Creating Dynamic disks on Netfinity

I have a Netfinity xSeries 220 Type 8646-31X.
I want to convert the Disk0 from a basic to a dynamic disk.
I’ve done this with W/2000 before but the Netfinity doesn’t like the way W/2000 disk management handles the Netfinitysp volume. Where can I look to find directions for the process I need? As step by step as possible please.
