Newbie for solaris 10 and zfs

I have a Sun T2000 machines and require to reinstall the OS (Solaris 10 05/09).
During installation, it prompts me about using UFS/ZFS and I'd chosen ZFS and choose to separate /root and /var.

After installation, it displays the following:

Code:

It seems that the /root shares the space with /var
How can I separate the /var?
Do I need to backup and create a new pool?

Thanks.

/var is a separate filesystem from / in your setup.
You can set a quota on /var if you want it not to affect the remaining filesystems.
