PU definition statement

Code a PU definition statement for each physical unit in the model major node. The model PU definition statement is used to create a PU when the installation exit routine returns the name of the model and the name of the previously undefined PU to VTAM®.

When defining a model major node, see z/OS Communications Server: SNA Customization for information about using the NIDDEF file. The exit routine is required.

Restrictions:
  • The XCF, RTP, VN and EE model PUs do not use the configuration services exit.
  • There is no sift-down from the GROUP definition statement to the PU definition statement. Nor is there any sift-down from the PU definition statement to the LU definition statement.
