You can't do much of the work with LVM in text mode.  The only thing you could
do is to either boot into graphics, or use kickstart installation.  You can do
full kickstart file that will give you fully automated installation process
(Anaconda will not prompt for anything), or you could create one that contains
only file system layout information (Anaconda should prompt for options 
missing
in the kickstart file).

If you don't know how to create kickstart file, do a "normal" (no LVM, 
no RAID)
installation.  Anaconda will create kickstart file based on your input (with
partition info commented, but you'd need to replace that part of the file
anyhow) in /root/anaconda-ks.cfg.  Edit that file, place it on a floppy as
ks.cfg, boot from installation CD and on boot prompt type "linux 
ks=floppy". Sit back and relax as your system is automatically 
installed.

The full kickstart documentation is part of Red Hat Enterprise Linux 4 System
Administration Guide:

http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/sysadmin-guide/

The LVM+RAID1 part in kickstart file would look something like this.  
The /boot
partition can not be part of LVM.  If you don't want to have separate /boot
partition, than you'll need to take root partition out of LVM.  Replace 
sda and
sdb with whatever your disks are called.  Add/remove file systems that you
need/don't need.  Change file system sizes to match your needs (and 
disk size).
If you decide to use Grub as boot loader, you'll need to perform some
additional work to make second disk bootable (in case first disk fails).  LILO
will do the right thing out of the box.
