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  –  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.
