6.4.1 Shutdown maintenance for a NIC

The following describes the procedure for swapping a NIC after stopping the system on RHEL7. 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 swapped NIC. If interface names are switched before and after swapping NICs, change the file name and the DEVICE item in accordance with the swapped interface name.

   [For Fast switching mode, NIC switching mode, and GS linkage mode]

   # vi /etc/sysconfig/network-scripts/ifcfg-ethX
   DEVICE=ethX
   BOOTPROTO=static
   HWADDR=YY:YY:YY:YY:YY:YY
   HOTPLUG=no
   BROADCAST=XXX.XXX.XXX.XXX
   IPADDR=XXX.XXX.XXX.XXX
   NETMASK=XXX.XXX.XXX.XXX
   NETWORK=XXX.XXX.XXX.XXX
   ONBOOT=yes
   TYPE=Ethernet

   
   

   [For Virtual NIC mode]

   # vi /etc/sysconfig/network-scripts/ifcfg-ethX
   DEVICE=ethX
   BOOTPROTO=static
   HWADDR=YY:YY:YY:YY:YY:YY
   HOTPLUG=no
   ONBOOT=yes
   DEVICETYPE=hanet

5. Reboot the system.

   # shutdown -r now
