Changing the device names on an existing pool can be done by simply exporting the pool and re-importing it with the -d option to specify which new names should be used.
To use the names in /var/run/disk/by-id,
$ sudo zpool export tank $ sudo zpool import -d /var/run/disk/by-id tank <new_device_name>
To use the names in /var/run/disk/by-serial,
$ sudo zpool export tank $ sudo zpool import -d /var/run/disk/by-serial tank <new_device_name>
To use the names in /var/run/disk/by-path,
$ sudo zpool export tank $ sudo zpool import -d /var/run/disk/by-path tank <new_device_name>
To use the less safe (because they vary) BSD disk names in /dev,
$ sudo zpool export tank $ sudo zpool import -d /dev tank
Even if you are using invariant paths (by-id, by-serial, or by-path), you can reveal the "normal" BSD disk names at any time,
$ zpool status -L tank
