please post the output of
lsattr -El inet0

If it isnt in there, then I'll try to think of other locations.

And, what version of HACMP are you using?

If the information is in the ODM standard editting is not recommended.

route         net,-hopcount,0,,0, Route                            True

This line states that AIX has one default route, and the router address is

If, after a reboot, you have an extra route defined, you will need to check for programs and/or scripts that are being executed by /etc/inittab. Dont forget the programs started via the rc.d mechanism.

And, considering HACMP - verify the start script(s) of the applications, and also HACMP event customization.

The easiest way to change the default route is to do the following:

1. Use smitty route->Remove Static Route or issue the route -f to flush the routing table.

2. You should see output to the screen informing you that routes are being removed.

3. Then issue the netstat -rn command. You should not see the default in the routing table.

4. Issue the smitty mkroute command. This is pretty straight forward and it will it will add this default route to the ODM database and make it permanent even after a system reboot.

5. Issue another netstat -rn command, you should see your new default route.
