Chapter 6. Installing the operating system BladeCenter QS21 supports the following operating systems: v Red Hat Enterprise Linux 5.1 v Red Hat Enterprise Linux 5.2 If you download Linux distributions, ensure that you download the version compatible with Cell/B.E. Fedora (Fedora 7 and later) can be installed and supported from the Open Source only. You can view the current support levels in the Information Center topic Specified operating environments for Cell Broadband Engine solution. For general information on installing Linux, see the installation instructions that come with the distribution or are available at http://www.redhat.com/. For additional instructions specific to your blade server, check for QS21 documentation on the BladeCenter support Web site at http://www.ibm.com/ systems/bladecenter/support/. If you need to install Linux on numerous blade servers, consider using DIM (Distributed Image Management for Linux Clusters). DIM is a sophisticated cluster management system especially for large and very large number of nodes. For more information on DIM see http://www.alphaworks.ibm.com/tech/dim/. Note: IBM may add support for later versions of the operating systems or other operating systems. You can check the IBM support Web site or the Information Center topic Specified operating environments for Cell Broadband Engine solution to see the currently supported operating systems and levels. Preparing a boot device BladeCenter QS21 does not come with any onboard hard disks or other storage. Instead, you must allocate storage to BladeCenter QS21 as a resource. You can allocate: v Networked storage v SAS attached storage Note: A remote SAS storage must boot before BladeCenter QS21 attempts to boot the operating system from it. Using a boot device on the network You cannot directly install Linux on a network device attached to BladeCenter QS21. First you need to create an initial installation on a 64-bit POWER™ based system with local storage. You can then create multiple copies of the root file system on an NFS server. To be able to boot a particular blade server from a copy, adapt the instance specifics to the blade server and export the adapted copy for NFS mounting. Figure 27 on page 54 illustrates the main steps for creating a network installation that BladeCenter QS21 can boot from. © Copyright IBM Corp. 2006, 2008 53

Installing
the
operating
system
BladeCenter
QS21
supports
the
following
operating
systems:
v
Red
Hat
Enterprise
Linux
5.1
v
Red
Hat
Enterprise
Linux
5.2
If
you
download
Linux
distributions,
ensure
that
you
download
the
version
compatible
with
Cell/B.E.
Fedora
(Fedora
7
and
later)
can
be
installed
and
supported
from
the
Open
Source
only.
You
can
view
the
current
support
levels
in
the
Information
Center
topic
Specified
operating
environments
for
Cell
Broadband
Engine
solution.
For
general
information
on
installing
Linux,
see
the
installation
instructions
that
come
with
the
distribution
or
are
available
at
For
additional
instructions
specific
to
your
blade
server,
check
for
QS21
documentation
on
the
BladeCenter
support
Web
site
at
systems/bladecenter/support/.
If
you
need
to
install
Linux
on
numerous
blade
servers,
consider
using
DIM
(Distributed
Image
Management
for
Linux
Clusters).
DIM
is
a
sophisticated
cluster
management
system
especially
for
large
and
very
large
number
of
nodes.
For

Note:
IBM
may
add
support
for
later
versions
of
the
operating
systems
or
other
operating
systems.
You
can
check
the
IBM
support
Web
site
or
the
Information
Center
topic
Specified
operating
environments
for
Cell
Broadband
Engine
solution
to

supported
operating
systems
and
levels.
Preparing
a
boot
device
BladeCenter
QS21
does
not
come
with
any
onboard
hard
disks
or
other
storage.
Instead,
you
must
allocate
storage
to
BladeCenter
QS21
as
a
resource.
You
can
allocate:
v
Networked
storage
v
SAS
attached
storage
Note:
A
remote
SAS
storage
must
boot
before
BladeCenter
QS21
attempts
to
boot
the
operating
system
from
it.
Using
a
boot
device
on
the
network
You
cannot
directly
install
Linux
on
a
network
device
attached
to
BladeCenter
QS21.
First
you
need
to
create
an
initial
installation
on
a
64-bit
POWER
™
based
system
with
local
storage.
You
can
then
create
multiple
copies
of
the
root
file
system
on
an
NFS
server.
To
be
able
to
boot
a
particular
blade
server
from
a
copy,
adapt
the
instance
specifics
to
the
blade
server
and
export
the
adapted
copy
for
NFS
mounting.
Figure
27
on
page
54
illustrates
the
main
steps
for
creating
a
network
installation
that
BladeCenter
QS21
can
boot
from.
