Recently i had to reinstall my old (but still working) server. I have bought Smart Array P400 instead of my old Smart Array E200, added new harddrives (WD Caviar Black 1TB x 2). And there was an issue regarding that on CentOS 7.x (RHEL 7.x) there is no more drivers for that controller. This was bad for me.
I have started to google the internet and have found a solution for this:

Solution was simple:
- Download drivers from here http://elrepo.org/people/akemi/testing/el7/isos/
- Add above driver for CentOS 7 during boot process
- Install CentOS 7
