In order to prevent communication problems, it is necessary to update the
changed MAC address stored in the related
ifcfg-eth<x>
definition file.
To update the MAC address, proceed as follows:
I
Procedures may differ depending on your Linux OS or the definition file
on the client system. Use the following information as reference. Ask the
system administrator to change the definition file.
Ê
After replacing a network controller or the system board, switch on and boot
the server as described in section
"Switching on the server blade" on
kudzu
, the hardware configuration tool for Red Hat Linux, will launch at boot
and detect the new and / or changed hardware on your system.
I
kudzu
may not launch at boot depending on the client’s environment.
Ê
Select
Keep Configuration
and
Ignore
to complete the boot process.
Ê
Use the
vi
text editor to specify the MAC address in the
HWADDR
section of
the
ifcfg-eth<x>
file:
I
The MAC address can be found on the type label attached to the
system board or network controller.
Example:
In order to modify the definition file for network controller 1, enter the
following command:
# vi /etc/sysconfig/network-scripts/ifcfg-eth1
In
vi
, specify the new MAC address as follows:
HWADDR=xx:xx:xx:xx:xx:xx
Ê
Save and close the definition file.
Ê
For the changes to take effect, you need to reboot the network by entering
the following command:
# service network restart
I
If the system board or network controller offers multiple LAN ports, it is
necessary to update the remaining
ifcfg-eth<x>
definition files accordingly.
Ê
Update the NIC configuration file to reflect the new card sequence and MAC
address.
