How to get installer to re-query disk drives

[linush100]

I have an Areca ARC-1224 RAID controller in my system that isn't supported by CentOS 7.1, but I can load the driver module at boot time. The module is built for 7.0 so in order to load in 7.1 it has to be force loaded, meaning that it doesn't load until I go to the shell and issue the modprobe -f command. This is past the point where the installer queries for attached disks, so it doesn't see any and tells me to power off and install a disk.

On previous versions of the installer, I could back up to a previous screen in the install process, then it would re-query the disks, but I haven't found a way to do that on 7.1. Am I going to have to install 7.0 then upgrade, or is there a way make the installer re-query?

Thanks for your help.
