node name disappeared

[jayachandran.g]

hi all

i have 2 hp server (rp5740) in cluster noe i have edited its netconf file and changed the date afterhalting the cluster.

then i gave a reeboot once it got rebooted one of the uservers nodename is displayed as "unknown".

now i have reverted back the netconf file then again i gave a reboot but still it is shwoing the same.


i started hostname script manually it is showing "inetd(37) lin 7 syntax error (' "

what may be the possible errors.

possible error: escape characters in netconf -> do
cd /etc/rc.config.d/
mv netconf netconf.sav
strings netconf.sav > netconf
chmod 444 netconf

and test using either reboot or /sbin/init.d/net stop && start (in runlevel 1, if I may ask You for that)

Hi

i have tried what you have told me. but still there the problem is there.

the problem is from rc1.d "S112kminit" is the first place where it is showing the error then it continued. This is according to log files. rc.log

is thee any other solution for this.

What changes did u made to netconf ?

Where is the nodename showing unknown ?

in cmviewcl or in hostname command .

Please check the status of your cluster.

Pls post more details.

For a temporary fix try;

uname -S yournodename

This will only change it until next reboot and is limited to 8 characters.

Also, can you post your inetd.conf file (or just check out entry 7 -- is it ident?)

One other problem could be related to the netconf file. Its a problem with the way some startup scripts run (more importantly how they parse the rc.config.d files);

Here is the code from the hostname startup script:

<-snip->
start)
if [ -f /etc/rc.config ] ; then
. /etc/rc.config
else
echo "ERROR: /etc/rc.config defaults file MISSING"
fi
<-snip->

Since it simply sources *all* files in /etc/rc.config.d, if you have netconf and netconf.sav it will first source netconf, then netconf.sav. So if you had a problem in the original netconf and moved it to netconf.sav, you will still have that problem.

Some startup scripts source their corresponding /etc/rc.config.d file, but to be safe I never make backup copies in /etc/rc.config.d. I always save them to another location.

What did you edit in netconf? Is it hostname?
You should have used set_parms!

Try to simply source netconf and see any error is there.
. /etc/rc.config.d/netconf

view rc.log for possible errors.

If you changed the hostname(s) you should possibly change the corresponding cluster configuration files too.

Hi

i got the solution. According to the rc.log, error was in the script S112kminit.

i ran that script in debugging mode
"sh -x S112kminit".. there i got the place where it got stucked.. and it is not netconf file instead it is some other file.

i copied the same from the other server and i ran it.

now it is working.


thank for your help.

Before i close this case

never have a unwanted file in /etc/rc.config.d dir becos when ever server is coming up kminit takes all the file in consideration.

thanks all
