Upgrade and Maintenance Manual 89
Basic software procedures
5.2.13 Updating the NIC configuration file in a Linux and
VMware environment
In order to prevent errors caused by changing network device names ( eth<x> ),
it is recommended to store the MAC address (hardware address) of a network
interface card in the related NIC configuration file of the Linux/VMware OS.
When replacing a network controller or the system board with onboard LAN
controllers in a server running Linux/VMware OS, the MAC address will change
but not automatically be updated in the definition file.
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/VMware 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" on page 60 .
The hardware configuration tool for Red Hat Linux, will launch at boot and
detect the new and/or changed hardware on your system.
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.
5.2.14 Resuming BitLocker functionality
If BitLocker Drive Encryption has been suspended for maintenance purposes
(see section
