6.10 LPAR mode z/VM guest

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 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

# cat /sys/bus/ccwgroup/drivers/qeth/0.0.a100/if_name
