gpt formatting and uefi booting

[Doll, Margaret Ann]

I have a Dell PowerEdge T120 with 12 4Tb disks. I want to use the first
disk as the system disk and the remaining 11 as a raid 5.

I have the first disk set up as a raid 0. I installed RedHat 6.4 server
software on the first disk. I set up the Dell to use a uefi boot instead
of bios. However, I cannot boot up the new system as the bios does not
support the size of the system disk.

I gather I should set up gpt partitioning instead of the default mbr on
the first disk.

How do I do this?

First, update it to 6.5. Like, yesterday. 6.4 will contain things like the
heartbleed bug, etc.

You can either use the gui gparted, or the user hostile parted. Note that
if you do this, you'll probably have to reinstall - is that ok?

One other option would be to partition disk 0, say, into two 2GB
partitions, and RAID 1 them. Alternatively, what we're doing here for
drives 1TB and over is to make a root partition of 500GB, and the rest as
another partition.

$ parted -a opt

mklabel gpt
mkpart pri (don't be confused - when they say "name, they mean

primary or extended....)

start: 0.0GB (will make sure it's actually aligned)
end: 100%

will make you one big drive.

Thanks, Mark.

I will look for the 6.5 download.

Don't I have to run the parted -a opt on a RedHat system?
Is parted available from the installation DVD?

Yeah, or run yum update.

I'm not sure. We run mostly CentOS at work, so the same as RHEL, and it's
available when we're doing our PXEboot installs.

Thanks again, Mark. The University does have some PXEboot install tools.
I will try those.

Make sure you tell it graphical mode install. I would think that the text
mode just goes and partitions and installs. I forget whether graphical
mode will allow you to do GPT, but what you can do, when it asks for "how
do you want to use the disk", is <f2> (?<f4?) anyway, that gets you to a
command line, and then you can manually partition it, using parted. Then,
after you've created the GPT and partitions, go back to the GUI, and tell
it custom, and then you'll be able to just assign mount points.
