<h1 class="topictitle1">Automatically configure virtual devices</h1>
|
|
<div><p>You can configure your Telnet server to automatically create virtual
|
|
devices as needed up to a set maximum.</p>
|
|
<p>You can enable the Telnet server to automatically configure your virtual
|
|
devices and controllers using the QAUTOVRT Devices System Values in iSeries™ Navigator.
|
|
You can specify the number of devices that are automatically started and you
|
|
can specify 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.</p>
|
|
<p>When automatically configuring virtual devices with Telnet, the Telnet
|
|
server does not delete virtual devices and does not delete the devices when
|
|
the session closes. The server does not delete the devices even if the number
|
|
of devices attached to the virtual controllers exceeds the maximum number.
|
|
If the devices already exist on the virtual controller, the Telnet server
|
|
can use them. Telnet server will modify the attributes of an existing device
|
|
to match the client request if that virtual device is requested by name.</p>
|
|
<p>If you have never allowed automatic configuration of virtual devices on
|
|
your server, the Devices System Value Maximum number of devices value is 0.
|
|
A Telnet connection attempt will fail when the number of devices in use exceeds
|
|
the Maximum number of devices. A device in use has the status ACTIVE or SIGNON
|
|
DISPLAY. If you try to sign on, you receive a message (TCP2504) indicating
|
|
that the Telnet client session has ended and the connection is closed. In
|
|
addition, the QTCPIP job in the remote iSeries server sends a message (CPF8940)
|
|
indicating that a virtual device cannot be automatically selected.</p>
|
|
<p>If you change the Maximum number of devices to 10, the next Telnet connection
|
|
attempt causes the Telnet server to create a virtual device. Telnet creates
|
|
this virtual device because the number of virtual devices on the controller
|
|
(0) is less than the number specified in the Maximum number of devices(10).
|
|
Even if you change the specified number to 0 again, the next user attempting
|
|
a Telnet connection succeeds. When a Telnet connection attempt fails because
|
|
the iSeries server
|
|
is not able to create a virtual device, the CPF87D7 message is sent to the
|
|
system operator message queue on the Telnet server.</p>
|
|
<div class="note"><span class="notetitle">Notes:</span> <ol><li>The Telnet server does not automatically delete configured virtual devices
|
|
or named devices, even if the number of devices attached to the virtual controllers
|
|
exceeds the Maximum number of devices.</li>
|
|
<li>The Devices system values specify whether pass-through virtual devices
|
|
and Telnet full screen virtual devices that are attached to the QPACTL<var class="varname">nn</var> controllers
|
|
are automatically configured. This system value does not affect devices attached
|
|
to the QVIRCD<var class="varname">nnnn</var> controllers, because these are not default
|
|
system devices. Typically, QPADEV<var class="varname">nnnn</var> devices are attached
|
|
to QPACTL<var class="varname">nn</var> controllers while named devices, such as NEWYORK001,
|
|
are attached to the QVIRCDnnnn controller.</li>
