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? ** Also affects: ubuntu-z-systems Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1643527 Title: dasdfmt fails after vary online. syslog show strange message "The disk layout of the DASD is not supported" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1643527/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
