Re: [xcat-user] Network boot Memtest with xCAT
I very recently booted a machine into both the RHEL install disc and SystemRescue using the “sanboot” option from iPXE. Here was my example iPXE config file: #!ipxe set base http://192.168.1.116/install sanboot ${base}/isos/rhel-server-7.9-x86_64-dvd.iso #sanboot ${base}/isos/systemrescue-9.06-amd64.iso Looks reasonably similar to the iPXE steps for memtest below, if more complicated. I can’t for the life of me figure out why all of the documentation for doing something like this seems so terrible. It’s very easy to boot a bootable ISO, but most of them have you mucking around with all manner of other stuff as well. Less sure of how to integrate that with xCAT. I was using a Warewulf-based system, but even then, I manually messed with the iPXE config after WW had written it.
