<div>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.<br />
<br />
To use the names in /var/run/disk/by-id,<br />
$ sudo zpool export tank<br />
$ sudo zpool import -d /var/run/disk/by-id tank <new_device_name><br />
<br />
To use the names in /var/run/disk/by-serial,<br />
$ sudo zpool export tank<br />
$ sudo zpool import -d /var/run/disk/by-serial tank <new_device_name><br />
<br />
To use the names in /var/run/disk/by-path,<br />
$ sudo zpool export tank<br />
$ sudo zpool import -d /var/run/disk/by-path tank <new_device_name><br />
<br />
To use the less safe (because they vary) BSD disk names in /dev,<br />
$ sudo zpool export tank<br />
$ sudo zpool import -d /dev tank<br />
<br />
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,<br />
