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.
Besides the vmur device driver and the vmur command, these scenarios require that:
  • The vmcp module is loaded.
  • The vmcp and vmconvert commands from the s390-tools package are available.
