NIC on the IOU (including onboard NIC)
The procedure describes operations where a single NIC is configured as one interface. It also describes
cases where multiple NICs are bonded together to configure one interface (bonding configuration). Although
name form of NIC differs depending on mounting location of the NIC in SLES12, conventional 'ethX' is used
in below description. 'ethX' should be replaced to actual name of the NIC as necessary.
Notes
- To perform hot replacement in a system where a bonding device is installed, design the system so that it
specifies ONBOOT=YES in all interface configuration files (the /etc/sysconfig/network/ifcfg-eth*files and
the /etc/sysconfig/network/ifcfg-bond*files), regardless of whether the NIC to be replaced is a
configuration interface of the bonding device.
An IP address need not to be assigned to unused interfaces. This procedure is to prevent the device
name of the replacement target NIC from being changed after hot replacement. If ONBOOT=NO also
exists, the procedure described here may not work properly.
2. Confirm where the NIC is mounted.
Confirm the correspondence between PCI Address and interface name of NIC mounted in the IOU which
is confirmed by above "dr show IOU" command.
Example: When PCI Address is "0000:89:00.0".
# ls -l /sys/class/net/*/device | grep "0000:89:00.0"
lrwxrwxrwx. 1 root root 0 Aug 27 16:06 2013
/sys/class/net/eth0/
device ¥
-> ../../../ 0000:89:00.0
The ¥ at the end of a line indicates that there is no line feed.
In this case, eth0 is the interface name which is correspondent to PCI bus address "0000:89:00.0".
Note
You will use the bus address obtained here in steps 2 and procedure after IOU replacement. Record the
bus address so that you can reference it later.
Next, check the PCI slot number for this PCI bus address.
