The
second
example
is
similar
to
example
1.
The
mklvcopy
command
starts
mirroring
the
infxlv
logical
volume.
#
mklvcopy
-e
m
-s
y
-k
infxlv
2
hdisk4
hdisk10
.
.
.
#
rmlvcopy
infxlv
1
hdisk4
In
this
example,
hdisk4
is
where
the
data
for
infxlv
already
exists,
and
hdisk10
is
where
the
mirror
copy
resides.
It
is
also
where
you
want
to
ultimately
move
the
data.
Using
the
migratepv
command
Use
the
following
information
as
a
guide
for
how
to
use
the
logical
volume
manager
(LVM)
migratepv
command
to
migrate
data
that
is
associated
with
physical
volumes.
You
can
use
the
LVM
migratepv
command
to
migrate
data
that
is
associated
with
physical
volumes.
The
following
examples
show
how
to
use
the
migratepv
command.
#
migratepv
hdisk1
hdisk2
#
migratepv
-l
datalv
hdisk3
hdisk9
In
the
example,
all
data
migrates
from
hdisk1
to
hdisk2
.
The
migratepv
command
updates
all
LVM
references.
From
the
time
that
the
command
completes,
the
LVM
no
longer
uses
hdisk1
to
access
data
that
was
previously
stored
there.
As
the
data
is
physically
moved,
the
target
physical
volume
must
have
enough
spare
physical
volumes
to
accommodate
data
from
the
source
physical
volumes.
After
this
command
completes,
you
can
remove
the
source-physical
volume
from
the
volume
group.
To
avoid
disrupting
users,
use
the
migratepv
command
while
the
system
is
active.
The
migratepv
command
migrates
data
by
performing
the
following
actions:
v
Creating
a
mirror
of
the
logical
volumes
that
you
are
moving
v
Synchronizing
the
logical
volumes
v
Removing
the
original
logical
volume
You
can
use
the
migratepv
command
to
move
data
from
one
physical
volume
to
another
physical
volume
within
the
same
volume
group.
The
following
usage
parameters
apply
to
this
command:
migratepv
[-i]
[-l
LVname]
SourcePV
DestinationPV...
Note:
You
can
specify
more
than
one
destination
physical
volume.
First,
identify
the
source
disk
from
which
you
want
to
migrate
the
data.
Then,
identify
the
target
disk
to
which
you
want
to
migrate
the
data.
You
can
only
migrate
to
disks
that
are
already
in
the
rootvg
volume
group.
To
get
a
list
of
disks
that
are
