    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

    The command with smitty looks like this:

    Destination TYPE host
    (dotted decimal or symbolic name)

    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?

    Confirm the route using:
    lsattr -El inet0 -a route
    ...

    Then, delete it using chdev

    $ chdev -l inet0 -a delroute .... ..

    Could you please write full command of chdev? Note that I want only to delete static route above!

    For example to delete the default route defined in the example below:

    1. lsattr -El inet0
    authm 65536 Authentication Methods True
    bootup_option no Use BSD-style Network Configuration True
    gateway Gateway True
    hostname sotchax10 Host Name True
    rout6 IPv6 Route True
    route net,-hopcount,0,,,,,,-static,0,10.176.240.1 Route True

    Issue the following command:

    chdev -l inet0 -a delroute="net,-hopcount,0,,,,,,-static,0,10.176.240.1"

    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)!?

    As you can see I am using AIX 5.3 with maintenance level 05

    Does that mean that I should install 08 09 or 10 and apply an APAR?

    you must treat it like a net route.
