HP Proliant ML 110 G5, CentOS 7 and Smart Array P400

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:

  1. Download drivers from here http://elrepo.org/people/akemi/testing/el7/isos/
  2. Add above driver for CentOS 7 during boot process
  3. Install CentOS 7

This is the theory, in practice it look like this

  1. Download drivers from link provided above
  2. Burn it into USB stick via dd command
  3. Insert CD/DVD with CentOS 7.x and USB stick into USB port
  4. Boot from CD/DVD
  5. During boot proces hit ESCAPE key

    CentOS 7 Boot Screen
    CentOS 7 Boot Screen
  6. Enter command linux dd

    CentOS 7 Linux dd
    CentOS 7 Linux dd
  7. Now we will see screen like this
    CentOS 7 Driver Disk Device Selection (1)
    CentOS 7 Driver Disk Device Selection (1)

    I have choose [1]

  8. Now we have question about choose driver – choose [1]

    CentOS 7 Driver Disk Device Selection (2)
    CentOS 7 Driver Disk Device Selection (2)
  9. Now we have loaded the driver
    CentOS 7 Select Drivers to Install
    CentOS 7 Select Drivers to Install

    Choose [c]

  10. We have loaded the driver and we can proceed with boot
    CentOS 7 Extracting KMOD CCISS
    CentOS 7 Extracting KMOD CCISS

    Choose [c]

  11. Now CentOS 7.x is booting

    CentOS 7 Boot Continues
    CentOS 7 Boot Continues
  12. After that i have proceeded with CentOS 7.x installation.

After steps above I was able to install CentOS 7.x on my old HP Proliant ML 110 G5 server with Smart Array P400.
