Can not remove static route from AIX 5.3

UNIX AIX
1

Dear all,

I Try to remove a static route with smitty, but recieve this error:

Method error (/usr/lib/methods/chginet):
0514-009 Cannot delete an object from the device
configuration database.
0821-216 chginet: Cannot delete route (net,192.168.30.101,192.168.30.1) from CuAt.

My routing table looks like this (the route I want to remove is marked red):

biete 11:40:48 root:/u01# netstat -rn
Routing tables

Route Tree for Protocol Family 2 (Internet):

The command with smitty looks like this:

Destination TYPE host

  • DESTINATION Address [192.168.30.101]
    (dotted decimal or symbolic name)
  • Default GATEWAY Address [192.168.30.1]

I also tried Destination TYPE net, but error the same.

I tried to delete route with command line, but got some errors:

biete 11:46:02 root:/u01# route delete 192.168.30.101 gw 192.168.30.1
0821-287 gw: bad value
biete 11:46:20 root:/u01# route delete 192.168.30.101
0821-279 writing to routing socket: The process does not exist.
biete 11:46:24 root:/u01#

Can anyone please help me with some tips how to delete unwanted route?

Hi,

try to run

lsattr -El inet0|grep ^route

than pick from the output the route you don't like exactly as it is there i.e.

route host,-hopcount,0,,,,,,10.62.61.5,10.23.32.1 Route True
route net,-hopcount,0,,0,50.120.183.133 Route True

and remove it:

chdev -l inet0 -a delroute="net,-hopcount,0,,0,50.120.183.133"

or

chdev -l inet0 -a delroute="host,-hopcount,0,,,,,,10.62.61.5,10.23.32.1"

Hope this helps

But lsattr -El inet0 | grep route shows only two routes, that I need and do not want to delete (one default one static to specific host)!

biete 09:13:20 root:/u01# lsattr -El inet0 | grep route
route host,-hopcount,0,,,,,,-static,192.168.20.10,192.168.30.1 Route True
route net,-hopcount,0,,0,10.180.1.1 Route True

How can I remove route 192.168.30.101/32 192.168.30.1 (please see netstat -rn output above)!?
