Well, we do have a porter box, but it does not allow for low-level installation testing. > I want to install Debian on Mainframe z10 EC, I was successfully booted it > through DVD but the problem is that it is not detecting any of the OSAs.

The trouble I had with OSAs was that too many were detected and hence you are unable to pick the right ones if they don't come first, because of the way the chooser works at that point. One way to workaround that would be to edit the IOCDS to hide the irrelevant devices (you can reenable them post-installation of course). Installation in z/VM with the device numbers that should be used in LPAR mode is usually the easiest way, but I understand that this is not available for those trying Debian directly in LPAR mode.
