What can I do with this system value?
You may specify the number of virtual devices to automatically configure.
If you do not want to automatically configure any devices, do not select this option (0). This option is equivalent to 0 in the character-based interface. Devices are not automatically deleted to bring the total number down to the specified limit for this system value. Therefore, if you change from a higher value to a lower value, the system does not delete virtual devices.
Before creating devices for Telnet sessions or for passthrough sessions for which the client does not specify the name of the request, this system value will be checked to make sure the new device does not exceed the number specified for this system value. If creation of another virtual device description exceed the limit specified by this system value, the device will not be created for Telnet or passthrough. However, a request for a device for a passthrough session will not check the limit for this system value before creating a device description if the client specified the name on the incoming request (Start Up Record).
The system deletes virtual devices only if they are damaged, or if the device needs to be created again to change its type.
If you select Pass-through devices and Telnet (1), select one of the following options to specify the maximum number of devices that are configured:
- No maximum number of devices (*NOMAX)
An unlimited number of virtual devices may be configured automatically.
- Maximum number of devices (0-32500)
The maximum number of devices that may be configured automatically. Possible values are 0 through 32500 devices. A value of 0 indicates that automatic configuration of virtual devices is off.
- Run registered exit program (*REGFAC)
The program registered for the Virtual Device Selection (QIBM_QPA_DEVSEL) exit point is called when a virtual device needs to be selected or automatically created by the system. If the program registered for the exit point does not exist or if it returns with an error, the system will handle the situation as if this system value is deselected (do not allow virtual devices to be automatically configured).
If this value is selected, the program will be called every time a virtual device is requested by a pass-through or Telnet session.
