    46 It is fairly easy to boot off of 2Tb+ drives in Red Hat EL6, though getting it to work is not obvious. For example, newer servers support UEFI but if you do a default Red Hat EL6 install on an 10G 64-bit Dell Power``Edge server you will get an MSDOS disk label.

For example, [http://en.community.dell.com/dell-blogs/enterprise/b/tech-center/archive/2010/11/23/getting-over-the-2-2tb-bootable-storage-volume-limit-in-rhel-6.aspx newer servers support UEFI] but if you do a default Red Hat EL6 install on an 10G 64-bit Dell Power``Edge server you will get an MSDOS disk label (also note the older HardwareRaid PERC cards only support drives up to 2Tb).

    4849The secret is that the disk label must be GPT (GUID Partition Table) which is not the default for BIOS-based x86 machines (Macs and Itanium use EFI/GPT). Once a GPT disk label exists the installer will use it. I'm not clear on precisely what's going on with grub, the MBR, etc but it works. I did find a utility "gdisk" aka "GPT fdisk" http://www.rodsbooks.com/gdisk/ which has lots of details about GPT.
