This topic explains how to launch a user shell during the Linux Red Hat installation in order to identify network interfaces by their logical and physical names. It assumes you are referring to this appendix from:
Step 3 in the procedure Install RHEL4 From Local or Virtual Media.
You must know the MAC addresses of each EM and NEM port connected to a network; previously recorded per the Linux OS Installation and Network Configuration Worksheet.
If you have not already done so, at the Boot prompt type: linux rescue and press Enter.
The Choose a Language screen appears.
In the Choose a Language screen, select the appropriate language and click OK.
The Keyboard Type screen appears.
In the Keyboard Type screen, select the appropriate configuration then click OK.
The Start Network screen appears.
In the Start Network screen, click No.
The Rescue screen appears.
In the Rescue screen, click Skip.
The user shell appears.
At the command prompt (#) in the user shell, type the following command to display all network interfaces then press Enter.
ifconfig -a
The output of the Linux Red Hat named network interfaces appear, for example see the following sample output.
If you have multiple network interfaces and the output of interfaces scrolls-off the top of the screen, you can display the output per interface.
To view the output per network interface, at the prompt type the following and press Enter:
ifconfig eth#
where #=the interface number. For example, if you type:
ifconfig eth0
The output for eth0 appears, see the following sample:
In the sample output above, the:
eth0
entry in the first column refers to the Linux Red Hat logical named interface. This first column in the output identifies the logical
names Red Hat assigned to the network interface.
HWaddr 00.14.4F.0c:A1:F2
entry in second column (first row) refers to the physical MAC address of the network port.
Do the following:
Refer to the list of MAC addresses previously gathered as part of the Linux OS Installation and Network Configuration Worksheet.
For each network interface, match each physical MAC address with each logical name entry in the ifconfig -a
output.
Record the Red Hat logical network interface name with the physical port MAC address for future reference. You will need to refer to this record when configuring the network interfaces during the Red Hat OS installation.
When you are done, do one of the following to exit the shell.
From the ILOM Remote Console, select Remote Control -> Remote Power Control -> Reset
.
From the ILOM Remote Console, select Ctrl Alt Delete
in the Keyboard menu.
From other consoles, press Ctrl -> Alt -> Delete.
Restart the Linux Red Hat installation program by using the following documentation as a reference:
Procedure Installing RHEL4 From Local or Virtual Media. Restart the procedure, starting from Step 1.
Newly recorded list of the network interfaces that identifies them by their logical and physical names. You will need this list to help you identify which network interfaces you want to configure in the Linux Red Hat installation.
