If you add the SUNWzfsg package from a Solaris 10 10/09 release to a system that runs a pre-Solaris 10 6/06 release, which does not have the embedded_su patch, the ZFS Administration application wizards are not fully functional.
If you attempt to run the ZFS Administration application on a system without the embedded_su patch, you will only be able to browse your ZFS configuration. The following error message is displayed:
/usr/lib/embedded_su: not found
Add the embedded_su patch (119574-02) to the system that runs a pre-Solaris 10 6/06 release.
