5 | Uevents | |
6 | ||
7 | To generate the events the device must be assigned a role of either | |
8 | a primary or a secondary Bridge Port. For more information, see | |
9 | "z/VM Connectivity, SC24-6174". | |
10 | ||
9c23f4da | 11 | When run on an OSA or HiperSockets Bridge Capable Port hardware, and the state |
b4d72c08 EC |
12 | of some configured Bridge Port device on the channel changes, a udev |
13 | event with ACTION=CHANGE is emitted on behalf of the corresponding | |
14 | ccwgroup device. The event has the following attributes: | |
15 | ||
16 | BRIDGEPORT=statechange - indicates that the Bridge Port device changed | |
17 | its state. | |
18 | ||
19 | ROLE={primary|secondary|none} - the role assigned to the port. | |
20 | ||
21 | STATE={active|standby|inactive} - the newly assumed state of the port. | |

22 | |
23 | When run on HiperSockets Bridge Capable Port hardware with host address | |
24 | notifications enabled, a udev event with ACTION=CHANGE is emitted. | |
25 | It is emitted on behalf of the corresponding ccwgroup device when a host | |
26 | or a VLAN is registered or unregistered on the network served by the device. | |
27 | The event has the following attributes: | |
28 | ||
29 | BRIDGEDHOST={reset|register|deregister|abort} - host address | |
30 | notifications are started afresh, a new host or VLAN is registered or | |
31 | deregistered on the Bridge Port HiperSockets channel, or address | |
32 | notifications are aborted. | |
33 | ||
34 | VLAN=numeric-vlan-id - VLAN ID on which the event occurred. Not included | |
35 | if no VLAN is involved in the event. | |
36 | ||
37 | MAC=xx:xx:xx:xx:xx:xx - MAC address of the host that is being registered | |
38 | or deregistered from the HiperSockets channel. Not reported if the | |
39 | event reports the creation or destruction of a VLAN. | |
40 | ||
41 | NTOK_BUSID=x.y.zzzz - device bus ID (CSSID, SSID and device number). | |
42 | ||
43 | NTOK_IID=xx - device IID. | |
44 | ||
45 | NTOK_CHPID=xx - device CHPID. | |
46 | ||
47 | NTOK_CHID=xxxx - device channel ID. | |
48 | ||
49 | Note that the NTOK_* attributes refer to devices other than the one | |
50 | connected to the system on which the OS is running. |
