Step
4
Prepare
the
disks
for
migration.
Generating
the
metadata
for
each
disk
pair
rebuilds
the
indexes.
Therefore,
depending
on
the
data
size,
this
process
can
take
a
long
time
to
complete.
To
expedite
the
process,
you
can
launch
multiple
CLI
sessions
and
run
the
metadata
regeneration
command
in
each
session
to
complete
the
process
simultaneously
for
every
pair.
For
details,
see
.
1.
Insert
the
disks
into
the
new
Log
Collector.
For
details,
refer
to
the
disk
replacement
procedure
in
the
You
must
maintain
the
disk
pair
association.
Although
you
can
place
a
disk
pair
from
slot
A1/A2
on
the
old
appliance
into
slot
B1/B2
on
the
new
appliance,
you
must
keep
the
disks
together
in
the
same
slot;
otherwise,
Panorama
might
not
restore
the
data
successfully.
2.
Enable
the
disk
pairs
by
running
the
following
CLI
command
for
each
pair:
>
request
system
raid
add
<slot>
force
no
‐
format
For
example:
>
request
system
raid
add
A1
force
no
‐
format
>
request
system
raid
add
A2
force
no
‐
format
The
force
and
no-format
arguments
are
required.
The
force
argument
associates
the
disk
pair
with
the
new
Log
Collector.
The
no-format
argument
prevents
reformatting
of
the
drives
and
retains
the
logs
stored
on
the
disks.
3.
Generate
the
metadata
for
each
disk
pair.
>
request
metadata
‐
regenerate
slot
<slot_number>
For
example:
>
request
metadata
‐
regenerate
slot
1
You
can
ignore
any
unary operator expected
error
that
appears
after
entering
this
command.
Step
5
Migrate
the
logs.
You
must
use
the
Panorama
CLI
for
this
step,
not
the
web
interface.
You
must
assign
the
new
Log
Collector
to
the
Collector
Group
that
contains
the
old
Log
Collector.
1.
Assign
the
new
Log
Collector
to
the
Collector
Group
and
commit
your
changes
to
Panorama.
>
configure
#
set
log
‐
collector
‐
group
<collector_group_name>
logfwd
‐
setting
collectors
<new_LC_serial_number>
#
commit
#
exit
2.
For
each
disk
pair,
migrate
the
logs
from
the
old
Log
Collector
to
the
new
Log
Collector
and
attach
the
disk
pair
to
the
new
Log
Collector.
