Two disk controller in one DiskPool

Hi all,

We are trying to add more disks in our diskpool, so we bought a kit with Baia disk and controller, we setup it in hardware and it´s appear ok, but when I´m try to add it in Disk Management (windows) it shows me that will convert Basic disk in Dynamic disk.

I´m afraid to lost data with this procedure, it´s possible?

Is there a documentation explaining about how to do it?

Thanks.
