Mainframe Architecture Training Slides
by Sarah Julia Kriesch 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)?

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
