12.3. A Note about Linux Virtual Consoles
This information only applies to users of non-partitioned System p systems using a video card as their
console. Users of partitioned System i and System p systems should skip to
Section 12.4, “Using the
HMC vterm”
.
The Red Hat Enterprise Linux installation program offers more than the dialog boxes of the installation
process. Several kinds of diagnostic messages are available to you, as well as a way to enter
commands from a shell prompt. The installation program displays these messages on five
virtual
consoles
, among which you can switch using a single keystroke combination.
A virtual console is a shell prompt in a non-graphical environment, accessed from the physical
machine, not remotely. Multiple virtual consoles can be accessed simultaneously.
These virtual consoles can be helpful if you encounter a problem while installing Red Hat Enterprise
Linux. Messages displayed on the installation or system consoles can help pinpoint a problem. Refer
to
Table 12.1, “Console, Keystrokes, and Contents”
for a listing of the virtual consoles, keystrokes
used to switch to them, and their contents.
Generally, there is no reason to leave the default console (virtual console #6) for graphical installations
unless you are attempting to diagnose installation problems.

12.4. Using the HMC vterm
The HMC vterm is the console for any partitioned IBM System p or IBM System i system. This is
opened by right clicking on the partition on the HMC, and then selecting
Open Terminal Window
.
Only a single vterm can be connected to the console at one time and there is no console access for
partitioned system besides the vterm. This often is referred to as a 'virtual console', but is different
from the virtual consoles in
Section 12.3, “A Note about Linux Virtual Consoles”
.
12.5. The Text Mode Installation Program User Interface
The Red Hat Enterprise Linux text mode installation program uses a screen-based interface that
includes most of the on-screen
widgets
commonly found on graphical user interfaces.
Figure 12.2,
“Installation Program Widgets as seen in
Boot Loader Configuration
”
, and
Figure 12.3, “Installation
Program Widgets as seen in Disk Druid ”
, illustrate the screens that appear during the installation
process.
