Comment 30 for bug 1878596

Hi Thorsten, I agree.
And that initial low level format issue is currently looked at based on LP 1887669.
Having that in mind I came up with the suggestion in comment #21 (https://bugs.launchpad.net/ubuntu/+source/subiquity/+bug/1878596/comments/21)
asking for a little detour via the installer shell and doing a manual:
'dasdfmt --disk_layout=cdl -b 4096 /dev/dasda'
and
'fdasd -a /dev/dasda'
(replace 'dasda' for yours)
Due to the richness of the live installer one can almost do everything there, and with that suggestion I wanted to make sure (and narrow down) that the issue is really only caused by a not yet low-level formatted dasd.
If formatted this way the installation (and all follow-on installation on this dasd) should work.
