|
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 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.
