I replaced my OS disk and now only the rpool was visible using zpool status. In order to see other existing pools run zpool import without options:
# zpool import
pool: dawpool
id: 8233866255479348343
state: ONLINE
status: The pool was last accessed by another system.
action: The pool can be imported using its name or numeric identifier and
the '-f' flag.

config:
dawpool ONLINE
raidz1 ONLINE
c8t0d0 ONLINE
c8t1d0 ONLINE
c8t2d0 ONLINE
spares
c8t3d0
There it is again my raidz pool ready to be imported
