# 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.
In the following example, read_device_bus_id is 0.0.0600, write_device_bus_id is 0.0.0601, and
data_device_bus_id is 0.0.0602. The device is a z/VM virtual NIC and the IP address to be as-
signed to this interface is 192.168.70.69.
# echo 0.0.0600,0.0.0601,0.0.0602 > /sys/bus/ccwgroup/drivers/qeth/group
Next, verify that the qeth group device was created properly:
# ls /sys/bus/ccwgroup/drivers/qeth
0.0.0600 0.0.09a0 group notifier_register
You may optionally add a portname. First, you must check to see if a portname is required:
# cat /sys/bus/ccwgroup/drivers/qeth/0.0.0600/portname
no portname required
The response indicates that you do not need to provide a portname.
To add a port name, check that the devices are offline, and then run the following command:
Note
The device(s) must be offline when you add a portname.
# echo portname > /sys/bus/ccwgroup/drivers/qeth/0.0.0600/portname
Next, bring the device back online:
# echo 1 /sys/bus/ccwgroup/drivers/qeth/0.0.0600/online
Then verify the state of the device:
# cat /sys/bus/ccwgroup/drivers/qeth/0.0.0600/online1
A return value of "1" indicates that the device is online, while a return value '0' indicates that the
device is offline.
Check to see what interface name was assigned to the device:
# cat /sys/bus/ccwgroup/drivers/qeth/0.0.0600/if_name
eth1
To change the value of if_name, run the following command:
# echo new_if_name > /sys/bus/ccwgroup/drivers/qeth/0.0.0600/if_name
You may optionally set additional parameters and features, depending on the way you are set-
ting up your system and the features you require.
