Symptoms

# zpool import 16360934784915433368
cannot import '16360934784915433368': a pool with that name is already created/imported,
and no additional pools with that name were found

We have a zpool as

pool: origpool
id: 1911114640801228349
state: ONLINE
scan: scrub repaired 0 in 1s with 0 errors on Tue Feb 22 19:42:39 2022
config:

NAME STATE READ WRITE CKSUM
origpool ONLINE 0 0 0
c0t5000CCA0708BCFF4d0 ONLINE 0 0 0
errors: No known data errors

There is also a cloned copy of this zpool on c0t5000CCA0708BD318d0, but this will not show with "zpool import" command. But zdb will show

# zdb -l /dev/rdsk/c0t5000CCA0708BD318d0s0

Note that both the zpools has the same pool_guid

Changes

 A new feature was added in Solaris 11.4

zpool reguid pool

Change the guid of a specified pool. The new guid will be generated
automatically. The command will fail if the pool or any of its
vdevs is not in state HEALTHY or if there are any outstanding FMA
faults.
