Hi again,
that got slightly further, but still no dice:
root@openindiana-01:/mnt# zpool import -d /dev/lofi -FVX ZP-8T-RZ1-01
root@openindiana-01:/mnt# zpool list
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
ZP-8T-RZ1-01 - - - - - FAULTED -
rpool 15.9G 2.17G 13.7G 13% 1.00x ONLINE -
root@openindiana-01:/mnt# zpool status
pool: ZP-8T-RZ1-01
state: FAULTED
status: One or more devices could not be used because the label is missing
or invalid. There are insufficient replicas for the pool to continue
functioning.
action: Destroy and re-create the pool from
a backup source.

cannot scrub 'ZP-8T-RZ1-01': pool is currently unavailable
Thanks for your tenacity Stefan.
