I used part of some old notes from yourself at 
https://wiki.openindiana.org/oi/How+to+migrate+the+root+pool and 
manually updated the Solaris partition table to look more like the 
original one and also the partition tables on OmniOS systems I have 
here.  However, the partition table type is of type Solaris ('SMI') 
whereas the partition table type of the peer existing disk is 'EFI'. 
After configuring the Solaris partitions, I executed 'label' at which 
time it asked me if I wanted to use a SMI or EFI label.  This 
happened:

partition> label
[0] SMI Label
[1] EFI Label
Specify Label type[0]: 1
Warning: This disk has an SMI label. Changing to EFI label will erase 
all
current partitions.
Continue? n
partition> label
[0] SMI Label
[1] EFI Label
Specify Label type[0]:
Ready to label disk, continue? y

So I am using the SMI label type rather than the EFI label type.

The above does not occur in your Wiki article so it must be a more 
modern 'fdisk' feature.

It is my understanding that the partitioning/format of the existing 
disk came from a from-scratch OpenIndiana Hipster install done perhaps 
a year ago.  If this EFI partitioning is what is done now, the Wiki 
does not seem to reflect it.

The new disk is being resilvered into the root pool now.

If I have made a mistake, I can remove the device from the pool and 
try again.

FYI: It appears that the Wiki server must be down again.
