Configure the ports on SLES nodes - R840 servers
Configure the ports on Linux-based (SLES type) nodes.
Procedure
1. Configure the /etc/udev/rules.d/70-persistent-net.rules file to match the following:
The 1 GB port is em3 and is used for management.
l
The 10 GB data ports are em1 (Data 1) and p1p1 (Data 2) .
l
2. Use vi to edit the /etc/udev/rules.d/70-persistent-net.rules file and replace all the Eth names
with the correct allocation:
The 1 GB port is em3 and em4.
l
The 10 GB ports are em1, em2, p2p1, p2p2.
l
The following example shows how the /etc/udev/rules.d/70-persistent-net.rules file will look after
the eth ports are configured:
3. After updating the 70-persistent-net.rules files, reboot the node using the reboot command.
4. After the node comes up, log in again to the console.
5. Create the ifcfg-emX files for all interfaces.
Note: A good way to create a file is using the cp and echo commands:
Example:
cp /etc/sysconfig/network/ifcfg-em3 /etc/sysconfig/network/ifcfg-em4;
echo "" > /etc/sysconfig/network/ifcfg-em4;
6. Create the following files:
Eth configuration files for 1 G interface as ifcfg-em3
l
Eth Configuration files for 10 G interface as (first 10 G NIC) ifcfg-em1 & ifcfg-em2
l
Eth Configuration files for 10 G interface as (second 10 G NIC) ifcfg-p2p1 & ifcfg-p2p2
l
Refer to the following commands as examples for how to populate each file. Replace each use of "X" with the
relevant interface, subnet or IP address.
