That's been the default for new installations on z/VM for a while now. However, if a system was upgraded from a version prior to that, the cio_ignore parameter will still be in your kernel parameters, and can cause problems like this. (Or, if someone chose to activate device blacklisting during a new install.) Check /proc/cmdline to see if it's there. If it is, remove it from /boot/grub2/grub.cfg, and /etc/default/grub so that the next time you reboot things should be more reasonable. > At least that's the impression I get reading this > https://www.ibm.com/support/knowledgecenter/en/linuxonibm/com.ibm.linux.z.lhdd/lhdd_r_cio_ignore_cmd.html I'm not sure why you would get that impression from that page. The only references I see to z/VM on that page relate to adding devices to the cio_ignore list after booting, and what happens if that device is detached and later re-attached.
