In
addition,
an
LSI
command-line
configuration
program
(CFG1030)
and
the
utility
that
performs
a
low-level
format
on
a
SCSI
hard
disk
drive
are
available
from
http://www.ibm.com/pc/support/.
Consider
the
following
information
when
using
the
LSI
Logic
setup
utility
program
and
ServeRAID
Manager
to
configure
and
manage
arrays:
v
The
integrated
SCSI
controller
with
RAID
capabilities
in
the
server
supports
only
RAID
level
1
and
1E;
using
a
hard
disk
drive
as
a
hot-spare
is
optional.
Installing
an
optional
ServeRAID
controller
provides
additional
RAID
levels.
Notes:
1.
RAID
level
1
with
two
drives
provides
data
mirroring,
which
provides
a
redundant
copy
of
the
data.
2.
RAID
level
1
with
three
to
four
drives
allows
data
mirroring
with
a
hot-spare
drive.
v
When
you
create
a
RAID
level-1
(mirrored)
pair,
all
drives
must
be
on
the
same
channel.
v
Hard
disk
drive
capacities
affect
how
you
create
arrays.
The
drives
in
an
array
can
have
different
capacities,
but
the
RAID
controller
treats
them
as
if
they
all
have
the
capacity
of
the
smallest
hard
disk
drive.
v
To
help
ensure
signal
quality,
do
not
use
drives
with
different
speeds
and
data
rates
in
the
array.
v
You
can
set
up
a
mirror
after
the
operating
system
is
installed
on
the
primary
drive
only
if
you
are
using
an
integrated
SCSI
controller
with
RAID
capabilities.
If
you
want
to
use
the
RAID
capabilities,
make
sure
that
the
primary
drive
has
the
lower
SCSI
ID
(for
example,
0).
Important:
If
you
use
an
integrated
SCSI
controller
with
RAID
capabilities
to
configure
a
RAID
level-1
(mirrored)
array
after
you
have
installed
the
operating
system,
you
will
lose
access
to
any
data
or
applications
that
were
previously
stored
on
the
secondary
drive
of
the
mirrored
pair.
v
To
update
the
firmware
and
BIOS
codes
for
an
optional
ServeRAID
controller,
you
must
use
the
IBM
ServeRAID
Support
CD
that
comes
with
the
controller.
v
If
you
install
a
different
type
of
RAID
controller,
see
the
documentation
that
comes
with
the
controller
for
information
about
viewing
and
changing
SCSI
settings
for
attached
devices.
Using
the
LSI
Logic
setup
utility
program
Complete
the
following
steps
to
start
the
LSI
Logic
setup
utility
program:
1.
Turn
on
the
server
and
watch
the
monitor
screen.
2.
When
the
message
<<<
Press
<CTRL><C>
to
start
LSI
Logic
setup
utility
>>>
appears,
press
Ctrl+C.
If
an
administrator
password
has
been
set,
you
are
prompted
to
type
the
password.
3.
Use
the
arrow
keys
to
select
a
controller
(channel)
from
the
list
of
adapters;
then,
press
Enter.
4.
Follow
the
instructions
on
the
screen
to
change
the
settings
of
the
selected
items;
then,
press
Enter.
If
you
select
Device
Properties
or
Mirroring
Properties
,
additional
screens
are
displayed.
See
the
User’s
Guide
on
the
IBM
