As long as you shut down the computer before replacing the controller
and the devices come back online ZFS should import the pool without
A general recommendation would be to use stable device names in your
pool, i.e. the links in /dev/disk/by-id (or by-path, by-vdev, ...).
If your pool is using /dev/sdX as names you could export and re-import
zpool export poolname
zpool import -d /dev/disk/by-id/ pool-name
to switch it over. You may need to rebuild your initrd after this for
the change to become persistent.
