Because I can't figure out how to get the OS installed otherwise. As it stands currently, I would like to use RAID 50 on both the internal and external arrays. Dell's raid controllers do not allow you to create anything other than one logical drive presenting 100% of the physical raid 50 array size to the OS as a drive, so basically this means my external /dev/sda drive shows as 24 TB, my internal /dev/sdb drive shows as 4.5 TB. So, trying to install RHEL 5.4 x86_64, the LVM wizard cranks up and since the external array is /dev/sda I un-check the box to tell the installer to not look at that 'drive'. I leave /dev/sdb checked which is my 4.5 TB internal drive. Proceed and then the installer tells me my boot drive is managed by GPT but the system cannot boot with GPT and I'm done. As far as I can tell there is not currently a supported way to get RHEL 5 installed with the server in UEFI boot mode, or at least I can't figure it out, I did try putting it in UEFI mode but it refused to boot off an ISO on DVD or a native DVD. So you can't boot off a GPT drive and you can't install to a MBR drive lol. As best I can tell, this leaves me with the only option being get internal to show as /dev/sda, waste a bunch of money by being forced to reconfigure that array as a RAID 1 of two drives for the sole purpose of being able to present a 'drive' of less than 2 TB to the OS so RHEL will install on it using MBR as /dev/sda, do the remaining six disks as RAID 50 and let them become /dev/sdb, keep the external array as RAID 50 /dev/sdc now. I can't accomplish this without the internal raid controller being /dev/sda though so the installer will make it past the partitioning step. Also quite unhappy that the two 750 GB drives that should have been part of my RAID 50 internal will effectively be used to store about 2 GB of boot and OS files but I think I'm stuck.
