I had a 6TB Hardware RAID volume that I couldn't boot from (in RHEL5).
What I did was the following:
In my hardware RAID controller I carved off a 1GB volume. That 1GB volume appears to the BIOS and Linux as /dev/sda. The other 5999GB volume shows up as /dev/sdb. Both volumes come from the same RAID6 volume set.
My /dev/sda has one fdisk MBR style partition that uses the whole device, -- it holds /boot. I boot off of it.
My 5999GB volume has a GPT partition table, uses LVM (maybe I could have skipped the GPT partition table altogether), and has Linux installed to it.

Thanks, but we create the partition table automatically.
We need to handle different disc sizes for this it is easier to use the same process for all discs.
