Make
sure
that
the
operating
system
that
you
plan
to
install
supports
IDE
RAID.
Operating
systems
that
support
IDE
RAID
on
your
server
type
are
listed
on
the
ServerProven
list
at
http://www.ibm.com/pc/compat/.
4.
Make
sure
that
two
IDE
hard
disk
drives
are
installed
in
the
blade
server
(see
the
“Installing
an
IDE
drive
option”
on
page
23
for
instructions).
Important:
To
avoid
potential
performance
and
reliability
problems
when
configuring
or
replacing
hard
disk
drives
in
a
mirrored
RAID
configuration,
make
sure
that
the
storage
capacities
and
speeds
of
the
hard
disk
drives
are
identical.
5.
Create
a
diskette
or
CD
containing
the
IDE
RAID
device
drivers
for
your
operating
system.
The
latest
IDE
RAID
device
drivers
for
supported
operating
systems
are
available
for
download
from
the
IBM

blade
server,
making
sure
that
you
install
the
correct
IDE
RAID
device
drivers
(see
Chapter
5,

for
supported
operating
systems
are
available
for
download
from

operating-system
setup;
make
sure
you
pay
attention
to
all
messages
that
are
displayed.
Use
care
when
