Unconfiguring IBM® 4-Port 10/100 Base-TX Ethernet PCI adapters

Edit online

The 4-Port 10/100 Base-TX Ethernet PCI adapter has four ethernet ports and each port must be unconfigured before you can remove the adapter.

Type lsslot -c pci to list all the hot-plug slots in the system unit and display their characteristics.

Type smit lsdenet to list all the devices in the PCI subclass.

A message similiar to the following displays:

ent1  Available 1N-00 IBM 4-Port 10/100 Base-TX Ethernet PCI Adapter (23100020) (Port 1)
ent2  Available 1N-08 IBM 4-Port 10/100 Base-TX Ethernet PCI Adapter (23100020) (Port 2)
ent3  Available 1N-10 IBM 4-Port 10/100 Base-TX Ethernet PCI Adapter (23100020) (Port 3)
ent4  Available 1N-18 IBM 4-Port 10/100 Base-TX Ethernet PCI Adapter (23100020) (Port 4)

Close all applications that are using the adapter you are unconfiguring.
To continue with this procedure, network dump locations must be disabled on the system. To look for and disable network dump locations, do the following:
1. Type the following from a command line:
```
smit dump
```
2. Select Show Current Dump Devices.
3. Check whether any configured dump device shows a network location.
  If not, exit SMIT and you are ready for step 4. To change a dump device to a local location, select Cancel or press F3 and continue with the following step.
4. If the primary dump device shows a network location, change to a local location by selecting Change the Primary Dump Device and then enter the local location in the Primary dump device field.
5. If the secondary dump device shows a network location, change to a local location by selectingChange the Secondary Dump Device and then enter the local location in the Secondary dump device field.
6. When finished, click OK or press Enter.

Type netstat -i to display a list of all configured interfaces and determine whether your adapter is configured for TCP/IP.

Output similar to the following displays:

Ethernet adapters can have two interfaces, for example, et0 and en0.

Use the ifconfig command to remove each interface from the network interface list.
For example, type iconfig en0 detach to remove the standard Ethernet interface, and type iconfig et0 to remove the IEEE 802.3 interface.
Use the rmdev command to unconfigure the adapter amd retain its device definition in the Customized Devices Object Class.
For example, rmdev -l ent0.
Note: To unconfigure the adapter and remove the device definition in the Customized Devices object class, you can use the rmdev command with the -d flag.

Attention: Do not use the -d flag with the rmdev command for a hot-plug operation unless your intent is to remove the adapter and not replace it.
