Unfortunately NetApp dramatically increased the minimum size of the root volume in Ontap 8 and there is no supported way to get around it:

http://now.netapp.com/NOW/knowledge/docs/ontap/rel802/html/ontap/sysadmin/GUID-94356B0F-EB14-43E5-9AEC-8EDDC6AA02AA.html

BTW, it is a bit surprising that the documentation (160 GB) does not match the limit Ontap 8 actually reports (133 GB).
