HI
I am just working on a PoC for RHEL7.x with native LPAR and KVM Host
with RHEL7.5 guests.
two things are different
1. use fdasd if you have dasds on your system or fdisk if you are
working with disks.
2. Networkdevices are OSA,s and you have to define 3 address min. on
OSA5 type. There are special commands for check and change the OSA Devices.
3. with RHEL 7.5 there is a beta Version for s390x(64bit) it includes KVM.
I use my RHEL7.5 Versions for demo 90 days

Munif,
The downloads are available from Red Hat, but not sure if you need to have a
contract or not with Red Hat to get access to the downloads. However, the
architecture is s390x and since you don't have KVM or zVM, then the
installation is a little more difficult because you will have to load Red Hat
from the HMC or a FTP server that is accessible from the HMC. But, the actual
installation is pretty straight forward if you have installed Red Hat on
another platform. Other difficulty would be access either DASD or Disk, DASD
being count key data and Disk being SAN disk. Not sure, which one is actually
available to Linux running on bare metal and the same with the networking
components. I know with z/VM, the virtual switch and layer 2 switching works
the best with multiple Linux servers.
The Red Hat manual steps you through the installation of Red Hat on z/VM, but
not sure about native LPARs.
Ubuntu has a web page showing how to install Ubuntu as a Linux LPAR. So, I
would assume installation of Red Hat would be very similar.

Subject: Linux (zLinux) on zSeries
Finally we are getting an IFL from IBM on trial to install Linux on our z13.
No KVM or zVM on the Mainframe. I am looking for any redbooks or IBM
installation document for Linux on zSeries. I am inclined towards Red Hat
Enterprise Linux AS 7 as I expect it to be better integrated with APACHE SPARK.
Hopefully IBM zLinux document can give me comparative studies of different
Linux distribution available on zSeries.
seeking expert advise , experience, gotchas, ROTs.
Regards
Munif
