Installation guide

The QETH network device driver supports IBM System z HiperSockets, OSA-Express Fast Ethernet,
Gigabit Ethernet (including 1000Base-T), High Speed Token Ring, and ATM features (running
Ethernet LAN emulation) in QDIO mode.
Based on the type of interface being added, the QETH driver assigns one of three base interface
names:
hsin for HiperSocket devices
ethn for OSA-Express Fast Ethernet and Gigabit Ethernet
trn for Token Ring
The value n is an integer that uniquely identifies the device. n is 0 for the first device of that type, 1 for
the second, and so on.
Load the device driver:
# modprobe qeth
Create the group device:
# echo read_device_bus_id,write_device_bus_id,data_device_bus_id >
/sys/bus/ccwgroup/drivers/qeth/group
Due to the length of this command, it has been broken into two lines.
Configure the device.
For more information about configuration of the QETH driver, refer to the following:
http://oss.software.ibm.com/developerworks/opensource/linux390/docu/lx26apr04dd01.pdf (Linux
for IBM System z and S/390 Device Drivers, Features, and Commands)
Set the device online:
# echo 1 > /sys/bus/ccwgroup/drivers/qeth/read_device_bus_id/online
Define the alias.
Based on the type interface being added, add a line to /etc/modprobe.conf that is like one of
the following:
hsin alias qeth
ethn alias qeth
trn alias qeth
Create a configuration script.
Create a file in /etc/sysconfig/network-scripts/ with a name like one of the following:
ifcfg-hsin
ifcfg-ethn
ifcfg-trn
The file should look like this:
/etc/sysconfig/network-scripts/ifcfg-eth0
