SHOW LAN_DEVICE
Displays PEdriver device data. Each device is a local LAN device on the
system, which can be used for NISCA communications.
Format
SHOW LAN_DEVICE landevicename
Parameter
landevicename[,...]
Includes specific LAN devices, which you can use wildcards to specify.
Use the /EXCLUDE qualifier to exclude LAN devices.
Use the SHOW LAN_DEVICE command to display device names.
Qualifiers
/ALL
Includes all device data.
/COUNTERS
Includes device counters data maintained by PEdriver and counters data
maintained by the LAN drivers.
/EXCLUDE=(landevicename[,...])
Excludes specific LAN devices, which you can use wildcards to specify.
/INTERVAL
For the /COUNTERS display, displays the changes to counters since the
last SHOW command.
/n
Displays the nth page. To select a particular page of a
multipage display, specify the number of the page you want to display.
/OUTPUT=filespec
Creates the specified file and directs output to it.
/SDA
Includes LAN device data displayed in SDA format, with all the data
collected in one display for one LAN device.
/SUMMARY
Includes device summary data. This is the default if /ALL, /COUNTERS,
and /SDA qualifiers are not specified.
Example
|
SCACP> SHOW LAN_DEVICE/COUNTERS
|
The command in this example displays device counters.
|
SCACP> SHOW LAN_DEVICE/COUNTERS/INTERVAL
SCACP> SPAWN WAIT 0:0:10
SCACP> SHOW LAN_DEVICE/COUNTERS/INTERVAL
|
The first command in this example displays device counters since the
last SHOW command. The SPAWN command tells the DCL WAIT command to
insert a 10-second delay. The second SHOW command displays counters
after the 10-second period.
|
SCACP> SHOW LAN_DEVICE/COUNTERS
|
The following is a snapshot of the output for SHOW LAN/ALL command.

Displays information about specific SCA ports, which you can use
wildcards to specify. If no portname is specified, all ports on the
node are displayed.
Qualifiers
/EXCLUDE=(portname[,...])
Excludes specific port names from the display. You cannot use wildcards
to specify port names.
/OUTPUT=filespec
Creates the specified file and directs the output of the command to
this file.
Example
The command in this example produces output similar to the following:

Parameter
nodename[,...]
Includes channels to specific nodes, which you can use wildcards to
specify.
Each node name can be accompanied by optional qualifiers to specify
local and remote device names. If no local or remote device name is
specified, all channels associated with the specified node are included.
Use the SHOW CHANNEL command to display node names and local and remote

channel, which you can use wildcards to specify.
Use the SHOW LAN_DEVICE command to display device names.

/EVENT=(event1[,...])
Enables tracing on specific events, which you can use wildcards to
specify. The default is a subset of the events, which includes most
errors and state changes.
Use the SHOW TRACE/CONTEXT command to display event names.
/EXCLUDE=(landevicename/IPinterface[,...])
Excludes specific LAN devices/IP interfaces, which you can use
wildcards to specify.
Use the SHOW LAN_DEVICE/SHOW IP_INTERFACE command to display device
names.
/LOCAL_DEVICE=(landevicename/IPinterface[,...])

channel. You can use wildcards to specify LAN devices/IP interfaces.
Use the SHOW LAN_DEVICE/SHOW IP_INTERFACE command to display device
names.
/REMOTE_DEVICE=(landevicename/IPinterface[,...])

channel. You can use wildcards to specify LAN devices/IP interfaces.
Use the SHOW LAN_DEVICE/SHOW IP_INTERFACE command to display device

specify. The default is to stop no events.
Use the SHOW TRACE/CONTEXT command to display event names.
/SIZE=n
Specifies a trace buffer size of n bytes to be used by
PEdriver for each trace buffer: one for global PEdriver use, one for
each selected channel, and one for each selected VC. n can be
any value between 0 and FFFFFFF.
Examples
| #1 |
SCACP> START TRACE/EVENT=CC_STATE/SIZE=2000
|
The command in this example changes the Trace Channel Control layer
state with a 2000-byte trace buffer.
| #2 |
SCACP> START TRACE/EVENT=ALL NODE10,NODE20
|
The command in this example traces all events but only for the NODE10
and NODE20 channels.
STOP IP_INTERFACE
Directs PEdriver to stop using the specified IP interface.
Caution
If you use STOP IP_INTERFACE to stop the only connection you have to a
cluster, it results in a system CLUEXIT. If you use STOP IP_INTERFACE
to stop the only the connection, connected to a cluster, the system
will CLUEXIT even when you have another connection that uses a
different cluster port. However, if you stop all the IP_INTERFACE
results in excessive activity. When PEdriver loses access to all of its
IP interfaces, it makes an effort to restore cluster IP interfaces
communications by completely re-initializing itself. After the
displayed retry count is exceeded, PEdriver permanently goes offline.
To disable cluster use of all but one IP interface, enter the following
command:
SCACP> STOP IP_INTERFACE * /EXCLUDE=ipinterface
All IP interfaces are stopped except the excluded interface and
PEdriver does not need to be reset.
|
Format
STOP IP_INTERFACE ipinterface[,...]
Parameter
ipinterface[,...]
Includes specific IP interface, which you can use wildcards to specify.
- Use the /EXCLUDE qualifier to exclude IP interfaces.
- Use the SHOW IP_INTERFACE command to display IP interface names.
Qualifiers
/EXCLUDE=(ipinterface[,...])
Excludes specific IP interface, which you can use wildcards to specify.
Example
|
SCACP> STOP IP_INTERFACE WE0
|
This command stops PEdriver on the IP interface WE0.
STOP LAN_DEVICE
Directs PEdriver to stop using the specified LAN device. The original
(and still supported) way to stop PEdriver on a LAN device is
SYS$EXAMPLES:LAVC$STOP_BUS.
Caution
If you use either STOP LAN_DEVICE or SYS$EXAMPLES:LAVC$STOP_BUS to stop
the only connection you have to a cluster, you cause the system to
CLUEXIT.
Even when you have have another connection using a different cluster
port, stopping all LAN devices results in excessive activity. When
PEdriver loses access to all of its LAN devices, it makes an effort to
restore cluster communications by completely re-initializing itself.
After the last LAN device is stopped, the reinitilization produces an
error message similar to the following:
SCACP> STOP LAN *
;%PEA0, Port is Reinitializing ( 49 Retries Left). Check the Error Log.
|
After the displayed retry count is exceeded, PEdriver permanently goes
offline.
To disable cluster use of all but 1 LAN device, enter the following
command:
SCACP> STOP LAN * /EXCLUDE=landevicename
|
All LAN devices except the excluded device are stopped, and PEdriver
does not need to be reset.
|
Format
STOP LAN_DEVICE landevicename
Parameter
landevicename[,...]
Includes specific LAN devices, which you can use wildcards to specify.
Use the /EXCLUDE qualifier to exclude LAN devices.
Use the SHOW LAN_DEVICE command to display device names.
Qualifier
/EXCLUDE=(landevicename[,...])
Excludes specific LAN devices, which you can use wildcards to specify.
Example
|
SCACP> STOP LAN_DEVICE EWA
|
This command stops PEdriver on the LAN device EWA.
STOP TRACE
Stops PEDRIVER tracing. You can read the trace data recorded so far
with a SHOW TRACE command.
To revert trace behavior to initial settings, enter the command SET
TRACE/DEFAULT.
Note
This command is reserved for use by HP Services and OpenVMS Engineering
only. Trace commands and output are subject to change from release to
release.
|
Format
STOP TRACE
Parameters
None.
Qualifiers
None.
Example
The command in this example stops PEDRIVER tracing.
