Adding a
qeth
Device
245
If there is an existing configuration file for another device of the same type already defined, the
simplest solution is to copy it to the new name.
# cd ­/etc/sysconfig/network­scripts
# cp ifcfg­eth0 ifcfg­eth1
If you do not have a similar device defined you must create one. Use this example of
ifcfg-eth0
as
a template.
/etc/sysconfig/network­scripts/ifcfg­eth0
# 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
Edit the new
ifcfg-eth1
file.
Remove the HWADDR line for now.
Modify the DEVICE statement to reflect the contents of the
if_name
file from your ccwgroup.
Modify the IPADDR statement to reflect the IP address of your new interface.
Modify the NETMASK statement as needed.
If you want your new interface to be activated at boot time, then make sure ONBOOT is set to
yes
.
Make sure the SUBCHANNELS statement matches the hardware addresses for your
qeth
device.
/etc/sysconfig/network­scripts/ifcfg­eth1
# IBM QETH
DEVICE=eth1
BOOTPROTO=static
IPADDR=192.168.70.87
NETMASK=255.255.255.0
ONBOOT=yes
NETTYPE=qeth
SUBCHANNELS=0.0.0600,0.0.0601,0.0.0602
TYPE=Ethernet
A
qeth
device requires an alias definition in
/etc/modprobe.conf
. Edit this file and add an alias for
your interface.
/etc/modprobe.conf
alias eth0 qeth
alias eth1 qeth
options dasd_mod dasd=0.0.0100,0.0.4b19
Now you can start the new interface:
# ifup eth1
Check the status of the interface:
