Title:
dasdfmt fails after vary online. syslog show strange
The calls that fail are 'open()' calls. In ubuntu we do not have patches
to s390-tools for dasdfmt code path. Please seek help from s390-tools
upstream developers at IBM.
And call to 'open()' should not require user to have a default shell set
- e.g. it should not be resulting in e.g. system()
Indeed, DASDs with a nomenclature of 019* are often for special use, like 0191,
019D and 019E.
But this is mostly by convention only.
Interesting to know if that applies to this case, too?

Title:

so with fresh and clean disks it works - even if using the not
recommended way to use echo for setting the disks online (rather than
the recommended way of using chzdev):
# during installation in d-i
0.0.0200 (configured)
0.0.0301 (configured) # minidisk 1st part or dasd 2605 mod09
0.0.0302
What I'm trying to ask you, is to only use chzdev. No echos. No
chccwdev. As both echo & chccwdev are redundant if one uses chzdev.
chzdev can online the devices, and make that persistent, and wait for
udev to settle. Doing all three actions in one go.
E.g. $ sudo chzdev -e 0199
The -p flag
Ubuntu defaults to using and supporting chzdev. There are no Ubuntu
releases without chzdev. Please ask other distros to ship chzdev for
cross-distro compatibility and support.
If this is being automated inside scripts, one needs to replicate
everything that chzdev does - including waiting for
May I ask why:
echo 1 > /sys/bus/ccw/devices/0.0.0199/online
was used and not:
chccwdev -e 0.0.0199
Does the usage of chccwdev to set the device only change the situation?
