Hi Will,

Simple answer - possibly, but I would advise against it. I'll try to
explain:

I don't know too much about this controller. I've just checked HP's
website and they don't appear to offer a driver for RHEL7 (they do
support RHEL6 though to the current RHEL6u6 release).

Suppose we are able to build a driver for you for RHEL7.1. What happens
when 7.2 or 7.3 is released, and the driver won't build against that
kernel because RH have changed an ABI the driver uses? You are left with
a system that you can't update, and is unsupported.

For this reason I would advice one of two choices:

1. If you absolutely must use your RAID controller, install RHEL6 which
is supported by HP and has over 5 years of supported life remaining from RH.

2. If you must install RHEL7, configure the controller to AHCI mode and
use software RAID.


IMHO either of the options above are preferable to the risk of having an
unsupported system at some point down the road.
