how to enable console's display?

Hi all, i need help on how can I port the display back to my console. Whenever I boot up, it just stay at the solaris boot up screen.
But I can telnet to the system, just can't get to boot into the working environment?
Hence,I believe that the display has been disabled or so. Is there any commands where I can make the system boot back inot the working environment?

Pls advise.lHelp is greatly appreciated.

From your description, it is a little hard to work out what is going on - You get all the messages about booting from boot device, configuring network ports and this kind of stuff?

If YES, at what point of the boot process does it hang? It will be at some point in the rc3.d boot process, if you can telnet to the machine.

Try this to find out on which start up script it is hanging - In the /etc/rc3.d directory, you will see a number of scripts starting with Sxx (where xx is a number). Starting with the highest number scripts first, introduce a -x flag at the start of the script. This will get the script to run in debug mode.

So at the start of the script where you see this

#!/bin/sh

put this

#!/bin/sh -x

This will put a load of debug output to the screen, which should give you some idea of what scripts are being run.

If NO, then the only thing I can think of is to check that the boot prom parameters, input-device is set to keyboard and output-device is set to screen. To check-

printenv input-device

at OK prompt

Hi,

Do you mean you want to view the bootup messages from your desk, i.e. not at the server's physical console?

This "printenv input-device" doesn't work for
Solaris 7.
The screen where it got hanged is the Solaris screen(Coloured display).I can't see the screen where it identify the devices on boot up.

If you can telnet to the box, run this command for us as root, and post the results:

eeprom

Okay - it looks as though it is your input-device and output-device eeprom settings.

Use the following commands:

eeprom input-device=keyboard
eeprom output-device=screen
init 6

Try setting at the ok prompt:

init 0

Then at the console:

ok input-device keyboard
ok output-device screen
ok nvstore
ok reset

Sorry - typoed -

In a terminal window / telnet session-

# init 0


Then on the console at the ok prompt type this:

ok setenv input-device keyboard
ok setenv output-device screen
ok nvstore
ok reset

BSIM, I thought when you tried using eeprom, to setupthe input and output device, it wasn't changing? What is it that you did differently the second time?

All the answers you got are ok in way or another, but it doesnt solve your problem I guess.

setenv is a prom command only available at the "ok" prompt on the console. Since the you obviously dont have a terminal connected on ttya ( serial port A ) you cant see the ok prompt.
eeprom is available when the os is upp and running but the base problem is that your system does not recogice your graphic board/monitor.
The way the system senses where the console is, is to look if a sun keyboard is connected. If it is not the ttya port becomes console.

1. Remove anything connected to the serial ports, login with telnet and
2. do a "touch /reconfigure". This creates an empty file and the system will do a reconfigure boot at the next reboot.
3. Make sure the Sun keyboard is connected.
4. Reboot the system with init 6 or reboot and it should
be working again.

Besky - I'm not sure that the boot prom params are changed by booting without a keyboard / screen attached. These need to be manually done, although when a machine boots and senses that no keyboard/screen is attached, then it defaults to either terminal port for i/o. I know this is the case for older sparc desktops- don't know for sure about ultra sparcs though.
