SHOW/ADAPTER (VAX Only)

On VAX systems, displays all the nexus numbers and generic names on the adapter.

Use of the SHOW/ADAPTER command requires the CMEXEC privilege.

Format

SHOW/ADAPTER

Parameters

None.

Qualifiers

None.

Example


SYSGEN>  SHOW/ADAPTER

The following example is a sample display produced by the SYSGEN SHOW/ADAPTER command: 


CPU Type: 11/780

 Nexus Generic Name or Description
   1   16K memory, non-interleaved
   3   UB0
   8   MB0
   9   MB1

SHOW/BUS (VAX Only)

On VAX systems, displays all the nexus numbers and generic names on the adapter. On Alpha systems, use the SYSMAN command IO SHOW BUS.

Use of the SHOW/BUS command requires the CMEXEC privilege.

Format

SHOW/BUS

Parameters

None.

Qualifiers

None.

SHOW/CONFIGURATION (VAX Only)

On VAX systems, displays information about the device configuration.

Use of the SHOW/CONFIGURATION command requires the CMEXEC privilege.

Format

SHOW/CONFIGURATION

Parameters

None.

Qualifiers

/ADAPTER=nexus

Specifies the number of MASSBUS or UNIBUS adapters to be displayed. The nexus value can be expressed as an integer or with one of the generic names listed by the SYSGEN command SHOW/ADAPTER.

/COMMAND_FILE

Specifies that SYSGEN formats all the device data into CONNECT/ADAPTER=adapter-spec commands and writes the commands in an output file you specify. In this way, you can completely reconfigure a system for UNIBUS devices without the use of the SYSGEN command AUTOCONFIGURE.

/OUTPUT=file-spec

Specifies the file specification of an optional output file. If you specify the /OUTPUT qualifier but omit the file type, the default is .LIS. However, if you specify the /COMMAND_FILE and /OUTPUT qualifiers together, the default file type for the output file is .COM.

Description

The SHOW/CONFIGURATION command shows devices by name, number of units, nexus number, and adapter type, as well as by control and status register (CSR) and vector addresses. You can specify an output file with the /OUTPUT qualifier.

Note that you can remove a device from the middle of the floating addresses without completely redoing jumpers to the CSR and vector addresses of the remaining devices by following these steps:

  1. Modify your site-independent STARTUP.COM file to invoke the command file specified with the /OUTPUT qualifier instead of entering an AUTOCONFIGURE ALL command.
  2. Enter the SHOW/CONFIGURATION/COMMAND_FILE/OUTPUT command to format and save the device data. If you must bring the system down for service and remove a board, SYS$SYSTEM:STARTUP.COM invokes your output file as a command procedure when the system reboots, and the system automatically configures UNIBUS devices and MASSBUS devices for you.

Remember that a new version of SYS$SYSTEM:STARTUP.COM is provided with each major release, so you would need to repeat any modifications you have made to SYS$SYSTEM:STARTUP.COM after you install the new version.

Note
Although this technique can offer a convenient short-term solution, use AUTOCONFIGURE ALL when possible.

SHOW/STARTUP

Displays the name of the current site-independent startup command procedure.

Format

SHOW/STARTUP

Parameters

None.

Qualifiers

None.

Example


SYSGEN>  SHOW/STARTUP
Startup command file = SYS$SYSTEM:STARTUP.COM

This command displays the name of the site-independent startup command procedure.

SHOW/TURBOCHANNEL (VAX Only)

On VAX systems, displays the nexus number of a device on the TURBOchannel.

Format

SHOW/TURBOCHANNEL

Parameters

None.

Qualifiers

None.

Example


SYSGEN>  SHOW/TURBOCHANNEL

The following example is a sample display produced by the SHOW/TURBOCHANNEL command: 


TURBOCHANNEL: Device Name       Nexus Number        TC Slot

SHOW/UNIBUS (VAX Only)

On VAX systems, displays the addresses in UNIBUS I/O space that can be addressed.

Use of the SHOW/UNIBUS command requires the CMKRNL privilege.

Format

SHOW/UNIBUS

Parameters

None.

Qualifier

/ADAPTER=nexus

Specifies that the address of the specified UNIBUS adapter is to be displayed. The nexus value specifies the number of the UNIBUS adapter. It can be expressed as an integer or as one of the names listed by the SYSGEN command SHOW/ADAPTER.

Description

The SHOW/UNIBUS command reads all device registers. For some controllers, the result might be reading a character out of a buffer or some other undesired action. Therefore, use the SHOW/UNIBUS command only when you debug a UNIBUS configuration. On a system with more than one UNIBUS adapter, the command shows only the address of the first UNIBUS adapter.

Note
Never use the SHOW/UNIBUS command on a running system. Use of this command is valid only during a conversational bootstrap.

Example


SYSGEN>  SHOW/UNIBUS/ADAPTER=4

This command displays the available addresses for nexus 4, as follows: 


**UNIBUS map for nexus #4 on 30-JUN-2000  14:19:38.00 **

TERMINAL

Modifies the Ctrl/C, Ctrl/O, Ctrl/Y, and Ctrl/Z echo strings on a systemwide basis.

Format

TERMINAL/ECHO

Parameters

None.

Qualifiers

None.

Description

Before entering the TERMINAL command, edit the file SYSGTTSTR.MSG in SYS$EXAMPLES. The file contains detailed instructions for the editing procedure.

When you enter the TERMINAL command after editing the file, the modifications you have specified are carried out.

USE

Initializes the SYSGEN work area with system parameter values and the name of the site-independent startup command procedure, overwriting existing values. The initial values of the SYSGEN work area when the utility is invoked are the active values.

Specify the source for both the parameter values and the procedure name. They can be retrieved from a parameter file, the current system parameter file on disk, the active system in memory, or the default list.

Format

USE file-spec

Parameter

file-spec

The file specification of a system parameter file from which data is to be retrieved. You can use the SYSGEN command WRITE to create the parameter file. The default file type is .PAR.

In place of a file specification, you can specify one of the following keywords:

CURRENT

Specifies that source information is to be retrieved from the current system parameter file on disk.

On VAX systems, the system parameter file is SYS$SYSTEM:VAXVMSSYS.PAR.

On Alpha systems, the system parameter file is SYS$SYSTEM:ALPHAVMSSYS.PAR.

ACTIVE

Specifies that source information is to be retrieved from the active system in memory.

DEFAULT

Specifies that source information is to be retrieved from the default list. The USE DEFAULT command initializes the SYSGEN work area with parameter values that are built into SYSGEN; these values allow the operating system to boot on any standard configuration.

To avoid starting all layered products on a system that is not tuned for them, possibly causing the system to hang, set the STARTUP_P1 system parameter as follows: 


SYSGEN> SET STARTUP_P1 "MIN"

Qualifiers

None.

Examples

#1 

SYSGEN> USE SYS$SYSTEM:SPECIAL

This command uses the existing parameter file SYS$SYSTEM:SPECIAL.PAR.

#2 

SYSGEN> USE DEFAULT


SYSGEN> SET STARTUP_P1 "MIN"

The first command initializes the SYSGEN work area with default parameter values. The second command sets the STARTUP_P1 system parameter to "minimum."

WRITE

Writes the system parameter values and the name of the site-independent startup command procedure from the SYSGEN work area to a parameter file, the current system parameter file on disk, or the active system in memory.

Format

WRITE file-spec

Parameter

file-spec

The file specification of a new parameter file to be created. The default file type is .PAR.

In place of a file specification, you can specify one of the following keywords:

CURRENT

Specifies that source information is to be written to the current system parameter file on disk.

On VAX systems, the system parameter file is SYS$SYSTEM:VAXVMSSYS.PAR.

On Alpha systems, the system parameter file is SYS$SYSTEM:ALPHAVMSSYS.PAR.

Use of the WRITE CURRENT command requires the SYSPRV privilege.

ACTIVE

Specifies that source information is to be written to the active system in memory. (Only the dynamic parameter values are written to the active system.)

Use of the WRITE ACTIVE command requires the CMKRNL privilege.

Qualifiers

None.

Description

On VAX systems, the implementation of security auditing within SYSGEN has altered the reporting of modifications to the system parameter file VAXVMSSYS.PAR. System managers can receive notification of a change to the file by setting up an access control list (ACL) on the file to signal such an event, as in the following example: 


$ SET SECURITY/ACL=(ALARM=SECURITY,ACCESS=WRITE+FAILURE+SUCCESS)-
_$ SYS$SYSTEM:VAXVMSSYS.PAR

For more information about setting ACLs, refer to the OpenVMS User's Manual and the OpenVMS Guide to System Security.

On Alpha systems, both the WRITE ACTIVE and WRITE CURRENT commands send a message to OPCOM and log the event.

Examples

#1 

SYSGEN> WRITE SYS$SYSTEM:SPECIAL

This command creates a new parameter specification file, SYS$SYSTEM:SPECIAL.PAR.

#2 

SYSGEN> WRITE CURRENT

On VAX systems, this command modifies the current system parameter file on disk, VAXVMSSYS.PAR.

On Alpha systems, this command modifies the current system parameter file on disk, ALPHAVMSSYS.PAR.
