F.6. Adding a Network Device

The process of adding a network device has changed greatly for Red Hat Enterprise Linux. This is

due in part to the migration of the 2.4 kernel to the 2.6 kernel:

• The proc ﬁle system is no longer used to control or obtain status on network devices.

• The new sys ﬁle system now provides facilities for controlling devices.

• /sys/class/net/<interface_name>/device now provides status on active devices.

<interface_name> is a name such as eth0 or ctc2 that is given to a network interface by the

device driver when the device is conﬁgured.

• /etc/chandev.conf no longer exists.

The sys ﬁle system now contains the information that was placed in /etc/chandev.conf.

• /etc/modules.conf no longer exists.

Network interface alias speciﬁcations are now placed in /etc/modprobe.conf.

Section F.6.1 Adding a qeth Device describes in detail how to add a qeth device to an existing in-

stance of Red Hat Enterprise Linux. Section F.6.2 Quick Reference for Adding Network Devices is a

quick reference for installing other zSeries network interfaces.

F.6.1. Adding a qeth Device

First, determine whether the qeth device driver modules are loaded.

# lsmod | grep qeth

qeth 135240 0

qdio 45360 2 qeth

ipv6 303984 13 qeth

ccwgroup 15104 1 qeth

If the output of the lsmod command shows that the modules are not loaded, you must run the

modprobe command to load them:

# modprobe qeth

Next, create a qeth 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.
