The INP Dump facility is used only by factory-level support
per-
sonnel.
It
dumps the contents of the INP memory for analyzing
the exact state of an INP in use.
Invoked by either an INP hard-
ware problem or an INP software problem, the
dump
data
can
be
returned to the factory either on magnetic tape or in the form of
a listing.
Dumping the INP and saving the data is done automatically by
the
system software.
As dumps are completed, the data is stored into
files named "INPLOGnn", where nn is a number not greater than the
maximum number of dump files for the system.
This limit
assures
that multiple INP dumps cannot adversely affect system storage.
Messages regarding INP dumps are directed to the system
console.
The initial message announces the dump and specifies which INP is
dumping:
INP BOARD FAILURE - LDEV xx
where xx is the logical device
number.
Notification
that
the
data
has
been saved and identification of the dump file appears
next:
!NP RAM DUMPED IN INPLOGnn
If the creation of this new INP dump
file
attains
the
maximum
number allowed, another message is generated:
STORE AND PURGE ALL INPLOGnn FILES
Any further INP dumps will not be saved until the
previous
dump
files are processed.
As previously mentioned, either of two media can be used for
re-
turning the INP dump data to the factory:
magnetic tape or list-
ing.
The more obvious method is to store the INPLOG files onto a
tape and send the tape to the factory.
The other alternative
is
to run the INP Dump Analyzer against each INPLOG file.
Each file
then generates
a
listing
of
approximately
50
pages.
These
listings
can
be
sent to the factory, thus eliminating the need
for shipping magnetic tapes.
The latter method requires only a few simple MPE
commands.
The
first
step
is
to
define
the
list file for the Analyzer.
By
default, the Analyzer will output to $STDLIST for
job
execution
or
to
a
device
class of LP for session execution.
If another
output device is desired, a file or device
equation
