Examples

6.10 z/VM guest

These examples illustrate common scenarios for unit record devices.

In all examples the following device nodes are used:
  • /dev/vmrdr-0.0.000c as virtual reader.
  • /dev/vmpun-0.0.000d as virtual punch.
The vmur commands access the reader device, which has to be online. To set it online, it needs to be freed from cio_ignore. Example:
# cio_ignore -r c
# chccwdev -e c
Setting device 0.0.000c online
Done

These scenarios assume that the vmcp module is loaded and that the vmcp command from the s390-tools package is available.
