Here is an example of the extremely useless wwn or scsi-$LUID in a
zpool. Note that 'nvme' and 'usb' devices DO STILL have their unique
identifier, which is why the nvme device is named correctly:
root@nas-195:~# zpool status
pool: sas195
state: ONLINE
status: Some supported and requested features are not enabled on the pool.
The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(7) for details.

Here is what it should look like - and this is after I applied the config, and
re-imported the zpool and upgraded it:
root@nas-195:~# zpool status
pool: sas195
