Using ServeRAID Manager Use the ServeRAID Manager program to: v Configure arrays v View the RAID configuration and associated devices v Monitor operation of the RAID controllers To perform some tasks, you can run ServeRAID Manager as an installed program. However, to configure the SCSI controller and perform an initial RAID configuration on your server, you must run ServeRAID Manager in a Startable-CD mode, as described in the instructions in this section. If you install a RAID adapter in your server, use the configuration method described in the instructions that come with the adapter to view or change SCSI settings for attached devices. See the ServeRAID documentation on the IBM ServeRAID Support CD or additional information about RAID technology and instructions for using ServeRAID Manager to configure your SCSI controller. Additional information about ServeRAID Manager is also available from the Help menu. For information about a specific object in the ServeRAID Manager tree, select the object and click Actions → Hints and tips. Configuring the controller By running ServeRAID Manager in Startable CD mode, you can configure the controller before you install your operating system. The information in this section assumes that you are running ServeRAID Manager in Startable CD mode. To run the ServeRAID Manager program in startable-CD mode, turn on the server; then, insert the IBM ServeRAID Support CD into the CD-ROM drive. If the ServeRAID Manager program detects an unconfigured controller and ready drives, the program automatically starts the Configuration wizard. In the Configuration wizard, you can select Express configuration or Custom configuration. Express configuration automatically configures the controller by grouping the first two physical drives in the ServeRAID Manager tree into an array and creating a RAID level-1 logical drive. If you select custom configuration, you can select the two physical drives that you want to group into an array and create a hot-spare drive. Using express configuration Complete the following steps to use Express configuration: 1. In the ServeRAID Manager tree, click the controller that you want to configure. 2. From the toolbar, click Create. 3. Click Express configuration. 4. Click Next. The "Configuration summary" window opens. 5. Review the information that is displayed in the "Configuration summary" window. To change the configuration, click Modify arrays or Modify logical drives. Note: Some operating systems have size limitations for logical drives. Before you save the configuration, verify that the size of the logical drive is appropriate for your operating system. 6. Click Apply; then, click Yes when asked if you want to apply the new configuration. The configuration is saved in the controller and in the physical drives. Chapter 4. Configuring the server 53

Manager
program
to:
v
Configure

configuration
and
associated
devices
v
Monitor
operation
of
the

To
perform
some
tasks,
you
can
run
ServeRAID
Manager
as
an
installed
program.
However,
to
configure
the
SCSI
controller
and
perform
an

RAID
configuration
on
your
server,
you
must
run
ServeRAID
Manager
in
a
Startable-CD
mode,
as
described
in
the
instructions
in
this
section.
If
you
install
a
RAID
adapter
in
your
server,
use
the
configuration
method
described
in
the
instructions
that
come
with
the
adapter
to
view
or
change
SCSI
settings
for
attached
devices.
See
the
ServeRAID
documentation
on
the
IBM
ServeRAID
Support
CD
or
additional
information
about
RAID
technology
and
instructions
for
using
ServeRAID
Manager
to
configure
your
SCSI
controller.
Additional
information
about
ServeRAID
Manager
is
also
available
from

Configuring
the
controller
By
running
ServeRAID
Manager
in
Startable
CD
mode,
you
can
configure
the
controller
before
you
install
your
operating
system.
The
information
in
this
section
assumes
that
you
are
running
ServeRAID
Manager
in
Startable
CD
mode.
To
run
the
ServeRAID
Manager
program
in
startable-CD
mode,
turn
on
the
server;
then,
insert
the
IBM
ServeRAID
Support
CD
into
the
CD-ROM
drive.
If
the
ServeRAID
Manager
program
detects
an
unconfigured
controller
and
ready
drives,
the
program
automatically
starts
the
Configuration
wizard.
In
the
Configuration
wizard,
you
can
select
Express
configuration
or
Custom
configuration
.
Express
configuration
automatically
configures
the
controller
by
grouping
the
first
two
physical
drives
in
the
ServeRAID
Manager
tree
into
an
array
and
creating
a
RAID
level-1
logical
drive.
If
you
select
custom
configuration,
you
can
select
the
two
physical
drives
that
you
want
to
group
into
an
array
and
create
a
hot-spare
drive.
Using
express
configuration
Complete
the
following
steps
to
use
Express
configuration:
1.
In
the
ServeRAID
Manager
tree,
click

logical
drives
.
Note:
Some
operating
systems
have
size
limitations
for
logical
drives.
Before
you
save
the
configuration,
verify
that
the
size
of
the
logical
drive
is
appropriate
for
your
operating
system.
