Sun enterprise 420R boot issue

Hi,
I am using sun enterprise 420R server. Problem is on the monitor i am not able to see anything. I tried Serial connection, on terminal(using serial) i could see that POST(power on start tests) tests are being done, after that "timeout waiting for arp rarp packet" message keep displaying forever and it never comes up.
Boot device is set to net.
By pressing CONTROL+B also not able to get ok prompt.
i could not disable the POST tests by pressing STOP+A.

Can anyone pls help how to change boot device to disk and how to get ok prompt.

Thanks in advance

On serial line stop+a is not working. If I remember right, a ~# should do the trick. If you are connected via a RSC card, there should be a break command from within the controller.
Also, while using serial connection, make sure there is no monitor and external keyboard connected. And check that the key on the front panel is not in "locked" position!

Thank you, now i could get the ok prompt with break.

one more prob. i have is, not able to change the boot-device.
It was set to net and i have changed to disk with " setenv boot-device disk " command at ok prompt.

when i give "printenv boot-device" it shows disk, but again it is trying to boot from net

after post tests it shows like below

Boot device : net File and args
timeout waiting for arp rarp packet boot net
.
.
.

can some help how to change the boot-device to disk.

Thanks in advance,
kk

I think "screen" parameter may be wrong. See this thread from sometime ago

http://www.unix.com/solaris/228271-alom-console-3.html

Where DukeNuke2 knew the answer and put me right on this.

I still miss the devalias output.

sorry, system is hung so i can't give any command to server.

Now i am not getting ok prompt also(i have changed output-device to screen and after that it is not coming up, i mean not coming till ok prompt).

earlier output device was tty screen. can you please help me how to resolve this.

Did you change the input-device also? If not, the serial line should still work for input and you can try (blind) to set the output-device back to TTY. You can also try to type set-defaults and reset-all after that. If nothing works, you have to get a screen connected to the system.

No, i didn't change input device. it is as below.

input-device tty keyboard keyboard

i can't modify the settings becase it is not taking any commands (server getting stuck at some point and not giving ok-prompt even with the break). Using serial port i can see the log, server will come upto some point and then stuck where it will not take any commands.

can you please give some more info on how to connect screen, u mean monitor? if so, i have connected and monitor showing "input not supported".

i can give the log if needed.

What DukeNuke2 has said is that, if you haven't changed the input device, imagine that you do have an "ok" prompt and type the command "blind". If the hardware IS listening to the input device (keyboard) you can still set the output device. Worth a try.

Thank you, it seems there is hardware problem too. Checking with the sun support.
