If
all efforts
to
do a
TC
fail, you probably will have
to
do a
Hard
Reset. Perform a
hard
reset by entering
RS
at
the
CM
>
prompt.
If
you do a reset, do
not
waste your time taking a memory dump. Instead,
just
bring
the
machine up
and
report
the
problem
to
the
Response Center.
Caution
I
Do
not
do a
hard
reset (RS) unless absolutely necessary. A
hard
reset
invalidates
the
memory dump
and
destroys
important
troubleshooting
information.
Step
2:
Boot
to
ISL.
At this
point,
you have successfully
initiated
a
TC
and
are watching
the
hex display change
through
all
of
its
selftest codes.
1.
After a
TC,
the
console is automatically placed
into
console mode so you can
monitor
the
boot
process messages.
2.
When
the
console displays a
prompt
for booting
the
computer, enter a response so
that
the
computer
boots from
the
PRIMARY
PATH-
as you would for any normal system
start
attempt.
3.
If
the
autoboot
flag is enabled, you see:
Processor
is
starting
the
autoboot
process.
To
discontinue,
press
any key
within
10
seconds
...
As soon as you see
the
above
prompt,
press a key.
Caution
I
Note
•
Autoboot
is a script
of
ISL commands
that
are automatically executed.
If your site uses
the
Autoboot
feature, make sure
that
you
abort
the
autoboot
sequence! Otherwise
the
memory
dump
will be lost unless
the
autoboot
file
contains a
DUMP
command.
If you find
that
you do
not
get this console
prompt,
but
instead
seem
to
be
hanging
at
the
xxxx, 9001, or C640 code,
try
typing
CO
at
the
CM
>
prompt
.
This should switch you
into
Console Mode and,
if
autoboot
is
not
enabled or
if
the
10
second
autoboot
sequence has
not
expired, you should be able
to
boot
to
ISL.
Step
3:
Dump
the System.
At
this
point,
you are
at
the
ISL >
prompt.
1.
Install
a
tape
on
the
tape
drive configured as
the
"Alternate
Path"
device
(the
tape
drive
from which you normally
UPDATE
or
INSTALL).
2.
Put
the
drive online
and
ensure
that
the
tape
loaded properly.
