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.

       channelname=* 
       /AFTER=0 
       /EVENT=default settings 
       /STOP 
       /SIZE=512 

/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.

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


SCACP> STOP TRACE
      

The command in this example stops PEDRIVER tracing.
