I would think you should be able to do it, but I've only ever heard folks discuss even numbers when discussing RAID-DP groups.

My FAS2050 has 2 RAID groups of 13 and has done so for the last couple of years. I believe that&nbsp; Netapp will recommend that you leave RAID groups size at default though.</P></BODY></HTML> Thu, 17 Feb 2011 18:53:09 GMT https://community.netapp.com/t5/ONTAP-Hardware/Odd-Numbered-RAID-DP-Group/m-p/44650#M3101 jb2cool01 2011-02-17T18:53:09Z
