<h1 class="topictitle1">Scenario: Recovery of a console requiring a new console mode setting</h1>
|
||
|
|
<div><p>There may be cases in which you may have to change the console
|
||
|
|
mode in order to recover from a console error. An example of this might be
|
||
|
|
the loss of your network during normal operations.</p>
|
||
|
|
<div class="section"><p>The console mode could be changed using one of several methods,
|
||
|
|
which include:</p>
|
||
|
|
<ul><li>DST or SST menus (delayed)</li>
|
||
|
|
<li>Native macros (delayed)</li>
|
||
|
|
<li>Console Service Functions (65+21) (Immediate)</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>Only the console service functions (65+21) method will automatically
|
||
|
|
take down the old connection and activate all the resources for the new choice.
|
||
|
|
The other two methods may require manual steps to activate the appropriate
|
||
|
|
resources for the new console. These changes also require that the associated
|
||
|
|
resources be available in a state where they can be used. For example, you
|
||
|
|
are using Operations Console LAN and the network fails, the console was in
|
||
|
|
use by your logical partition and you do not have an asynchronous communications
|
||
|
|
card on the IOP tagged for the console. You would have to either move a card
|
||
|
|
or change the IOP tagging to allow a directly attached console to work. If
|
||
|
|
the change is not required immediately, you could also wait for the change
|
||
|
|
to take affect during the next IPL in which case a newly tagged IOP would
|
||
|
|
allow the directly attached console to connect. In this example, however,
|
||
|
|
we are attempting to change the console's connectivity and use another device
|
||
|
|
right now. The recommended method for immediate change is the console service
|
||
|
|
functions (65+21) method. Once that has been successfully performed, the
|
||
|
|
user must sign on again. Since this scenario is from LAN to directly attached
|
||
|
|
console the new console would not get the special signon screen or the Console
|
||
|
|
Information Status screen since it is the only valid console after the console
|
||
|
|
mode change. When the network problem is fixed, the LAN connected devices
|
||
|
|
would go directly to the Console Information Status screen and would not be
|
||
|
|
able to take control as the console without changing the console mode back
|
||
|
|
to LAN. Take over is not available when a device is directly connected as
|
||
|
|
the console since only one connection of this type is allowed by the server.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>Another consideration for choosing the method to change the console
|
||
|
|
mode will be the availability of another workstation. If you are installing
|
||
|
|
using the console then the only method available to you is the console service
|
||
|
|
functions (65+21).</p>
