Table 4.10 Confirmation Of Interface Names - Fujitsu PRIMEQUEST 2000 Series Administration Manual

CHAPTER 4 PCI Card Hot Maintenance in Red Hat Enterprise Linux 6
4.6 Hot Replacement of PCI Express Cards
Note
Confirm that each specified interface name is the same as before the NIC replacement.

eth1

16. Edit the saved interface configuration file.
Write a new hardware address to replace the old one. In "HWADDR," set the hardware address of the
replacement NIC in
and after NIC
under bonding, the file contents are partly different, but the lines to be set are the same.
(Example)
DEVICE=eth0
NM_CONTROLLED=no BOOTPROTO=static HWADDR=00:0E:0C:70:C3:40
BROADCAST=192.168.16.255
IPADDR=192.168.16.1
NETMASK=255.255.255.0
NETWORK=192.168.16.0
ONBOOT=yes
TYPE=Ethernet
Do this editing for all the saved interfaces.
17. Restore the saved interface configuration file to the original file.
Restore the interface configuration file saved to the save directory to the original file by executing the
following command.
# cd /etc/sysconfig/network-scripts/temp
# mv ifcfg-ethX
(following also executed for bonding configuration)
# mv ifcfg-bondX
18. Activate the replaced interface.
The method for activating a single NIC interface differs from that for activating the SLAVE interfaces
under bonding.
[For a single NIC interface]
Execute the following command to activate the interface. Activate all the necessary interfaces.
# /sbin/ifup ethX
Also, if the single NIC interface has a VLAN device and the VLAN interface was temporarily removed,
restore the VLAN interface. If the priority option has changed, set it again.
# /sbin/vconfig add ethX Y
# /sbin/ifup ethX.Y
(enter command to set VLAN option as needed)
[For SLAVE under bonding]
Execute the following command to incorporate the SLAVE interface into the existing bonding
configuration. Incorporate all the necessary interfaces.
# /sbin/ifenslave bondY ethX
The VLAN-related operation is normally not required because a VLAN is created on the bonding device.
19. Mount all cables connected to the particular PCIC.
This step is performed by the field engineer in charge of your system.
Note
In GLS configuration with NIC switching way, you do not need to perform this step.
20. Remove the directory to which the interface configuration file was saved.
After all the interfaces to be replaced have been replaced, remove the save directory created in step 6 by
executing the following command.
# rmdir /etc/sysconfig/network-scripts/temp
