Mainframe Architecture Training Slides
by Sarah Julia Kriesch 30 Jan '22

30 Jan '22

Hello together, this week we had the topic "The Mainframe Architecture" in our knowledge sharing session. Elizabeth told us, that there are also training slides public accessible. I have added this link to our wiki page: https://www.ibm.com/training/pdfs/The_New_IBM_z15_A-technical_review_of_the… That is a small (but also good) overview about the latest Z15 architecture. There is also a bigger set of technical instruction slides available. Elizabeth has received them and wants to make it public. I want to wait with that because of these default restrictions in such presentation slides: International Business Machines Corporation. No part of this document may be reproduced or transmitted in any form without written permission from IBM. We can publish it as part of our ZSystems team at this point, if we are receiving a written approval from IBM. I am happy, that the author of the bigger (training) slide set is open to forward them. Best regards, Sarah P.S. I have added also a YouTube channel Fit4Mainframe in our wiki. That has been created by one of the leading guys of the Academic Mainframe Consortium.

Problems with s390-tools (configuration or bug)?
by Sarah Julia Kriesch 05 Jan '22

Hello together, openQA can not release openSUSE Tumbleweed at the moment, because the system is hanging after the package installation and the restart with following message: Use the ^ and v keys to select which entry is highlighted. Press ', ' enter to boot the selected OS, `e\' to edit the commands before ', ' booting or `c\' for a command-line. ', ' *(1) openSUSE Tumbleweed ', ' (2) Advanced options for openSUSE Tumbleweed ', ' (s) Start bootloader from a read-only snapshot ', 'Welcome to GRUB!

CP commands are based on s390-tools. If I am looking for the last kexec output, that can be a part for a successful boot process or a "CP IPL" command is required for the integration of z/FCP disks. But we are using DASD disks in this test. I need the more experienced zLinux Users on this mailing list now. We had an update of s390-tools last month. Is that a misconfiguration and we have to add new additional steps for these test cases? Or is that a bug? It seems that GRU>B can be started. The kernel can also be found. Is that a bug in s390-tools then? Thank you for your feedback! Best regards, Sarah

Merry Christmas with snapd
by Sarah Julia Kriesch 26 Dec '21

26 Dec '21

Dear s390x Team, I want to say "Thank you to all of you!" We have achieved a lot this year. We had our first Leap release. We have enabled a lot of new packages for s390x. We have contributed 2 times to hackathons of the Open source Day (by the Grace Hopper Celebration) and received new team members on this way. That all would not have been possible without you. Additionally, I want to congratulate Peace on the successfully passed Cloud Native Nanodegree. Then I will give my colleague Holger an overview of our Release Engineering process between the years. He is interested in the Release Engineering role for PowerPC, which is empty at the moment. If he is allowed to do that as part of his Consulting job, I want to integrate this topic into our bi-weekly meetings of the s390x team. This role was a one-man show (from IBM-side) in the past. You can work better and receive a better introduction in a team. So we will work as a team specializing in IBM technologies. Then we have founded the Linux Distributions Working Group [0] together with other community distributions via the Open Mainframe Project. Our Kick-off meeting will be on the 10th January 2022 [1]. I hope that we can improve the behaviour with the collaboration together with IBM and the support with that. The focus is on community distributions at the moment. But I believe, that we can open it to all distributions, who are feeling to be affected by such behaviour in the future. I have got a special Christmas present for you all as s390x users. :-) I have enabled snapd for s390x (and again for PowerPC). You can install it with the following commands on openSUSE Tumbleweed: sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Factory_… snappy sudo zypper --gpg-auto-import-keys refresh sudo zypper install snapd source /etc/profile #or relogin sudo systemctl enable --now snapd sudo systemctl enable snapd.apparmor.service We have got 860 additional software packages for s390x available now. I have added the list. I hoped to make .Net 6 for IBM Z [2] as a Christmas present on this way available for you. But that has been only available for the other architectures as arm and amd64 [3]. The alternative installation script by Microsoft is indicating s390x as x86 with the 64bit architecture. Therefore, the wrong tar archive will be installed. If they do not provide a tar archive for s390x after my bug report, I will use our former Open Source Day Mentees (5 Microsoft employees) to bring it forward. Anyway, have a lot of fun experimenting with these new available packages via snap. :-) I had used snap as a Student for using the zoom client on openSUSE as an example (required for university lessons during Covid). That was not available in our openSUSE repositories. I wish you a Merry Christmas and a happy new year!
