Changing IP and hostnames between HP systems

[Gregory Locke]

Hi all:

We will be changing the name of our new rx6600 system to that of our rp4440 system this weekend. The reason is so that the phone system IVR and the bulk of the user scripts will work without a hitch. Yes, I know they are different platforms, PA vs. Itanium, but any compiled programs will be recompiled after the change to reflect the platform.

What is the best way to change the IP and system name?

The "set_parms ip_address" and "set_parms hostname" commands will take care of setting the values everywhere that matter.

Man set_parms for details.

Thanks, Clay. I knew it was something simple.

Hi Gregory,

You can do it the easy way:

/sbin/set_parms ip_address

Which will prompt you for the new settings.

Or the harder way, by manually amending the files to reflect the new ip (and/or name):

/etc/hosts
/ete/rc.config.d/netconf
/etc/mail/sendmail.cw (server name only)

Hope that helps,

Mike.

I should add one cavaet. If the hostname/ip_address tuples change then you need to update your DNS/NIS/NIS+ data to reflect that change but as long as hostname "mickey" still corresponds to "10.1.1.1" eventhough mickey is now an Itanium box then set_parms will do everything necessary.
