and

then

turn

off

the

storage

server.

After

replacing

all

the

drives,

you

must

reconfigure

the

new

drives

and

restore

data

from

backup.

See

the

procedure

in

This

is

the

safest

way

to

exchange

drives

without

losing

data.

However,

this

method

might

take

to

complete

because

of

the

backup,

reconfiguration,

and

restoration

processes.
