IP Change in HP9000

[Rajesh_20]

Hi All,
Good day.we are using HP9000 Server for Our Warehouse Management System.I have a requirement to change the current IP settings.
In order to do this I tried to use the System administration Tool "sam". But it doesn't work.
Please assist me?

To Modify IP:

Can I edit the IP setting and Sub Net Mask in the File named nectconf in the path /etc/rc.config.d/netconf.

Just by changing this, will it work.

Apart from this do I need to do any other changes anywhere?.

Please help me....

Thanks in Advance,

Rajesh

YOu can do either of the one below

1.Run
#set_parms ip_address
to change it


2.Edit /etc/rc.config.d/netconf and /etc/hosts file

to change the ip-address and subnetmask.
Then do a /sbin/init.d/net stop
/sbin/init.d/net start

Rajesh,

Best way is to follow this procedure....

vi /etc/rc.config.d/netconf & do the changes
vi /etc/hosts & make the changes.....
Stop all your applications

/usr/sbin/rc2.d/net stop
/usr/sbin/rc2.d/net start

or

init 1
init 4/3 (where ever u r) see `who -r`

all the best

Dear Mr Mani

Thanks for your reply. Appreciate you greatly for your immediate response.

I tried to do this but it give me a message "Not Found".

1.Run
#set_parms ip_address
to change it

Well, I shall do the changes in both the files.
Can you please try to explain me what does the net stop and net start does?

Is it for initializing?....

2.Edit /etc/rc.config.d/netconf and /etc/hosts file

to change the ip-address and subnetmask.
Then do a /sbin/init.d/net stop
/sbin/init.d/net start

Thanks once again...

/sbin/init.d contains system startup and shutdown scripts. ./net stop will'stop' the service, and './net start' will start (or initalize) the service.

Hope it helps

Hi Mr KapilRaj

Thanks for your message too. Appreciate you for your time and effort.I shall try this.

It is actually a Production Server and I will be given very short time to do the modification.After changes the system should be back to production....so I need to be prepared for this.

To make it effective, Do I need to restart the system?

Or Just by editing the two files and running the net stop and net start will make it efective.

Thanks, Rajesh

[John Payne_2]

By making the changes and running the start/stop script, the ip address 'should' change. (I generally do not have a problem with this, unless I make an invalid entry... :) )

Also, that file has thing like a default route_gateway. If you are moving your primary address to a new subnet, you will want to change your default route.

Hope it helps

Rajesh,

It is better to restart always , but in mission critical systems we do not get time for that.

My apologies for giving the wrong path as /usr/sbin

It should be /sbin/init.d/net stop and /sbin/init.d/net start

This will work no need to re-boot the box. I will prefer init 1 & then init 3 so that all the other subsystems will do a proper shutdown & startup

All the best (U do not need it) this is a very small change)

Kapil,

I am clear about doing the net stop and net start. But what does the following refer to..

init 1
init 4/3 (where ever u r) see `who -r`

You had also mentioned that you will prefer init 1 & then init 3 so that all the other subsystems will do a proper shutdown & startup

How do I do the init 1 and init 3....is it a command that need to run after doing the net stop and net start?

Thanks, Rajesh

[Rajesh_20]

Hi All

I could not find any comand by the name

net start
net stop

in the path /sbin/init.d

I can see only net command.

When I tried to run the net start command
the system gave me an error message:

$ net start
sh: net: not found.

Why this happens?.....Please assist.Do I need to run as a root? or is it because I am trying to run the command from the wrong place.


I am enclosing the List of Files under init.d directory.

Thanks, Rajesh

Probably net is ont in the path.

Just do a
./net stop
./net start
from the /sbin/init.d/

or use the absolute path.

net is the initialization script and start and stop are its args
If you are changing the ip-add
just make modifications in /etc/rc.config.d/netconf and /etc/hosts
