I have spare IBM HS20, and HS40 Blade servers to use in my project, and I have to choose as modern as possible RHEL release to install on it. My problem is that I don't know exact machine type of this blades (e.g 8843). Is there any possibility to get to know IBM machine type from operating system level? Actually they are running on RHEL3.
dmidecode is not an option for me. It just doesn't work.
