[CentOS-docs] cciss solution for CentOS 7

I've recently come across a thread in the CentOS forums  regarding
the solution to getting hardware requiring the cciss driver, such as HP
ProLiant G5 systems, to install and boot with CentOS 7. The thread was a
start in the right direction, but I believe I've determined a better
workflow and feel that it would benefit the community to have this
published either in the release notes or on the Wiki.
On a system containing an older HPSA (HP Smart Array) adapter, the
following will allow CentOS and/or RHEL 7 to boot and install without
requiring any special drivers.
When booting from the installation media, hit <tab> to edit the boot
command. Add these two keys to the kernel options, and continue to boot
and install the operating system as normal:
On the first reboot after installation, hit <e> to edit the boot command
when you are presented with the grub selection menu. Scroll down to the
line containing the vmlinuz reference, and add those same two keys to
the end of the line.
Once the system is booted, edit /etc/default/grub and add those two keys
to the "GRUB_CMDLINE_LINUX=" line. It should look like this:
rd.lvm.lv=centos_boot/root crashkernel=auto \
hpsa.hpsa_simple_mode=1 hpsa.hpsa_allow_any=1 \
After the grub default is modified, run the following command, and
proceed as you normally would. Your system will now operate through all
kernel updates with the HPSA adapter.
grub2-mkconfig -o /boot/grub/grub.cfg
