Set the number of virtual devices

You can read this topic for instructions on configuring the number of virtual devices for the Telnet server and limiting the number of signon attempts allowed.

You can enable the Telnet server to automatically configure a set number of virtual devices and controllers using the QAUTOVRT Devices System Values. You can specify the number of devices that are automatically started and the maximum number of devices that the iSeries™ server automatically configures. The iSeries server configures or creates one device at a time, as needed, up to a specified limit.
  1. In iSeries Navigator, select your iSeries server > Configuration and Service > System Values.
  2. In the right pane, right-click Devices and select Properties.
  3. On the Devices System Values page, enable Pass-through devices and TELNET and select an option for the automatic configuration of virtual devices. The options are:
    • No maximum number of devices - Allow an unlimited number of devices
    • Maximum number of devices (1-32500) - Specify a value between 1 and 32500 for the maximum number of devices that may be configured automatically.
    • Run registered exit program - Call the program registered for the Virtual Device Selection (QIBM_QPA_DEVSEL) exit point when a virtual device needs to be selected or automatically created.

For more programming information and examples, see Technical Studio: Telnet Exit Programs.
