Console not working on a HP9000/D350

Hi!
we have an old D-Class HP9000/D350. The console is an VXL terminal . A few days ago, right after a reboot, the console ceased to work. We tested the console, same serial cable, with HP9000/D250 box and it worked fine so we think the problem is on the serial port of the server.

So please help me out how to solve this problem.

Hi,

since you tested serail cable and terminal with other server,
possibly the serial may be having some problem.
But, it's very rare that the server console port going bad.

Login to the server by telnet from other server and
first you check whether any hanging process on console terminal.
Even if the getty is running kill the getty to restart the getty.

#ps -t console

also check the /etc/inittab
the entry for console will be similar to the following

cons:123456:respawn:/usr/sbin/getty console console

Then check the /etc/gettydefs for console entry and make sure
the settings match your terminal communication settings.

#
# This entry is used for the console
#

console # B9600 SANE CLOCAL CS8 ISTRIP IXANY TAB3 HUPCL
# B9600 SANE CLOCAL CS8 ISTRIP IXANY TAB3 HUPCL
#Console Login: #console

The above entry in gettydefs is for 9600 baud, 8 bit, no parity.

Hi,

Make sure you have connected to correct port!!
The console port is different if you have access port!

and try to kill getty process running on console.
Also you can try

# echo hello >/dev/console

and see whether you see hello on the console.
If you see hello on console the communication is ok.

Re: Console not working on a HP9000/D350

Hi !

This server is having two serial ports .
on 1st port following info is there

1st- port Access port (8/12/0.0 )
No access port (8/16/4.0)
Serial1/Console

2nd -Serial/UPS (8/20/2)

I have connected serial cable (i.e. modem cable ) to 1st port of the server and other end connected to 25 pin cross cable and this cable is connected to VXL terminal.
this cable i have tested with HP D class 250 server . is it required a specific cable ?
