I have a computer with two WD 750G disks and Scientific Linux release 
7.0 (Nitrogen) installed from SL Live. I simply used the install option 
that appeared after booting it. It asked about the disks to be used and 
I selected both and checked the boxes for a RAID-1 install assuming that 
it would format the the drives as necessary. Was I wrong?

I ask because the resulting install is not what I expected.

]$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb7        50G  5.1G   45G  11% /
devtmpfs        3.7G     0  3.7G   0% /dev
tmpfs           3.7G  148K  3.7G   1% /dev/shm
tmpfs           3.7G   72M  3.6G   2% /run
tmpfs           3.7G     0  3.7G   0% /sys/fs/cgroup
tmpfs           3.7G  1.1M  3.7G   1% /tmp
/dev/sdb8       583G  116G  467G  20% /home
/dev/sdb5       497M  171M  326M  35% /boot

It does not appear to have done what I asked?

Do I need to set up software raid before installing?

What am I doing wrong?

Any help appreciated,

Bob
