Activating an LU

To activate an LU, the major node containing the LU definition must be activated first. If there are no definition errors, all the minor nodes defined in the major node are activated when the major node is activated. If a minor node becomes inactive, it can be activated individually. The following is an example of a VTAM® VARY subcommand to activate a major or minor node:
VARY NET,ACT,ID=node_name
In this example, node_name is the major or minor node name to activate.

See Displaying the status of an LU for an explanation of the active states for a minor node.

See z/OS Communications Server: SNA Operation for a complete description of the VARY ACT subcommand.
