For
the
example
above,
the
following
considerations
can
apply:
v
Assume
that
you
made
a
file
system
on
the
/dev/lv00
logical
volume.
AIX
LVM
uses
this
file
system
to
view
part
or
all
the
virtual
disks
that
the
storage
unit
has
made
available
to
the
system.
v
Mount
the
logical
volume
on
a
temporary
mount
point,
in
this
case
/mnt
.
v
Change
directories
to
the
directory
at
the
top
of
the
file
system
that
you
want
to
move
(
cd/data
).
v
Use
the
find
command
to
produce
a
list
of
file
names,
which
a
pipe
(|)
passes
to
the
cpio
command.
v
Unmount
both
file
systems
and
mount
the
new
file
system
over
the
original
mount
point
directory
when
the
migration
is
complete.
You
will
probably
be
unable
to
use
the
volume
management
methods
if
the
database
uses
volume
serial
numbers
in
its
licensing
code
or
validity
checking.
If
the
database
uses
licensing
methods
or
validity
checking,
you
might
be
able
to
only
export
the
database
from
its
old
locations
or
import
the
database
to
its
new
location.
The
database
software
provides
the
mechanism
to
move
the
data.
This
can
take
the
form
of
a
standard
database
backup
and
restore
if
it
does
not
have
any
specific
tools
for
moving
data.
Using
backup
and
restore
methods
to
migrate
data
Use
the
following
information
as
a
guide
for
how
to
use
the
backup
and
restore
methods
to
migrate
data.
In
some
cases,
the
only
method
that
is
available
to
transfer
data
is
to
back
it
up
to
tape
and
then
restore
it
to
the
new
disk.
This
method
is
slower
because
tape
devices
require
that
you
move
the
data
twice.
However,
if
you
are
removing
disks
before
you
install
the
DS8000,
the
only
way
to
move
the
data
is
with
a
tape
device.
You
can
find
a
number
of
different
archive
utilities
on
UNIX
systems.
The
cpio
command
can
also
create
and
read
archives
on
tape
devices.
Use
the
-o
(output)
option
to
create
archives,
and
use
the
-i
(input)
option
to
read
and
extract
data
from
archives.
AIX
provides
a
pair
of
commands:
backup
and
restore
.
The
backup
command
has
two
different
methods
of
creating
archives,
either
by
file
name
or
by
the
i-node.
Use
the
restore
command
to
read
any
archive
that
is
created
by
the
backup
command.
Solaris
and
HP-UX
provide
the
dump
and
restore
commands,
which
backup
and
restore
data
by
the
i-node.
The
tar
command
is
available
on
all
UNIX
systems
that
support
the
DS8000
and
is
another
way
to
create
and
extract
tape
archives.
Use
the
c
option
to
create
archives.
Use
the
x
option
to
extract
files
from
archives.
