Hi Dave, the principle is the same for all Linux on Z distros (well, the sudo piece is typical for Ubuntu ;-)
Enable the corresponding ccw devices: sudo chzdev -e 0.0.000c-0.0.000e and you'll get these devices: ls -l /dev/vm* crw------- 1 root root 10, 122 Apr 22 08:06 /dev/vmcp crw------- 1 root root 246, 14 May 20 19:47 /dev/vmprt-0.0.000e crw------- 1 root root 246, 13 May 20 19:47 /dev/vmpun-0.0.000d crw------- 1 root root 246, 12 May 20 19:47 /dev/vmrdr-0.0.000c Check that the vmur is in place: lsmod | grep vmur and use it, e.g. sudo vmur receive 1234 ... I suggest to have a look at the "Device Drivers, Features, and Commands on Ubuntu Server" guide: https://www.ibm.com/docs/en/linux-on-systems?topic=commands-ubuntu-server (hopefully 20.04) Chapter 38 - z/VM unit record device driver (page 395) and vmur - Work with z/VM spool file queues (page 672) I hope that this is what you wanted ...
