Solaris 10 non global zone queries

Hi,

I have created a non global zone in a Solaris 10 M9000 domain. I have added the zfs dataset. I wanted to have the mount point of the dataset in the non-global zone as /u01.

I tried to use "zfs set pointmount=u01 rpool/myzone/u01" but the system refused to change with the following:

cannot set property for 'rpool/myzone/u01': 'mountpoint' cannot be set on dataset in a non-global zone

When I issue the zfs get command, the result shows below:

# zfs get mountpoint rpool/myzone/u01

NAME                PROPERTY    VALUE                SOURCE

rpool/myzone/u01  mountpoint  /rpool/myzone/u01  default  <--- don't understand why it is default instead of local
