Redhat – Install RAID driver on HP DL380 G9

I may have found my answer in the anaconda source after all.

To generate a CentOS 6 compatible driver disk, you can create a squashfs image (other filesystems might also work, but squashfs is by far the easiest to create) with the following layout:

• rhdd3 - a file with a simple one-line comment to describe the disk
• .rundepmod - the presence of this file tells the installer that it should run depmod in order to pick up the modules
• rpms/x86_64 - an optional yum repository containing the kmod RPMs
• lib/modules/2.6.32-220.el6.x86_64/... - the actual kernel modules go here; if the driver disk contains an updated driver of an upstream driver, then the directory structure here should match the upstream kernel module location. The version of the kernel should of course match the version of the installer.

And since a picture is worth a thousand words, here is the sample driver disk we use to kickstart recent laptops that need an updated atl1c.ko driver:

$ unsquashfs -ls driver-disk.dd

Same issue here. Just replace '%_os%/%_ia%'(setup.if2) with 'win2008_r2/x64' or one of the other directories where the drivers are copied to. It worked fine for me. I'm not sure where _os is pointing to. 'set' shows that OS points to 'Windows_NT'. Rather then figuring out where _os is pointing to just replace the variables with fixed (but known) values.
