1 – BUS
This command is for use on Alpha and Integrity servers only. It
lists all the buses, node numbers, bus names, TR numbers, and
base CSR addresses on the system. This display exists primarily
for internal engineering support.
On VAX systems, use the SYSGEN command SHOW/BUS.
1.1 – Description
The SYSMAN IO SHOW BUS command lists all the buses, node numbers,
bus names, TR numbers, and base CSR addresses. This display
exists primarily for internal engineering support. You must have
CMKRNL privilege to use SYSMAN IO SHOW BUS.

This example is from a DEC 7000 Model 600. Displays vary among
different Alpha and Integrity servers.
The indentation levels are deliberate in this display. They
indicate the hierarchy of the adapter control blocks in the
system. The column titles in the display have the following
meanings:
Column Titles Meaning
Bus Identity of the bus
Node Index into the associated bus array; the bus
slot
TR# Nexus number of the adapter to which the
specified device is connected
Name Name of the device
Base CSR Base CSR address of the device
On Alpha and Integrity servers, you can use the SDA command
CLUE CONFIG to display additional information including hardware
adapters and devices. This command is documented in the OpenVMS
Alpha System Dump Analyzer Utility Manual.
For more information about loading and configuing device drivers,
see Writing OpenVMS Alpha Device Drivers in C.
2 – DEVICE
This command is for use on Alpha and Integrity servers only.
It displays information about device drivers loaded into the
system, the devices connected to them, and their I/O databases.
All addresses are in hexadecimal and are virtual.
On VAX systems, use the SYSGEN command SHOW/DEVICE.
Format
IO SHOW DEVICE
2.1 – Description
The SYSMAN IO SHOW DEVICE command displays information about the
device drivers loaded into the system, the devices connected to
them, and their I/O databases.
The SYSMAN IO SHOW DEVICE command specifies that the following
information be displayed about the specified device driver:
Driver Name of the driver
Dev Name of each device connected to the driver
DDB Address of the device's device data block
CRB Address of the device's channel request block
IDB Address of the device's interrupt dispatch block
Unit Number of each unit on the device
UCB Address of each unit's unit control block
All addresses are in hexadecimal and are virtual.
For additional information about SYSMAN, see A Comparison of
System Management on OpenVMS AXP and OpenVMS VAX (archived) but
available on the OpenVMS Documentation CD-ROM) and the VSI OpenVMS
System Manager's Manual.
2.2 – Example

SYS$TTDRIVER, OPERATOR, and NLDRIVER do not have devices
associated with them.
3 – EXCLUDE
This command is for use on Alpha and Integrity servers
only. It displays the permanent exclusion list used in the
autoconfiguration of devices.
Format
IO SHOW EXCLUDE
3.1 – Description
The SYSMAN IO SHOW EXCLUDE command displays the permanent
exclusion list on the console. This list is used in the
autoconfiguration of devices.
3.2 – Example
SYSMAN> IO SHOW EXCLUDE
%SYSMAN-I-
IOEXCLUDE, the current permanent exclusion list is: DKC500,DKD*
This example shows the permanent exclusion list used in the
autoconfiguration of devices; the current list contains DKC500
and all DKD devices.
4 – PREFIX
This command is for use on Alpha and Integrity servers only. It
displays the current prefix list used in the manufacture of ICBM
names.
Format
IO SHOW PREFIX
4.1 – Description
The SYSMAN IO SHOW PREFIX command displays the current prefix
list on the console. This list is used by the SYSMAN IO
AUTOCONFIGURE command to build ICBM names.
4.2 – Example
SYSMAN> IO SHOW PREFIX
%SYSMAN-I-IOPREFIX, the current prefix list is: SYS$,PSI$,VME_
This example shows the prefixes used by SYSMAN IO AUTOCONFIGURE
to build ICBM names.
