Alan,
Thank you for very clear and thorough explanations.
That helped me a lot.
BTW: FTP access is more tricky: file.INS is loaded by HMC, further load
process is beeing performed by SE.
So, someone could connect to ftp server from "external" network, pick
(confirm) the system to be IPLed and... nothing happens.
Frotunaltely I went through the process few years ago, on z990 - then
the LRMS icon was available on SE, not on HMC. That was some suggestion
about the network. ;-)
Regards

"Load from Removable Media or Server" -
installation from DVD or ftp server. There is no place to put load
parameters.
Quite speciic scenario, but installation process is possibly older than
"Integrated 3270 Console", so other consoles for that process should be
also an option.
The machine has two ways to IPL:
1. The traditional LOAD function -- Choose channel-attached device or a remote
SCSI LUN. Uses traditional IPL I/O architecture.
2. Load from Removable Media or Server (LRMS) -- Choose from media-provided
pick list. Selected program is loaded into memory and a SYSTEM RESTART is
performed.
You only use the LOAD FROM REMOVABLE MEDIA OR SERVER (LRMS) function for
installation,and that's the only time the integrated 3270 is required. It is
z/VM that requires the integrated 3270. As After that, you LOAD the LPAR in
the traditional manner.
Please note that when using LRMS with an FTP server that the server must be on the
HMC-SE LAN segment. That is, the SEs are the machines doing the FTP and the SE
must be able to reach the FTP server. Because the HMC will not perform routing,
the suggested configuration is for your fave FTP server to have an interface on it
with a VPN into the LAN segment used by the HMC & SEs.
