I'm attempting to install RHEL7 on an old HP ProLiant DL585 G2 server. I boot into the installer through optical media and everything loads correctly as far as I can tell, however the installer does not detect a disk. I suspect this is because the server is using an HP SmartArray P400 hardware raid controller, and the installer doesn't have a driver.
Apparently support for these old drivers (CCISS) was discontinued in favor of newer drivers (hpsa) which do not support the P400. This page links to a sourceforge with various drivers as a possible solution, but I'm unsure how to proceed from there, or if it's possible at all. I'm fairly inexperienced even using Linux, let alone administration. Can someone point me in the right direction?
I'm trying to mimic an offsite environment that our code will be running on later. The install disk was given to us by the admins of the other environment, and has all the packages they are running. Communication is practically nonexistent, and we don't have much time to access the other environment once our window starts, so working out the kinks now is preferable.
That said, installing an older version of RHEL defeats our purposes. Currently this server is running CentOS 6.9, which I installed without any issues.
