In addition, an LSI command-line configuration program is available from http://www.ibm.com/servers/eserver/support/xseries/index.html/. Consider the following information when using the LSI Configuration Utility program to configure and manage arrays: v The integrated SAS/SATA controller with RAID capabilities supports the following features: - Integrated Mirroring (IM) with hot-spare support (also known as RAID 1) Use this option to create an integrated array of two disks plus an optional hot spare. All data on the primary disk can be migrated. - Integrated Mirroring Enhanced (IME) with hot-spare support (also known as RAID 1E) Use this option to create an integrated mirror enhanced array of three to eight disks, including an optional hot spare. - Integrated Striping (IS) (also known as RAID 0) Use this option to create an integrated striping array of two to eight disks. All data on the array disk will be deleted. 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 If you use an integrated SAS/SATA controller with RAID capabilities to configure a RAID 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 If you install a different type of RAID controller, see the documentation that comes with the controller for information about viewing and changing SAS settings for attached devices. To start the LSI Configuration Utility program, complete the following steps: 1. Turn on the server. 2. When the message > is displayed, 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. To change the settings of the selected items, follow the instructions on the screen. If you select Raid Properties, SAS Topology, or Advanced Adapter Properties, additional screens are displayed. See the User's Guide on the IBM System x Documentation CD for more information about the LSI Configuration Utility program. 46 System x3200 Type 4362 and 4363: Installation Guide

The

SAS/SATA
controller
with
RAID
capabilities
supports
the
following
features:
–
Integrated
Mirroring
(IM)
with
hot-spare
support
(also
known
as
RAID
1)
Use
this
option
to
create
an
integrated
array
of
two
disks
plus
an
optional
hot
spare.
All
data
on
the
primary
disk
can
be
migrated.
–
Integrated
Mirroring
Enhanced
(IME)
with
hot-spare
support
(also
known
as
RAID
1E)
Use
this
option
to
create
an
integrated
mirror
enhanced
array
of
three
to
eight
disks,
including
an
optional
hot
spare.
–
Integrated
Striping
(IS)
(also
known
as
RAID
0)
Use
this
option
to
create

All
data

Hard

drive
capacities
affect
how
you
create

treats
them
as
if
they
all
have
the
capacity
of
the
smallest
hard

If
you
use
an
integrated
SAS/SATA
controller
with
RAID
capabilities
to
configure
a
RAID
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
If
you
install
a
different
type
of
RAID
controller,
see
the
documentation
that
comes
with
the
controller
for
information
about
viewing
and
changing
SAS
