Error msg while booting the system

[Logan Ramasamy]

One of our system was shutdown for a year. I tried hard booting it. It came with an error message, "can not open ttyd0p7 error No.16". How do I eliminate this error and boot the system. Thanks.

Hi Logan,

Is it error no 6 or 16. If it is 6, it is probably because the system is unable to identify the port 7 (8th port) on your MUX card.

The system should still be sble to boot and you should be able to login into the system from other terminal / console.

Hope this helps.

thanks

Logan-

I'd try first booting to single user mode and checking to make sure that the main files are correct (/etc/hosts, /etc/passwd, and so on). You can check the network configs while you are in there to make sure that it is booting to the right device and it is setup right.

Does the system not boot at all?
Or does it get so far?
Can you get to the point of logging in?

Hi,

Being the device ttyd0p7 sounds like it is
a modem or the modem port complaining. I'd
suggest if you can comment out the entry in
the /etc/inittab file for that device. This
should stop the system complaining about it.
What OS is it? If it hasn't been powered up
for a year, suggest you take the cover off
(whilst powered off) and give it a good clean
Once you have saved the /etc/inittab file
with the change run 'init q' this will tell
'init' to re-examine it's file and continue.
There is not a need to reboot.

Before the system was powered on, we changed the network card to Ethernet card. I think, that is why, it is erroring out.

Booting the system is not a problem. After booting, it keeps on throwing the above 2 error msgs, one for ttyd0p6 and the other for ttyd0p7. The cooresponding entries in the inittab are

a0:3:respawn:/usr/lib/uucp/uugetty -r -t 60 -h ttyd0p7 2400
a1:3:respawn:/usr/lib/uucp/uugetty -r -t 60 -h ttyd0p6 192008nl

I do not know what for these entries are and how do I eliminate these error msgs. As I stated earlier, we have changed the network card to Ethernet card. Any help would be highly appreciated. Thanks.

Hi:

If the box has been off for a year, you certainly don't need uucp. I susprect someone removed the modems from these ports. Let's simply disable them:

In /etc/inittab change the word 'respawn' in these two entries to 'off' using vi.

OLD:
a0:3:respawn:/usr/lib/uucp/uugetty -r -t 60 -h ttyd0p7 2400
a1:3:respawn:/usr/lib/uucp/uugetty -r -t 60 -h ttyd0p6 192008nl
NEW:
a0:3:off:/usr/lib/uucp/uugetty -r -t 60 -h ttyd0p7 2400
a1:3:off:/usr/lib/uucp/uugetty -r -t 60 -h ttyd0p6 192008nl

Then do an init q to reread /etc/inittab and you are done.

Hi,

To stop the getty being executed for a particular port, replace the "respawn" word with "off" in the corresponding line for that port in /etc/inittab file. Save it and do a "init q" for the new inittab entries to come into effect.

Hope this helps.

Thanks

strange baudrates..

there may be a reminant in /etc/uucp/Devices also.

I can't remember if someone mentioned this.

Anyway..
A Clay's reponse should do the trick.

Later,
