The Configuration Process of the CNA-8000
The configuration process is independent to the operation of the CNA-8000. That is you
can make configuration changes at any time without affecting the functional operation of
the platform. Some changes made to the configuration, primarily those made to the
upstream interface (ESCON, FICON, Host Circuits) will not take place until the next
reboot of the platform or restart of the server program. Some changes will take affect
immediately, such as changing the administrative password. Yet other options, mainly
those affecting TN3270 clients, may be made to take affect immediately by using a
special ‘Apply’ button.
It should be noted that most of the configuration panels have an ‘Update’ or ‘Submit’
button on them. These are used to save the changes made to that specific panel. Changing
values on a panel, then closing the panel (by selecting the X in the upper right corner of
the window or by pressing the Return button, without pressing the Update button first,
will not save your changes, and any modifications will be lost. Warning messages will
normally be displayed prior to your leaving a panel if the changes have not been saved.
The CNA-8000 is capable of storing multiple configurations. Modifications can be made
to whichever configuration is selected to be “currently in use”. Whenever the CNA-8000
is rebooted or restarted, the configuration that is “currently in use” is the one that gets
loaded. Therefore, if you wish to work with a configuration other than the one that
loaded, you need to select the loaded configuration as the “currently in use” configuration
before rebooting again. Information specific to which configuration the platform is
running on can be found on the Server Information panel accessed through the
Maintenance menu.
You are allowed to save a fresh copy of the “currently in use” configuration at any time
from the Save Configuration panel.
