The issue that is not readily apparent is that the ZFS BE is not mounted automatically (canmount=noauto) so you have to mount it specifically during a recovery boot: # zpool import -R /a rpool # zfs mount root/ROOTcmroot I've documented this process here: http://www.solarisinternals.com/wiki/index.php/ZFS_Troubleshooting_Guide#Recover_from_Lost_Root_Password_or_Similar_Problem Good topic...Thanks!
