This works if one enables the s390x devices in the early-command section. I tried it with the latest subiquity 20.06.1: https://github.com/CanonicalLtd/subiquity/releases/tag/20.06.1
One either needs to make sure that the installer get's updated to at least 20.06.1 (or latest) or a current daily live image can be used instead: http://cdimage.ubuntu.com/ubuntu-server/daily-live/current/ Sample snippet: early-commands: - chzdev zfcp -e e000 - chzdev zfcp -e e100 - chzdev zfcp-lun -e --online - chzdev -e dasd 162a Closing this for now (project-wise). ** Changed in: ubuntu-z-systems Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879305 Title: [UBUNTU 20.04] Subiquity installer cannot find dasd device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1879305/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
