Unable to delete static route in SMIT

[ej72]

Long story short, during the course of troubleshooting access to a remote system we entered an incorrect route on our AIX server. In smit route the route is displayed as follows:

204.138.99/24 172.16.1.1 UG 0 0 en1 - -

We have tech support on this server through GE (it is a medical billing server and we have no AIX admins on staff) and they recommended the following to permanently remove the route (if we just do route delete it comes back after reboot):

log on as root
smit route
Remove a Static Route
Put the IP you want to remove and the associated default gateway. Network mask isn't needed as it's not indicated by a * for required field.
Then exit back to a command prompt and type in the following
bosboot -ad /dev/hdisk0
Then
bosboot -ad /dev/hdisk1

The problem is that no matter what I type into smit to delete the route it won't accept it. I don't know if I should choose host or net, 204.138.99.0, 204.138.99/24, etc. Everything I have tried returns an error.

Is anyone able to offer assistance with this? Thank you.

Go command line...

First, run the following and locate the route you want to delete:

lsattr -El inet0

Then, remove the route with the following:

chdev -l inet0 -a delroute="<route_info>"

example:

# lsattr -El inet0
authm         65536                                                                    Authentication Methods              True
bootup_option no                                                                       Use BSD-style Network Configuration True
gateway                                                                                Gateway                             True
hostname      aoctoolbox                                                               Host Name                           True
rout6                                                                                  IPv6 Route                          True
route         net,-hopcount,0,-netmask,255.255.255.0,-if,en2,,,,-static,0,192.168.1.21 Route                               True

# chdev -l inet0 -a delroute="net,-hopcount,0,-netmask,255.255.255.0,-if,en2,,,,-static,0,192.168.1.21"

Any ideas?

I've seen that message but the route actually does get deleted sometimes . If not you can try to create a new static route with the correct info and see if it will overwrite the "bad" route.

These can be buggers, if all else fails you can either delete all static routes (be prepared to enter all the routes that do work as well as IP info for your NIC ) or edit the ODM which isn't for the faint of heart
