Iain,
When we actually changed ours, we ran into a couple of smaller issues. Your
situation sounds like it might not require all steps as you will still have
the same address.
Make sure to check most of the options on CFGTCP menu. We had the IP on a
couple of other screens as well. In particular, I think it was a route and
host entries that needed changing.
We had application software (FAX) that had "hardcoded" IP addresses. As soon
as we told them we changed the IP, it was a simple process to change. But it
was unnerving to have to deal with that first day when there were a hundred
other things demanding attention. It also turned out they had a FAQ about
this subject (more detailed investigation would have revealed its
existence).
We used DNS extensively to find our AS/400 but a quick bounce of the DNS
servers solved most of the problems. There were at least 6 different names
for our iSeries in DNS. We told some PC users to reboot, others to try
"ipconfig /flushdns".
We had hardcoded firewall settings that needed changing. Many different
filters for various IPs (from and to the old and new box on various ports).
Bounce *NETSVR after changing IP addresses.
Our wireless controller and devices had the IP hardcoded.
The email server was set to accept all mail from the AS400 IP address.
Universal connection needed the wizard re-run to reset its internal IP. I
haven't looked at this for a while. It might not be needed anymore, but if
you can't get PTFs after the change, consider looking into it.
Good luck (it was a fun day for us when we turned up the new box),
Mike Krebs

Subject: Change The IP Address OF Our iSeries
Hi All
Firstly I hope I have the correct forum for this post.
Please bear in mind that you are advising a relatively inexperienced
administrator when it comes to iSeries administration ( I inherited the job
from the person who left - you know the scenario,)
"Who's left now that Fred has gone ?" said the finance controller (he
manages the MIS dept); "AAhh You will do" he said pointing to me.
"But, I have no idea about and iSeries and iSeries Administration. I am just
a programmer".
"No problem" he says. "You can learn as you go along. When can you have the
new iSeries up and running live to replace the old one".
Hence this question.
Can anyone advise me on how I would go about changing the ip address of our
new i520 Express.
It has 2 IP Addresses
XXX.XXX.XXX.221 - The LAN Console
XXX.XXX.XXX.222 - This is the IP address that we use to connect all 5250
connections to and is the one we want to change.
When the time comes I wil turn the old Model 820 off, change the IP address
on teh new Model i520 and IPL it.
This will save us having to run around about 250 PC's changing host files
and also a lot of software processes that have IP addresses embedded into
them (DNSless ADO connections).
Any help will be most gratefully accepted
Best Regards
Iain Wilson
