ask help RAID1, 2 SCSI Drive, RedHat6.1

[George Liu]

Hi

This is a simple question but is difficult for me. I want to install a
bootable-RAID 1 for 2 SCSI hard drive in the same controller. The kernel
is 2.2.12 accompanying OS Redhat 6.1. Here is my RAID plan

                disk partition mount pt.  size        device
                      1      1       /            2400M   /dev/sda1
                      1      2       swap       256M   /dev/sda2
                      1      3       /home    3800M   /dev/sda3
                      1      4       /var        2200M   /dev/sda4

                      2      1       /root      2400M   /dev/sdb1
                      2      2       swap        256M  /dev/sdb2
                      2      3       /home    3800M   /dev/sdb3
                      2      4       /var        2200M   /dev/sdb4

               /dev/sda3 and /dev/sdb3 will be mirrors /dev/md0.
               /dev/sda4 and /dev/sdb4 will be mirrors /dev/md1

I would like to know what's the correct steps in detail to do that.
Thanks a lot.
