Problem removing/adding a network interface

[zaxxon]

Hello,

I have a Fibre Channel adapter running in an AIX 4.3.3 ML 10 box:

  fchan2            37-08             PCI Fibre Channel Adapter

        Network Address.............0000C93E89CC
        EC Level....................CENTAUR 2
        Part Number.................LP9000
        Displayable Message.........Fibre Channel Host Adapter
        Loadable Microcode Level....3914103
        Diagnostic Level............1204100
        Manufacturer................EMULEX
        Device Specific.(YL)........P1-I10/Q1

Upon this device is a driver installed to let me use TCP/IP over Fibre Channel. There was already an IP configured on the new interface "fe2", sitting on top of this fchan2.
To get it going I had to change its charactersitic in SMIT from "loop" to "p2tp". To do this without reboot, I did a rmdev -dl fe2, no problem so far.

The problem now is, that I can't add the "fe2" interface again to give it its IP again. It isn't listed at all when I want to add it in any of the SMIT menues at "tcp/ip, further configuration etc etc".
I can't list the "fe2" with "lsdev -C| grep fe2" anymore, which is ok, but the scary thing is, that I still get it with "ifconfig fe2" (I've set it DOWN and also DETACHED it):

fe2: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX>
        inet 0.0.0.0 netmask 0x0

I also checked for the Location Code of the "fchan2" - there is no other device using the same location code.
I also did a odmget on all parts of the ODM, piped into a grep for "fe2" but had no luck.

Anyone got an idea how to get rid of this "fe2" so I can add it again properly?
Thanks in forward!

your NIC was deleted from the ODM you must rerun cfgmgr to get it back

Already ran it:

root@srarhv01:/usr/tivoli/tsm/server/bin> cfgmgr -vl fchan2
----------------
attempting to configure device 'fchan2'
Time: 0 LEDS: 0x910
invoking /usr/lib/methods/cfgv2fchan -l fchan2
Number of running methods: 1

No new NIC to add under the SMIT menue, nor any new device with "lsdev -C" visible.

Have you tried smit mkinet - you should get a menu - choose Add FC Network Interface

HTH,

Yes, thats the SMIT menue I mentioned. Under AIX 4.3.3 there is no FC Network Interface like on 5.x that you can select. The Interface would be listed under:

  Add a Standard Ethernet Network Interface

Selecting this option just returns a:

0822-056 lsadpnm: No available adapter.

Just being curious I checked all other types of interfaces listed there, none listing anything to add.

I am also in contact with our support - they have no ideas left but a reboot, hoping that cfgmgr might find something instead of using it directly on fchan2 and getting rid of that "fe2" listed with ifconfig.
I will see its outcome tomorrow morning.

Well, try a cfgmgr (plain with no parameters), that's just what would be run on a reboot...

Yes, but this machine is connected to two old EMC² Symmetrix, has two Jukeboxes connected and is running under heavy traffic from about 500 users storing and retrieving scanned images like crazy. I will not dare to run a plain cfgmgr while its running in production.

I do a plain cfgmgr and/or reboot tomorrow when no one will be disturbed by problems that might occure. Thanks for the help so far

The reboot ie. cfgmgr worked. The interface is now porperly implemented, thanks for the help.
