Appendix F. Additional Information for S/390 and zSeries Users 67

For more information about conﬁguration of the LCS 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/lcs/<read_device_bus_id>/online

• Deﬁne the alias.

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

of the following:

eth<n> alias lcs

tr<n> alias lcs

• Create a conﬁguration script.

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

ifcfg-eth<n>

ifcfg-tr<n>

The ﬁle should look similar to the following:

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

# IBM LCS

DEVICE=eth0

BOOTPROTO=static

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

IPADDR=9.12.20.136

NETMASK=255.255.255.0

ONBOOT=yes

NETTYPE=lcs

SUBCHANNELS=0.0.09a0,0.0.09a1

PORTNAME=0

TYPE=Ethernet

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

DEVICE=eth<n>

DEVICE=tr<n>

• Activate the device.

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

# ifup eth<n>

# ifup tr<n>

F.6.2.2. Working With the QETH Device Driver

The QETH network device driver supports zSeries 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:

• hsi<n> for HiperSocket devices

• eth<n> for OSA-Express Fast Ethernet and Gigabit Ethernet

• tr<n> 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:

1 2 ... 70 71 72 73 74 75 76 77 78 79 80 ... 85 86
