paired
with
a
target
volume.
b.
If

method,
you
can
select
target
volumes
from
different
LSSs
on

a.
Select
the
Perform
initial
copy
option
the
first
time
a
that
volume
pair
is
created
because
it
is
needed
to
ensure
that
the
entire
source
volume
is
copied
to
the
target
volume
to
guarantee
that
the
source
and
target
volumes
contain
the
same
data.
b.
Optionally,
you
can
select
the
Suspend
Metro
Mirror
relationship
after
initial
copy
option
because
it
only
applies
to
Metro
Mirror
volume
pairs.
This
means
that
after
data
is
completely
copied
to
the
target
volume
of
the
volume
pair,
the
target
volume
goes
into
the
suspended
state.
12.
On
the
Verification
page,
review

FlashCopy
The
FlashCopy
function
enables
you
to
make
point-in-time,
full
volume
copies
of
data,
with
the
copies
immediately
available
for
read
or
write
access.
You
can
use
the
copy
with
standard
backup
tools
that
are
available
in
your
environment
to
create
backup
copies
on
tape.
FlashCopy
creates
a
copy
of
a
source
volume
on
the
target
volume.
This
copy
is
called
a
point-in-time
copy.
When
you
initiate
a
FlashCopy
operation,
a
FlashCopy
relationship
is
created
between
a
source
volume
and
target
volume.
A
FlashCopy
relationship
is
a
″
mapping
″
of
the
FlashCopy
source
volume
and
a
FlashCopy
target
volume.
This
mapping
allows
a
point-in-time
copy
of
that
source
volume
to
be
copied
to
the
associated
target
volume.
The
FlashCopy
relationship
exists
between
this
volume
pair
from
the
time
that
you
initiate
a
FlashCopy
operation
until
the
storage
unit
copies
all
data
from
the
source
volume
to
the
target
volume
or
you
delete
the
FlashCopy
relationship,
if
it
is
a
persistent
FlashCopy.
The
benefits
of
FlashCopy
are
that
the
point-in-time
copy
is
immediately
available
for
use
for
backups
and
that
the
source
volume
is
immediately
released
so
that
applications
can
be
restarted,
with
minimal
application
downtime.
The
target
volume
is
available
for
read
and
write
processing
so
it
can
be
used
for
testing
or
backup
purposes.
When
the
data
is
physically
copied,
a
background
process
copies
tracks
from
the
source
volume
to
the
target
volume.
The
amount
of
time
that
it
takes
to
complete
the
background
copy
depends
on
the
following
criteria:
v
The
amount
of
data
being
copied
v
The
number
of
background
copy
processes
that
are
occurring
