console hung

Ing Meloni — Mon, 19 Nov 2001 16:20:16 GMT

I use as a console for my N4000 server an old vt300 terminal. During the weekend the console hung. I tried everything, even changed cables, changed terminal, rebooted the server, nothing works.
The answer to "ps -ef |grep console" is: root 1375 1 0 14:26:04 console 0:00 /usr/sbin/getty console console

root 41 0 0 14:24:09 console 0:32 vxfsd

My question is: is it normal that with JFS 3.3 vxfsd belongs to terminal console , while on everyone of my other HP-UX boxes (all running JFS 2.4) I have:
root 51 0 0 Oct 22 ? 40:10 vxfsd ?

You need to determine whether you console is completely hung, or if its just the getty

First thing to try is CTRL-B can you get to the GSP. If you can then it looks like a getty problem... If you can't it's more likely to be the console or the cable...

Hi Meloni,

With your console terminal on and connected, kill the getty process and see if the login appears on the console screen.
You can also try to do a cat to the console and see if the communication link is okay. Do a cat /etc/passwd > /dev/console" and try.

Hope this helps.

ctrl-b does not answer.

I have an identical N4000 server, using an identical terminal as console. I tried to switch to the second terminal, as I tried new cables, but no answer as well.

hi,

if cntrl-b is not responding, its most likely that the terminal port is dead. If you have a webconsole installed, can you try using that??

Have a look at the /etc/rc.log file , dmesg and syslog.log output for any errors regarding the console. Also, with the console connected,
from another telnet session redirect a message to the console eg: wall xx
or banner xx >/dev/console.

Regarding the jfs daemon, it should be unattached to any terminal. It could probably be that since the console is not working it couldn't get unattached. Just speculating, but the idea is attack the console issue. If nothing works, get the H/w engineer to have alook at it. Recently one of my n box console ports failed.

Sounds like a broken cable - did you change cables when you checked the other terminal?

On thing you can also do - if you have a HP console you can reset to factory defaults on the console (IIRC pressing 'D' when powering on)

Does the terminal/cable work on other machines?

wasn't it "Ctrl-G" while powering on?

Definitely the console port broke.
We already scheduled the substitution intervention.
Thank you everybody for your support.
