6.3.1 Shutdown maintenance for a NIC

The following describes the procedure for swapping a NIC after stopping the system. The MAC address is changed after the NIC is swapped, so you need to modify the operating system configuration file.

  1. Shut down the system.

    # shutdown -h now
  2. Swap the NIC.

  3. Boot the system in single user mode.

  4. Modify the operating system network configuration file. Change the HWADDR item according to the MAC address of the changed NIC.

    # cat /etc/sysconfig/network-scripts/ifcfg-ethX
    DEVICE=ethX
    BOOTPROTO=static
    HWADDR=YY:YY:YY:YY:YY:YY
    HOTPLUG=no
    ONBOOT=yes
    TYPE=Ethernet
  5. In RHEL5, collect the latest hardware information.

    # cp /etc/modprobe.conf /etc/modprobe.conf.bak
    # mv /etc/sysconfig/network-scripts/ifcfg-ethX \
    /etc/sysconfig/network-scripts/ifcfg-ethX.bak
    # /sbin/kudzu
    # cp /etc/modprobe.conf.bak /etc/modprobe.conf
    # mv /etc/sysconfig/network-scripts/ifcfg-ethX.bak \
    /etc/sysconfig/network-scripts/ifcfg-ethX
  6. Reboot the system. If the kudzu selection window is displayed at system startup, select Keep Configuration after Ignore.

    # shutdown -r now
