After all I think I'm coming to the same conclusion like Thorsten (#18). The ECKD DASD driver should just be able to handle all ECKD DASD type 3390 disks of any flavour, incl. 3390-ModA EAV and EAV-II DASDs. There is no further dependency.
Since a brand new disk device was used (#20), I assume that the low- level format of the disk (using dasdfmt) could be the missing bit. It either couldn't be found and triggered in the UI or wasn't possible (for whatever reason). May I suggest the following (to prove if this assumption is correct or not): 1) could you redo the installation (again with a brand new disk, that was not yet low-level formatted with dasdfmt), ideally using the updated focal daily live image, available here: http://cdimage.ubuntu.com/ubuntu-server/focal/daily-live/current/ a) that image will later become the 20.04.1 image b) that image will not require a parmfile anymore - if there is no parmfile with the basic network config given, an early component of the installer will just ask about the basic network info interactively in the console 2) start the installation until you reach the initial subiquity text-based UI screen, but do not proceed there, and just hit 'F2' (or F1 for Help and the 'Enter shell') to reach the installer shell. (One of the big advantages of the new installer is that you are now already in a full-fledged live system.) a) find the disk you are going to use with 'lszdev' b) enable that disk manually with 'chzdev -e <device>' c) check with 'lszdev' or 'lsdasd' the assigned block device name (highly likely 'dasda') d) manually low-level format that disk with 'dasdfmt --disk_layout=cdl -b 4096 /dev/dasda' [ e) optionally create a partition using 'fdasd -a /dev/dasda' ] Then I think it's easiest (even if a bit annoying) to restart the installation from scratch, but now proceed with the subiquity text-based UI. If you are now able to complete the installation, it indicates that we need to look at the dasdfmt portion of the installer, if you still struggle to complete the installation, please post the issues here - ideally including the content of /var/log and (in case not empty) /var/crash. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878596 Title: [Ubuntu 20.04] - Install - problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1878596/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
