Hello folks,

I'll be brief: tried to install new Debian 9 into hercules. IPL stops
when we are about to set up network interfaces.
- Tried with netinstall, xfce and clean IPL from reader.
- Tried with hercules 3.07 and new hyperion

I remember that other distros (RHEL, SLES, Ubuntu) stopped with
comment they require modern hardware (modern CPU versions), but here
I get nothing... it just stops.

Any ideas?

Hello again,

I did it!  Problem is not fixed, but I figured out a workaround:
- install Debian 8.1
- do upgrade with 9 sources.list
- do dist-upgrade after that

proof:
bercik@rescue:~$ cat /etc/issue.net 
Debian GNU/Linux 9

So it's not kernel issue or anything else. It must be something wrong
with installer itself. Should I report a problem somewhere? or we are
only ones who can't do fresh install on hercules?

I'm happy to retest if you can give me the hercules.cnf you used.

Kind regards

Bercik sent me their config and I'm able to confirm the bad behavior.
But it looks to me as if console messages are swallowed. As soon as I
add sleep() calls around all my writes, they succeed. (Which makes
printf debugging very weird.)

And indeed, if I enter ".1" it continues with "The following device
numbers might belong to CTC or ESCON connections.". So all that happens
is that either Hercules or the kernel while sending swallows the output
and you can't actually see the prompts. That also matches the fact that
there are very few startup messages from the kernel altogether.
Essentially every message that doesn't have a bunch of other messages
following (plus the first of the batch) lands on the console, the other
ones are discarded.

That makes me incredibly suspicious that this is a problem in Hercules.
It's also not in the typescript generated by script(1), so it's not
simply overwriting screen content either. I guess we'd need to either
raise this with the Hercules people or instrument Hercules to see where
the lines are missed.

Kind regards
Philipp Kern

I too have experienced the installation problem of Debian 9.2.1 on Hercules ending with the last visible message on the Hercules console log being "Configure the network device".

Reading the assumption of a possible Hercules bug in this thread, I verified the Hercules source ("service.c"), and added some extra debugging code. The result of this (bit more than trivial) exercise is that I cannot find any problems on the Hercules side of things. The fact that Debian 8.9.0 does
this correctly also reinforces my suspicion that this is probably not a Hercules bug, but rather a Debian 9 or Debian 9 installer bug.

As a side note, my successful circumvention to obtain a working Debian 9.2.1 s390x installation was to perform it under VM under Hercules. The final
result IPL's just fine under Hercules without VM, using Hercules Spinhawk
3.13 or Hercules 4.0 Hyperion, both the official Hyperion as well as the SDL Hyperion by "Fish". I am now in the process of (a) trying to find out why
the CTCM device does not always come on-line by itself, sometimes I need to "shutdown -r now" a few times on the Hercules console, (b) learning how to
do a persistent addition of an LCS device, (c) repeating the same
installation with a QETH device under Hyperion, which works, but also not always comes on-line by itself, and if it does, ignores the static IP
address setup but goes DHCP instead. I might need to ask for support later, right now I'm still in the learning phase of things.

Thanks,

Peter J. Jansen

I have downloaded the latest Debian 9 DVD ISO for s390x - debian-9.3.0-s390x-DVD-1.iso - and the installation hang
issue is still present. Is there an actual solution for Debian 9, or can someone point me to where I can download a
Debian 8 s390x ISO?

Thanks!

jerry

In the mean time the hang problem has been fixed, on both the official Hyperion and SDL Fish Hyperion forks, and also on my fork of the Spinhawk Hercules (https://github.com/Peter-J-Jansen/spinhawk; a pull request has been issued).

However, installing Debian 9 directly under Hercules still encounters problems with both the CTCI and OSA layer 2 and layer 3 devices. (I will investigate this further after my vacation, and try to find and fix the problem.) Only the installation of
Debian 9 under VM works fine. The resulting Debian 9 works fine, also when IPL‘d directly under Hercules.
