Kannandgl,
Check and make sure you have no junk files under /etc/rc.config.d/
- You are not supposed to keep any backup file under /etc/rc.config.d/ , like netconf.old ore netconf.08092010 etc , and it may cause the problem.
- If there is any such file move it and reboot and you can check, most of the time that causes the problem.

Also check with this with debug mode & see what you are getting,

sh -x /sbin/rc1.d/S320hostname

Dear RAJ,

1.Today i am coping the file same location ..
2.I am posting the Output # sh -x /sbin/rc1.d/S320hostname.

========================
+ PATH=/sbin:/usr/sbin:/usr/bin
+ export PATH
+ rval=0
+ echo usage: /sbin/rc1.d/S320hostname {start}
usage: /sbin/rc1.d/S320hostname {start}
+ exit 0
========================

Kannan,

Try,

sh -x /sbin/rc1.d/S320hostname start

[Raj D.]

I think you can try with stop and start, and see what happens, this script executes in run level 1, so there may be some dependency ,

- Do you see any error in /etc/rc.log
# cat /etc/rc.log | grep -i -e err -e fail

see in /etc/rc.log for the below portion:


Setting hostname
Output from "/sbin/rc1.d/S320hostname start":
----------------------------



- since when you are getting the hostname as unknown, what changed since last time it was working fine.


- check netconf file again.
# cat /etc/rc.config.d/netconf | grep -v ^#

Kannan,

you have set a wrong host name, you have to limit it to 8 character:

>>
+ uname -S hogisdata2
Nodename must be less than 9 characters
>>



- Change to 8 character hostname:
1. Correct /etc/rc.config.d/netconf entry.
2. Correct /etc/hosts entry.
3. reboot and check.


or
- /sbin/set_parms hostname
And type 8 character hostname, and reboot.

This should fix the issue.



Hth,
Raj.
