VAX-tt/730
DIAGNOSTIC SYSTEM STRUCTURE
The
VAX-II
diagnostic
structure
consist
of
six program levels, as follows:
Level t - V
AX/VMS-based
Operating
system diagnostic program using logical or virtual
queue
I/O,
such as:
V
AX
System
Diagnostic (exerciser)
Level
2R
- Diagnostic supervisor-based diagnostic programs restricted to running under
VMS
only
using physical queue
I/O,
such as:
Certain
peripheral diagnostic programs
Level 2 - Diagnostic supervisor-based diagnostic programs
that
can be run either under
VAX/VMS
(on-line)
or
in the standalone mode using physical queue
I/O,
such as:
Formatter
and
reliability level peripheral diagnostic programs
Level 3 - Diagnostic supervisor-based diagnostic programs
that
can be run in standalone mode only
using physical queue
I/O,
such as:
Functional level peripheral diagnostic programs
Repair level peripheral diagnostic programs
CPU
cluster diagnostic programs
Level 4 - Standalone macrodiagnostic programs
that
run without
the
supervisor, such as:
Hard-core instruction set
Level 5 - Console-based diagnostic programs
that
can be run in
the
standalone mode only, such as:
Microdiagnostics
Microdiagnostic monitors
Console diagnostics
Overlapping four levels (levels 5, 4, 3,
and
2)
of
the
diagnostic system
structure
is
the
Customer
Runnable
Diagnostic (CRD).
CRD
is
a special
program
which simplifies the execution
of
these diagnostics with a
single command.
Refer
to
Chapter
7 for
further
information on
CRD.
Most diagnostic programs which test peripheral devices are not processor-specific.
They
run on the V
AX-
I 1/730 processor as well as
other
V
AX
processors. These programs are called transportable diagnostics.
They
are identified by
the
letter V as
the
second
character
of
the five-character program (e.g.,
EVREA).
Of
the diagnostic programs which test a V
AX-II
/730
system, some
are
transportable
and
some
are
processor-specific. V
AX-II
/730
processor-specific diagnostic programs
are
identified by the letter N as
the second
character
of
the
five-character program code (e.g.,
ENSAA).
See the V
AX
Diagnostic Index,
EVNDX,
for a complete list
of
VAX
diagnostic programs.
Refer
to
the
appropriate
program
documentation file to answer questions concerning the use
of
any
specific diagnostic
program.
