ip address changes to each time system is reboot

This is an IBM p9 system with AIX 7.2. End user rebooted the system and it came up with the auto config (normally seen the first time you boot a system) on the console. Unfortunately they then selected auto config tcpip and it did, change ip address of ent0 to After finding that I used smit to change it back to what it was supposed to be. However, now each time the system is reboot if always goes back to! I can't find what is doing this or how to make the change back to the "real" ip permanent.

Any suggestions.

I hate to ask the incredibly obvious, but have you tried setting the correct address with smitty tcpip, selecting "Minimum configuration and startup" ?
Kent Olsen

If you've done that, run smitty chinet, to set the address without initializing other server parameters.

I did the first using smit with no success.  Will give the second a try on Monday.

I suspect the auto config program left a script somewhere that is executed on reboot. I have checked the bootlog, inittab, rc.d but have not been able to identify anything that could be doing it.

I tried "smitty chinet" to set the ip, but that also does not work. On reboot the ip still goes back to

Turned out to be a dhcp issue being set when it should not have been.
