Uevents
|
||
|
|
-------
|
||
|
|
|
||
|
|
To generate the events the device must be assigned a role of either
|
||
|
|
a primary or a secondary Bridge Port. For more information, see
|
||
|
|
"z/VM Connectivity, SC24-6174".
|
||
|
|
|
||
|
|
When run on an OSA or HiperSockets Bridge Capable Port hardware, and the state
|
||
|
|
of some configured Bridge Port device on the channel changes, a udev
|
||
|
|
event with ACTION=CHANGE is emitted on behalf of the corresponding
|
||
|
|
ccwgroup device. The event has the following attributes:
|
||
|
|
|
||
|
|
BRIDGEPORT=statechange
|
||
|
|
indicates that the Bridge Port device changed
|
||
|
|
its state.
|
||
|
|
|
||
|
|
ROLE={primary|secondary|none}
|
||
|
|
the role assigned to the port.
|
||
|
|
|
||
|
|
STATE={active|standby|inactive}
|
||
|
|
the newly assumed state of the port.
|
||
|
|
|
||
|
|
When run on HiperSockets Bridge Capable Port hardware with host address
|
||
|
|
notifications enabled, a udev event with ACTION=CHANGE is emitted.
|
||
|
|
It is emitted on behalf of the corresponding ccwgroup device when a host
|
||
|
|
or a VLAN is registered or unregistered on the network served by the device.
|
||
|
|
The event has the following attributes:
|
||
|
|
|
||
|
|
BRIDGEDHOST={reset|register|deregister|abort}
|
||
|
|
host address
|
||
|
|
notifications are started afresh, a new host or VLAN is registered or
|
||
|
|
deregistered on the Bridge Port HiperSockets channel, or address
|
||
|
|
notifications are aborted.
|
||
|
|
|
||
|
|
VLAN=numeric-vlan-id
|
||
|
|
VLAN ID on which the event occurred. Not included
|
||
|
|
if no VLAN is involved in the event.
|
||
|
|
|
||
|
|
MAC=xx:xx:xx:xx:xx:xx
|
||
|
|
MAC address of the host that is being registered
|
||
|
|
or deregistered from the HiperSockets channel. Not reported if the
|
||
|
|
event reports the creation or destruction of a VLAN.
|
||
|
|
|
||
|
|
NTOK_BUSID=x.y.zzzz
|
||
|
|
device bus ID (CSSID, SSID and device number).
|
||
|
|
|
||
|
|
NTOK_IID=xx
|
||
|
|
device IID.
|
||
|
|
|
||
|
|
NTOK_CHPID=xx
|
||
|
|
device CHPID.
|
||
|
|
|
||
|
|
NTOK_CHID=xxxx
|
||
|
|
device channel ID.
|
||
|
|
|
||
|
|
Note that the `NTOK_*` attributes refer to devices other than the one
|
||
|
|
connected to the system on which the OS is running.
