Solaris zone is powerfull virtualization for unix platform. There many many flexibilities in use hardware resource. For example, you want to assign a dedicated zfs dataset to a zone.
Solaris zone configuration utility (zonecfg) has a zone property to accomodate this requirement. Enter to zone configuration and specify the dataset name so the dataset will be active in the zone when it running.
root@global:~# /usr/sbin/zpool list
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
rpool 49.5G 25.9G 23.6G 52% 1.00x ONLINE -
zonepool 12.9G 942M 12.0G 7% 1.00x ONLINE -
root@global:~# zfs create zonepool/oradb
root@global:~# /usr/sbin/zonecfg -z zonedb
zonecfg:zonedb> add dataset
zonecfg:zonedb:dataset> set name=zonepool/oradb
zonecfg:zonedb:dataset> end
zonecfg:zonedb> verify
zonecfg:zonedb> commit
zonecfg:zonedb> exit
Boot the zone zonedb and check the dataset oradb :
root@global:~# /usr/sbin/zoneadm -z zonedb boot -- -m verbose
root@zonedb:~# zfs list

Dataset 'oradb' known as pool in zonedb zone as bellow :
root@zonedb:~# zpool list
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
oradb 12.9G 941M 12.0G 7% 1.00x ONLINE -
rpool 12.9G 941M 12.0G 7% 1.00x ONLINE -
Check the mounted devices, the oradb dataset as known as pool in zonedb. At the mounted device it's automatically mounted and include it in 'df' output :
root@zonedb:~# df -h

Thats all, only 2 step required to assign dataset to your solaris zone.
