We have a non production AS400 that I need to change the subnet on, but I'm having issues.
I go into cfgtcp. Option 1 for Interfaces. Stop the interface and wait for it to go inactive, then put a 2 to change it. When I do this it exits the screen and at the bottom says "TCP/IP Interface not changed". It isn't giving me any other error to work off of.
I'm loosely following http://www-01.ibm.com/support/docview.wss?uid=nas8N1017311
, but I don't really want to remove it as they suggest since I'm not changing the IP but just the subnet.
