I am inclined to agree with you, Mark. The fact that the HMC is getting errors trying to read the DVD is not good. That could be due to back level HMC code, depending on the file system format on the DVD. Years ago there used to be an FTP server in the HMC. No longer, not in any useful way. If it's still there, flaming hoops are needed to turn it back on, and very little documentation remains, if any. Frankly, we don't want you using the HMC as a file server in that way. When you boot an LPAR using "Load from Removable Media or Server", the chosen medium or (remote) FTP server connection is bound to that LPAR until you manually release it or you re-activate the LPAR (maybe just re-IPL, I don't remember). The SE loads the memory images (pointed to by .INS file) into the LPAR does a SYSTEM RESTART. That code starts running and uses internal machine interfaces to continue reading files from the DVD or FTP server. (The LPAR can't tell the difference.) If you load from FTP server and point to z/VM, the z/VM FTP server can read the HMC external media if you give the LPAR access to "Mass Media". This is how you could install Linux in an LPAR before Linux and the distros changed the install process to use the internal machine interfaces mentioned above. Please note that the media are the those installed in the HMC itself. You cannot use the web interface along with the your own PC's media (but it sure would be nice!). If you want to use your PC's DVD drive, you need to a) Set up an FTP server on your PC b) Create a VPN connection between your PC and the private HMC-SE LAN.
