It should not matter if the controller numbers have changed. There are a few scenarios:
1. If the pool is active, and the underlying driver supports devids, then ZFS will still be able to open the correct devices. If the underlying driver doesn't support devids, or if the devids have also changed (both extremely unlikely), then the pool will come up faulted. 2. If the pool is exported, then 'zpool import' is able to recover arbitrary reconfigurations - devids/paths/whatever. It reconstructs the configuration based solely on the on-disk data it discovers while walking disks in the system.
