[CentOS] CentOS 6.5 install

Hello,  I'm a newbie so here's my question.

I'm trying to install CentOS 6.5 on a HP Proliant 350e server.  This server
has 4x 1TB hard drives.  I'd like to enable the hardware RAID 5 and stripe
all 4 disk into one 3TB logical volume.  Then install CentOS on the 3TB
volume.  However after I install I can't get the server to boot.

I know about the MDOS vs GPT labeling issue.  I've successfully installed
on one (singular) 3TB disk on other servers.  I have modified the partition
tables, relabeling them to GPT, prior to completing the installs.

However I've read that the Anaconda installer still tries to format as MDOS
and after installing a Basic server I cannot get it to boot.

So, what am I missing?  Can I load CentOS on a hardware RAID 5 volume that
is 3TB (usable) or am I stuck with what most Google searches say and load
the OS on one disk and then after use software RAID to RAID 5 the remaining
3 disk into a /data directory?

All help is appreciated.

Thanks    --Kenny
