So what I did is

# zpool attach rpool 9083243097870587132 
/devices/pci at 0,0/pci103c,807c at 14/storage at d/disk at 0,0:q

# bootadm install-bootloader -P rpool

# zpool detach rpool c6t0d0s0


# zpool status
   pool: rpool
  state: ONLINE
   scan: resilvered 30,5M in 0 days 00:00:01 with 0 errors on Mon Jun 27

   pool: szpool

   scan: none requested
config:

         szpool         ONLINE       0     0     0
           /dev/lofi/1  ONLINE       0     0     0
