When a qeth group device is set online, an interface name
is assigned to it.
Procedure
To find the interface name of a qeth group device, either:
-
Obtain a list of all attributes for a device by issuing the lszdev command
for the device.
Issue a command of the form:
# lszdev -a qeth <device_bus_id> --info --info
-
Obtain a mapping for all qeth interfaces and devices by issuing the lsqeth
-p command.
- Find out the interface name of a qeth group device for which you know the device bus-ID
by reading the group device's if_name attribute.
Issue a command of the form:
# cat /sys/bus/ccwgroup/drivers/qeth/<device_bus_id>/if_name
Example
# lszdev -a qeth 0.0.a100 --info --info
...
if_name "enca100"
....
or,
using
sysfs:# cat /sys/bus/ccwgroup/drivers/qeth/0.0.a100/if_name
