Pointer
to
the
operating
system
not
found
in
non-volatile
storage.
Values
normally
found
in
non-volatile
storage
that
point
to
the
location
of
an
operating
system
were
not
found.
This
can
happen
for
two
reasons,
either
your
installed
operating
system
does
not
support
storing
the
values
or
some
event
occurred
that
caused
the
system
to
lose
non-volatile
storage
information
(drainage
or
replacement
of
the
battery).
If
you
are
running
AIX,
this
information
can
be
reconstructed
by
running
the
bootlist
command
specifying
the
device
that
the
operating
system
is
installed
on.
Refer
to
your
AIX
documentation
for
the
exact
syntax
and
usage
of
the
bootlist
command.
To
boot
the
operating
system
so
that
the
above-
mentioned
values
can
be
reconstructed,
power
off
the
system
and
power
it
on
again.
This
should
cause
the
system
to
look
for
the
operating
system
in
the
devices
contained
in
the
custom
boot
list
or
in
the
default
boot
list,
depending
on
the
condition
of
the
system.
If
this
is
not
successful,
use
the
System
Management
Services
Menus
to
modify
the
Boot
Sequence
(also
known
as
boot
list)
to
include
devices
that
are
known
to
contain
a
copy
of
the
operating
system.
For
example,
select
a
hard
disk
known
to
have
a
copy
of
the
operating
system
as
the
first
and
only
device
in
the
boot
sequence
(boot
list)
and
attempt
to
boot
again.
