No, GPT is a function of the operating system, NOT the hardware, so if the PERC is not recognizing the drive's full capacity, then either your H700 firmware is old (>2TB support was added in the second firmware update for this card) or the drive is not compatible.  Which make/model are you using?
Hello (or rather evening), I have a dell poweredge server R310 (with PERC H700) and 3 hard drives. The first two are SATA disk storage with a capacity of 3TB each (6tb in all) that RAID 1 operation. The third is a 64gb SSD to boot the operating system (I chose to set up Debian). I read some topics that insist to boot using UEFI and put the storage disks to GPT for the OS can fully recognize. So I could access the UEFI interface, with the PERC H700 raid configuration but I can find no indication of the GPT. How do I go about it, is that I missed a step? Hoping someone will help me :)
