REMOVING THE NETWORK ADAPTER

Removing a network adapter

To remove a network adapter from the system, use the ifconfig command to
remove the network adapter and interface definitions from the system prior to
physically removing the network adapter. The ifconfig command allows you to
perform configurations and modifications directly to network interfaces.
Note: After running cfgmgr, you may receive an error message as in the
following example:
# cfgmgr

cfgmgr: 0514-621 WARNING: The following device packages are required for
device support but are not currently installed.
devices.pci.ethernet:devices.pci.14100401:devices.pci.ae120100:devices.pc
i.pciclass.020000
If a message such as this appears, you will need to install the additional
filesets listed to enable the network adapter on the system.

To remove a network adapter, perform the following steps:

1. Deactivate (down) all network interface definitions for the network adapter by
running the command:

# ifconfig Interface down

This step is technically not required, but is a good fail-safe to ensure that no
applications or processes are using the specified network interfaces.

2. Remove (detach) all network interface definitions from the network interface
list by running the command:

# ifconfig Interface detach

This step will remove all attributes associated with the network interface from
the system, including attributes like IP address and MTU size.

3. Delete the network interface definitions from the system by running the
command:

# rmdev -l Interface -d

4. Delete the network adapter definition from the system by running the
command:

# rmdev -l Adapter -d

5. Shut down and power off the system (on non hot plug machines).

6. Physically remove the network adapter.

7. Power on the system.
