How to use Norton Ghost 10 on a Raid configuration?

Hi,

I just installed a new Dimension 510 with a 2nd drive in a Raid configuration.
Installed on the machine is a Ghost 10.0 software. In the explaination of the machine is mentioned that these drives mirror eachother, so if one fails, there is still the 2nd one to go on working.
The trouble is:
There is no explaination how to configure Ghost to perform that task.
Not even the Ghost manual mentions that option...

Anybody got an idea?

Thanks!
