT ONE OF THE FOLLOWING:
1. Create a partition
2. Specify the active partition
3. Delete a partition
...
Enter Selection: 3
Specify the partition number to delete (or enter 0 to exit): 1
Are you sure you want to delete...: y

Partition 1 has been deleted.

Enter Selection: 1
Select the partition type to create:
1=SOLARIS2 2=UNIX 3=PCIXOS 4=Other
5=DOS12 6=DOS16 7=DOSEXT 8=DOSBIG
9=DOS16LBA A=x86 Boot B=Diagnostic C=FAT32
D=FAT32LBA E=DOSEXTLBA F=EFI 0=Exit? 1
Specify the percentage of disk to use for this partition
(or type "c" to specify the size in cylinders). 100Should this become the active
partition? If yes, it will be activated
each time the computer is reset or turned on.
Please type "y" or "n". y

Then make the partition table match the partition table for the original
disk we printed up above. and then do:

# zpool attach rpool c5t0d0s0 c6t0d0s0
And everything should work.
