Configuring the InfiniPath Drivers
IB0056101-00 G 5-13
A
Servers typically have two Ethernet devices present, numbered as 0 (eth0) and
1(
eth1). This example creates a third device, eth2.
1. Check for the number of Ethernet drivers you currently have by typing either
one of the following two commands:
$ ifconfig -a
$ ls /sys/class/net
It is assumed that two Ethernet devices (numbered 0 and 1) are already
present.
2. Edit the file
/etc/modprobe.conf (as root); add the following line:
alias eth2 ipath_ether
3. Create or edit the following file (as root):
/etc/sysconfig/network-scripts/ifcfg-eth2
If you are using Dynamic Host Configuration Protocol (DHCP), add the
following lines to
ifcfg-eth2:
# QLogic Interconnect Ethernet
DEVICE=eth2
ONBOOT=yes
BOOTPROTO=dhcp
If you are using static IP addresses, use the following lines instead,
substituting your own IP address for the one in the example. The normal
matching netmask is shown.
# QLogic Interconnect Ethernet
DEVICE=eth2
BOOTPROTO=static
ONBOOT=YES
IPADDR=192.168.5.101 #Substitute your IP address here
NETMASK="255.255.255.0"#Normal matching netmask
TYPE=Ethernet
This change causes the ipath_ether Ethernet driver to be loaded and
configured during system startup. To check your configuration, and make the
ipath_ether Ethernet driver available immediately, type the following
command (as root):
# /sbin/ifup eth2
NOTE:
When multiple QLogic HCAs are present, the configuration for
eth3, eth4,
and so on follow the same format as for adding
eth2 in the following
example.
