Chapter 4. Installing the operating system

Before you install the operating system on the compute node, verify that the compute node is installed in
the IBM Flex System Enterprise Chassis, that the management-module firmware is at the latest available
level, and that the compute node is turned on.
About this task
If you are not using an unattended network-installation method to install your operating system, you
must first provide a serial over LAN (SOL) connection to the compute node to install your operating
system. For information about starting an SOL session, see http://publib.boulder.ibm.com/infocenter/
flexsys/information/topic/com.ibm.acc.cmm.doc/dw1kt_cmm_cli_book.pdf.
Important:
v After you install the operating system on the compute node, you must install any service packs or
update packages that come with the operating system. For additional information, see the instructions
that come with your operating-system documentation and the service packs or update packages.
v If you plan to install an Ethernet I/O expansion card, first install the operating system so that the
onboard ports can be recognized and configured before the ports on the I/O expansion card. If you
install the Ethernet I/O expansion card before you install the operating system, the I/O expansion card
ports will be assigned before the onboard ports.
See the ServerProven website for information about supported operating-system versions and all compute
node optional devices.

Locating the installation instructions

You can order the IBM Flex System p260 Compute Node or IBM Flex System p460 Compute Node with
Virtual I/O Server (VIOS), AIX operating-system, or IBM i operating-system already installed. If you did
not order your compute node with these operating systems installed, you can install them as a local
operating system. After installing VIOS, you can install the AIX, Linux, or IBM i operating system as a
client operating system in a logical partition (LPAR).
About this task
After you configure the compute node hardware, go to the operating-system documentation for the latest
operating-system installation instructions. See the following operating system descriptions for more
information:
v Installing Virtual I/O Server
See the Installing section of the PowerVM Information Roadmap.
If you did not order your servers with the VIOS software installed, you can use the Virtual I/O Server
DVD in the product package to install VIOS and set up a virtual environment that supports client
operating systems in logical partitions. You can then install any of the supported operating systems as
a client in an LPAR.
The order of installation of VIOS and the operating systems is important. You can update the firmware
first with the stand-alone Diagnostics CD, but you must install the VIOS software before you install any
other software. The VIOS software creates the Integrated Virtual Manager administrator console and the
first logical partition, which VIOS and Integrated Virtual Manager (IVM) occupy.
After you install VIOS, you can use the IVM and Micro-Partitioning
for client operating systems.
