Hello all,
The network interface for my AIX5.2 is 10Mbps Half Duplex (please dont ask me why!). I want to change to auto-negotioation. When I try to change, it says that the device is in use.
Do I have to kill all the processes that use the network interface? How do I know which are?

Thankx,

You have two choices:

1. Login to machine via console and do (IF it is for en0; if not, adjust):

# ifconfig en0 down
# ifconfig en0 detach
# chdev -l ent0 -a media_speed=Auto_Negotiation
# ifconfig en0 -a state=up
# route add default <default gw>
(above step may be required but not sure)

That takes a few seconds -- how fast can you type (or paste)?

or

2. # chdev -l ent0 -a media_speed=Auto_Negotiation -P
# shutdown -Fr now
(that reboots the machine)

That takes however long it takes to reboot a machine... probably
anywhere between 5 to 15 minutes.

The downtime will be far shorter with option #1, so try to do that if
possible.

I prefer to do this via the at command --> no tcp-connection that can
crash while executing those commands.
