The newly attaching disk (slice in this case, because it is an
rpool) must have the same number of blocks, or more.
Even though you may have two disks with the same vendor
label, they may have a different number of available blocks.
prtvtoc provides this info relatively easily as the "sector
count" column. Compare:
prtvtoc /dev/rdsk/c0t0d0s0
prtvtoc /dev/rdsk/c0t8d0s0 (!!)
As Cyril notes, and the ZFS Administration Guide says,
you must use a slice for the rpool, not a whole disk.
