When analyzing a dump, displays information about the state of a
    CPU at the time of the system failure.

    SHOW CPU is only valid when you are analyzing a crash dump. It
    is not a valid command when you are analyzing the running system,
    because all the CPU-specific information may not be available.
    If invoked when you are analyzing a running system, SHOW CPU will
    only list the CPU database address(es) for the specified CPU or
    all CPUs.

    Format

      SHOW CPU  [cpu-id | /FIRST | /NEXT | /PRIMARY]

1  –  Parameter

 cpu-id

    Numeric value indicating the identity of the CPU for which
    context information is to be displayed. If you specify the cpu-
    id parameter, the SHOW CPU command performs an implicit SET CPU
    command, making the CPU indicated by cpu-id the current CPU for
    subsequent SDA commands.

    If you do not specify a cpu-id, the state of the SDA current CPU
    is displayed.

    If you specify the cpu-id of a CPU that was not active at the
    time of the system failure, SDA displays the following message:

    %SDA-E-CPUNOTVLD, CPU not booted or CPU number out of range

    Type HELP SET CPU command and HELP CPU_CONTEXT for information
    on how this can affect the CPU context (and process context) in
    which SDA commands execute.

2  –  Qualifiers

2.1    /FIRST

     The state of the lowest numbered CPU (not necessarily the
     primary CPU) is displayed.

2.2    /NEXT

    The state of the next higher numbered CPU is displayed.
    SDA skips CPUs not in the configuration at the time of
    the system failure. If there are no further CPUs,
    SDA returns an error.

2.3    /PRIMARY

    The state of the primary CPU is displayed.
