NIC on the IOU (including onboard NIC)
For replacing IOU itself (replacement of onboard NIC) or expanding, replacing or removing NIC on the IOU,
not only common procedure of IOU replacement but also special procedure before and after powering on or
powering off IOU is needed. Here describes case of replacement of IOU itself. (otherwise add note) 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). For bonding
multiple NIC by using PRIMECLUSTER Global Link Services (GLS), see 'PRIMECLUSTER Global Link
Service Configuration and Administration Guide Redundant Line Control Function' (J2UZ-7781).
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-scripts/ifcfg-
eth*files and the /etc/sysconfig/network-scripts/ifcfg-bond*files), regardless of whether the NIC to be
replaced is a configuration interface of the bonding device.
An IP address does not need to be assigned to unused interfaces. This procedure is for preventing 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.
1. 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".
