I'm working on making an offline installer for something I currently build using PXE and RHEL 7. The servers concerned (Dell 14G) need an addition driver loaded for the RAID controller. In the PXE version, I can add
dd=http://somehost/blah.iso to the kernel parameters to load additional drivers at boot time. How do you do the same with local media?
I've got a script that lets me rebuild the ISO with additional content (from here: https://github.com/RedHatGov/ssg-el7-kickstart )
It works as it stands. I am planning to just rip out the 'payload' security hardening stuff and put in my existing kickstart script from the PXE install.
However, if I just put the RAID DUD iso on the disk, and add
dd=cdrom:/megaraid_sas-07.700.52.00_el7.X-2.x86_64.iso to the boot parameters, the installer hangs, saying "Kickstart loaded. Please re-insert installation media". It actually flashes up that message briefly during a normal installation too, so I'm not certain that it's actually relevant.
I can't find much information on using
inst.dd=) with a local file instead of a URL... is it possible? What's the secret? If I just specify
inst.dd with no params (to get the interactive mode), then choose my cdrom /dev/sr0, then it doesn't detect the driver iso (I think it's expecting the whole CD to be the content of that ISO instead of the installer disk)
