Replacing
hot-swap
drives
Drive
problems
include
any
malfunctions
that
delay,
interrupt,
or
prevent
successful
I/O
activity
between
the
hosts
and
the
hard
disk
drives.
This
includes
transmission
problems
between
the
host
controllers,
the
RAID
controllers,
and
the
drives.
This
section
explains
how
to
replace
a
failed
drive.
Notes:
1.
Failure
to
replace
the
drives
in
their
correct
bays
might
result
in
loss
of
data.
If
you
are
replacing
a
drive
that
is
part
of
a
RAID
level
1
or
RAID
level
5
logical
drive,
ensure
that
you
install
the
replacement
drive
in
the
correct
bay.
2.
After
you
remove
a
drive
CRU,
wait
70
seconds
before
replacing
or
reseating
the
drive
CRU
to
allow
the
drive
to
properly
spin
down.
Failure
to
do
so
may
cause
undesired
events.
Use
the
following
procedure
to
replace
hot-swap
drives:
1.
Check
the
hardware
and
software
documentation
that
is
provided
with
the
system
to
see
if
there
are
restrictions
regarding
hard
disk
drive
configurations.
Some
system
fibre-channel
configurations
might
not
allow
mixing
different
drive
capacities
or
types
within
an
array.
2.
Check
the
Storage
Manager
client
online
help
for
recovery
procedures
for
a
drive
that
has
failed.
Follow
the
steps
in
the
software
procedure
before
you
continue
with
this
procedure.
3.
Determine
the
location
of
the
drive
that
you
want
to
remove.
Attention:
Never
hot-swap
a
drive
CRU
when
its
green
Activity
LED
is
flashing.
Hot-swap
a
drive
CRU
only
when
its
amber
Drive
fault
LED
is
on
and
not
flashing
or
when
the
drive
is
inactive
with
the
green
Activity
LED
on
and
not
flashing.
If
the
drive
is
not
in
a
failed
state
(as
indicated
by
a
lit
amber
LED),
manually
fail
the
drive
using
