68 Appendix F. Additional Information for S/390 and zSeries Users

# 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 zSeries and S/390 Device Drivers, Features, and Commands)

• Set the device online:

# echo 1 /sys/bus/ccwgroup/drivers/qeth/<read_device_bus_id>/nline

• Deﬁne the alias.

Based on the type interface being added, add a line to /etc/modprobe.conf that is like one of

the following:

hsi<n> alias qeth

eth<n> alias qeth

tr<n> alias qeth

• Create a conﬁguration script.

Create a ﬁle in /etc/sysconfig/network-scripts/ with a name like one of the following:

ifcfg-hsi<n>

ifcfg-eth<n>

ifcfg-tr<n>

The ﬁle should look like this:

/etc/sysconfig/network-scripts/ifcfg-eth0

# IBM QETH

DEVICE=eth0

BOOTPROTO=static

HWADDR=00:06:29:FB:5F:F1

IPADDR=9.12.20.136

NETMASK=255.255.255.0

ONBOOT=yes

NETTYPE=qeth

SUBCHANNELS=0.0.09a0,0.0.09a1,0.0.09a2

TYPE=Ethernet

Based on the type interface being added, the DEVICE parameter should be like one of the following:

DEVICE=hsi<n>

DEVICE=eth<n>

DEVICE=tr<n>

• Activate the device.

Based on the type interface being added, issue an ifup command:

# ifup hsi<n>

# ifup eth<n>

# ifup tr<n>
