|Issue||When installing a 10G Fiber Daughter Card to replace the 10G Copper Daughter card, it is best to reimage the appliance to automatically generate the necessary udev rules. However, in many cases, a reimage is not possible and sometimes data destructive (in the case of a hybrid appliance). This document will explain how to update these rules when installing a card and not subsequently reimaging the appliance.|
[root@NW10GPKTDEC ~]# cd /etc/udev/rules.d/
[root@NW10GPKTDEC rules.d]# cp 70-persistent-net.rules 70.rules.old
[root@NW10GPKTDEC rules.d]# vi 70-persistent-net.rules
Find the ixgbe lines (e.g. you can type /ixgbe while in vi and press n for the next ixgbe listing) as this will be where you will find the mac addresses of the 10g interfaces.
Replace the mac addresses of em3 and em4 with the mac addresses of your 10g card (you may see them in 70-persistent.rules as ixgbe interfaces but not configured under em3 and em4). Then, write and save your changes: :wq.
Note: You can also find the 10g configured mac and its current configured interface in dmesg with the first half of your 10g mac address
For example, if your 10g mac interface started with 24:6e:96:02 you could find what interface this is configured with the following command:
dmesg |grep 24:6e:96:0e
If you haven't yet configured the ixgbe mac addresses to em3 and em4 in 70-persistent-net.rules dmesg will not see em3 or em4 configured to your new mac addresses.
[root@NW10GPKTDEC ~]# cd /etc/sysconfig/network-scripts/
[root@NW10GPKTDEC network-scripts]# vi ifcfg-em3
[root@NW10GPKTDEC network-scripts]# vi ifcfg-em4
[root@NW10GPKTDEC network-scripts]# service network restart
Update ifcfg-em3 and ifcfg-em4 with the correct MAC to match the MAC configured for em3 and em4 in 70-persistent-net.rules
|Resolution||There is currently no permanent resolution to this issue. It is advised to reimage the appliance after installing the card, but if that is not possible, these steps must be followed.|
