Create and configure logical units (LUs)

After you configure the connection, you can create the 3270 logical units (LUs). These LUs can be display LUs (terminal emulation), printer LUs, application LUs (LUAs), or downstream LUs. You can create LUs one at a time or in a consecutively numbered range. When you create a range of LUs, all the LUs are given the same properties. You can modify individual LUs after creating them.

• For information about the new IP-DLC Link Service, see IP-DLC Link Service.

• For procedures about creating LUs, see Create LU Pools.

• For procedures about configuring LUs, see the following documentation:

  • Configure a Range of 3270 LUs
  • Assign LUs to Workstations
  • Associate 3270 Printer LUs with 3270 Display LUs
  • Configure APPC LUs for TPs or 5250 Emulation
  • Precedence of Accounts in Determining Default LUs

Modify a 3270 LU

1. In SNA Manager, make sure that the appropriate service is inactive by opening the SNA service shortcut menu, and then select Stop.

2. Expand Connections, and then expand the connection that contains the LU you want to view.

3. Open the shortcut menu for the LU with the properties that you want to view, and select Properties.

4. Select the tab to view or modify the LU properties.

5. If you made changes, on the Action menu, select Save Configuration, and restart the affected service.

   Note

   Restarting the server disconnects all users. Try to schedule configuration changes when they least affect users.
