Checkpoints
enable
users
and
service
personnel
to
know
what
the
server
is
doing,
with
some
detail,
as
it
initializes.
These
checkpoints
are
not
intended
to
be
error
indicators,
but
in
some
cases
a
server
could
hang
at
one
of
the
checkpoints
without
displaying
an
8-character
error
code.
It
is
for
these
hang
conditions,
only,
that
any
action
should
be
taken
with
respect
to
checkpoints.
The
most
appropriate
action
is
included
with
each
checkpoint.
Before
taking
actions
listed
with
a
checkpoint,
check
for
additional
