I guess I would like two points of clarification: - does the driverdisk apply to whatever is initially booting (the cobbler image)? Because if *that* can't see the LUNs, then it wont be able to install the system on those LUNs. - if the driverdisk is meant to work on the cobbler image, it isn't. How might I get it to do so. Alternatively, how do I inject the drivers into the cobbler image that bootstraps the installation? - Finally the installation fails properly because it can't find /, > presumably because without the device driver in the kernel, it can't see > the SCSI drive onto which it should be installing itself. > > If I get into a terminal (ctl-alt-f2), I can't see the drives, and > lsmod/dmesg confirm the driver isn't loaded. > > What am I doing wrong?

The way we got systems booting in the first place was to make a live cd with the snic modules already installed in the kernel. Reading the cobbler quickstart ( http://cobbler.github.io/manuals/quickstart/ ) this suggests that a live cd shouldn't be used - only a full DVD. Is that true? cheers L. ------ The most dangerous phrase in the language is, "We've always done it this way." - Grace Hopper
