S1200v3RPS EFI hangs RAID 4TB GPT

ACamp17 · ‎08-11-2015

I have a S1200V3RPS board that will not boot EFI RAID1 4TB drives. If RAID is not set then it will boot EFI to a GPT 4TB disk. If RAID 1 is enabled then it hangs at EFI Widows boot manager. How do I fix this without having to add additional drives smaller than 2TB to run MBR disks for the boot up drives?

I have loaded the latest Bios from the Intel site. Tried loading boot parameters in EFI boot file.

Hello,

In order to provide accurate assistance, please let us know the model number for the RAID controller you are using for this partition.

Hello Dan_Intel

No dedicated RAID controller. Only on-board ESRT2 LSI controller. On a S2600 based main board it works fine but the S1200V3RPS does not.

Hello,

We would like to inform you that ESRT2 does not support GPT partitions, RSTe will do depending on the chipset for the board. That is the reason why you are not able to boot the system.
