You need to perform several steps before user-space applications
on your Linux® instance
can use a qeth group device.
Before you begin
Find out how the hardware is configured and
which qeth device bus-IDs are on which CHPID, for example by looking
at the IOCDS. Identify the device bus-IDs that you want to group into
a qeth group device. The three device bus-IDs must be on the same
CHPID.
Procedure
Perform these steps to allow user-space applications
on your Linux instance
to use a qeth group device:
- Create the qeth group device.
After booting Linux,
each qeth device bus-ID is represented by a subdirectory in /sys/bus/ccw/devices/.
These subdirectories are then named with the bus IDs of the devices.
For example, a qeth device with bus IDs 0.0.fc00, 0.0.fc01, and 0.0.fc02
is represented as /sys/bus/ccw/drivers/qeth/0.0.fc00
- Configure the device.
- Set the device online.
- Activate the device and assign an IP address to it.
What to do next
These tasks and the configuration options are described
in detail in Working with qeth devices.
