DB restore

If I have a 20GB database that is spread accross 10 dbvols but is only 10% utilized can I restore that database onto a server with 5 dbvols totaling 10GB since the 5 dbvols will hold over the 10% of utilization.

3466 C01

Does anyone know the default size of the dbvols and logvols on the 3466 C01? Thanks
