DL165G7 and 6Tb array, cannot seem to use more than 2tb of storage

I have a DL165g7 with a P410/256 SA controller and a 6tb usable internal  RAID-5 array.  I have run into the limitation of MBR formatting but Windows cannot convert the disks to GPT via the GUI or diskpart.exe.  The raid controller uses the only external accessible PCI-e slot so adding an external disk to boot off of is not an option open to me.

 

Is there a way to get this model to use more than 2tb of storage with just the internal disks and the p410 controller?

HI:

 

Some Windows OS do not support GPT,I don't know which OS you're running!

 

You can see this article "Windows support for hard disks that are larger than 2 TB" on Microsoft website,here's a link http://support.microsoft.com/kb/2581408

 

Maybe you can try!

Server OS is 2012.  I have also tried 2008r2 and that also behaves similarily.

Maybe reconfigure two logicaldisks on the SA array, one <2TB for MS-DOS to use and the rest in a larger logicaldisk for data?

Boot devices cannot be GPT as far as I am aware without UEFI (replacement for BIOS).

So you need a smaller logical drive to boot from and then a large D: drive using GPT.

Hello,

in smartarray bios - do you see your array normally = more than 2TB ?
