Console Problems on New Install
Sometimes it is hard to determine what is wrong with your ascii console on a
new install. Some possible things to check:
If it is a plain ascii terminal, like a ibm3151 or
wyse terminal….it is ok to plug into s1. Boot into service mode.
mount a rootvg for maintenance. Select mount all
NOT start without mounting…. When you
are in service mode # set you terminal type.
TERM=vt100;export TERM ....Then cp /etc/inittab to /etc/inittab.orig
Then vi the /etc/inittab file.See below…. you will put a : in front of the line for
:Install_assist and also a : in front of welcome line. Do a write quit (esc wq! )
If it is an ascii terminal, go into smitty select devices select tty select
change show tty, select tty0, then arrow down to stty attribute for run time
and stty attribute for login. Arrow all the way to the end of each line. the
hupcl, echo etc..when you get to the end of the line add a comma and then
the word clocal.... This will be added to both lines then arrow to the very
bottom of the screen…. It will say apply changes to the database only. You
change from no to yes and run by pressing enter Exit smit by pressing f10
or f3 many times.
Try rebooting and see if it corrects it.
Another thing is graphics enabled for the console when you have a 3151 for a console....see below for disabling at the console.
1) Do you have the right keyboard, cable and console set to 9600 8 1 N?
2) Have you defined the console in smitty devices? Have you set the terminal
type?
3) Check inittab for the line for install_assistant or welcome. cp inittab to
inittab.orig and then put a : in front of install_assistant and welcome and see if
it doesn't fix the ascii console.
4) Do you have graphics turned on for this machine but have an ascii
terminal? (see end of doc)
5) Try adding clocal to runtime and login if it doesn't work now. Check cable
and make sure you have an interposer. Make sure you have a full cable, not
just three wires if you can.

---------------------------------------------------------
This will turn graphics off on the console only:
cp /usr/dt/config/Xservers /etc/dt/config/Xservers
vi /etc/dt/config/Xservers
put a # in front of last line
# :0 local local@console ......
To turn graphics off for all users:....
/usr/dt/bin/dtconfig -d (for disable on next reboot)
Useful flags with the dtconfig are -e (for enable) -reset (for reset) and -kill (for
kill now) the e flag is to enable graphics on the next reboot.
If you are running xdm...the process is /usr/lib/X11/Xdm/Xdmconf -d (for
disable on next boot) and -e (for enable on next reboot) You can run one or
the other, not both.
