Hi All,

I have a Dell R710 that has 6x1TB in a RAID-5 configuration.  When installing 
CentOS 7 using the full disk capacity and booting in UEFI mode the machine 
dumps me into a GRUB rescue mode prompt.

  error: disk `,gpt2' not found
  Entering rescue mode...
  grub rescue>

If I use the PERC RAID controller to make the disk smaller ROOTDISK volume of 
100GB in size and then a DATA volume of the rest of the disk the system boots 
just fine so this seems like a GRUB2 issue.  Any thoughts?
