Thank you so much. The system-config-network-tool has been suggested to me
by the "official" Red Hat support team *gg* - though they know very well
that we have z-linux.
Today I deleted the ifcfg-hsi0 file, and created a new one, vi-editing it very
very very carefully ... and now everything is fine.
As to the MAC-Address: you mean I don't need it? then I'll delete it.
May I ask something else:
we have two zlinux partitions, one for testing and one for production.
In each of these partitions I activated hsi0.
Defined a subnet for them - *ONE* subnet for the two his0's in these
two partitions (same goes for the two eth0's in these two partitions).
Is that all right, the two hsi's "sharing" so to speak one subnet?
Thx and regards
Anna

Subject: Re: "how to add a network device"
The system-config-network tool doesn't really work on System z Linux.
It's works great on x86 but when I last checked it had no idea how to
handle the various types of networking devices available on
s390/s390x. Post-install you usually need to do exactly what you did
to add new network devices - echo things to /sys and then create an
ifcfg file.
A few things that come to mind:
* Did you add the 'alias hsi0 qeth' line to /etc/modprobe.conf
before rebooting?
* If you rename the ifcfg-hsi0 file to ifcfg-hsi0.bak and
reboot/restart networking, does everything else come up correctly? If
not, it would suggest that some of the other ifcfg-* files were munged
or that your ifcfg-hsi0 has conflicting settings.
* Try removing the HWADDR=00:00:00:00 line from the ifcfg-hsi0 file
and rebooting. If it comes up fine and you really want the hardware
address specified in there, run `ifconfig hsi0` and use the specific
MAC address.
