p2000G3 - remove disks from RAID

Hello everyone.

Here is what I have:

- p2000G3 FC dual controller

- 6 HDD x 300 GB RAID 10

6 HDD x 600 GB added.

Expanding the existing RAID10 gives me a lot of overhead and very little free space.

Added 2 RAID0 of 1200 gave me just 600 GB free.

Is there a way to remove them from RAID and recreate a new vdisk instead of adding to the existing one?

Thank you.
