AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
About This Book
This book describes different ways to install the AIX 5L Version 5.2 operating system in a partitioned
environment, including using a CD-ROM device to install AIX, the Network Installation Management (NIM)
interface, and alternate disk installation.
Before continuing, ensure that the service representative has completed the following tasks:
v Installation of all hardware components of the IBM eServer pSeries managed system
v Configuration of the Hardware Management Console (HMC)
If either of these processes has not been completed, contact your service representative.
To learn more about the planning issues associated with creating logical partitions, see the IBM Hardware
Management Console for pSeries Installation and Operations Guide for information on the following tasks:
v Preparing for Logical Partitioning
v Partition Management
v Logical Partitioning Mode Tasks
For more information on IBM eServer pSeries systems and the AIX operating system, refer to the IBM
eServer pSeries Information Center at the following URL:
http://publib16.boulder.ibm.com/pseries/en_US/infocenter/base
Who Should Use This Book
This guide is for system administrators who manage the installation, configuration, and maintenance of
one or more logical partitions that run the AIX operating system. Readers should be familiar with the
installation concepts, understand AIX system administration, and know how to manage a network
environment.
Highlighting
The following highlighting conventions are used in this book:
Bold
Italics
Monospace
Identifies commands, subroutines, keywords, files, structures, directories, and other items
whose names are predefined by the system. Also identifies graphical objects such as buttons,
labels, and icons that the user selects.
Identifies parameters whose actual names or values are to be supplied by the user.
Identifies examples of specific data values, examples of text similar to what you might see
displayed, examples of portions of program code similar to what you might write as a
programmer, messages from the system, or information you should actually type.
Case-Sensitivity in AIX
Everything in the AIX operating system is case-sensitive, which means that it distinguishes between
uppercase and lowercase letters. For example, you can use the ls command to list files. If you type LS, the
system responds that the command is ″not found.″ Likewise, FILEA, FiLea, and filea are three distinct file
names, even if they reside in the same directory. To avoid causing undesirable actions to be performed,
always ensure that you use the correct case.

Configuring Online Documentation
It is not necessary to install the operating system’s online documentation onto your server. You can access
all of the documentation through the Internet at the following Web address:
http://publib16.boulder.ibm.com/pseries/en_US/infocenter/base
However, if you use the Documentation Library Service to search any online documentation, it searches
only the registered documentation that is installed on your documentation server.
To view the online documentation, you must have an HTML browser installed on your system. The
Netscape Communicator browser is located on the AIX 5L Expansion Pack. You can install the Netscape
Communicator browser by installing the Netscape bundle in the SMIT Install Software Bundle menu
(smitty install_bundle).
Installing the Online Documentation on a System
1. Insert the AIX Documentation CD in the CD device.
2. Type smitty install_latest.
3. Select or type the CD device containing the AIX Documentation CD in the field provided and press
Enter.
4. In the Install Software menu, use the F4 key to list the documentation packages and filesets that are
available to install. Select a package or fileset by highlighting the appropriate choice and pressing F7.
Press Enter when you have finished making your selections.
5. Select the appropriate responses for the remaining questions in the Install Software menu or accept
the default choices. When you are done, press Enter. From the confirmation menu, press Enter to
install the software.
6. Press F10 (or Esc+0) to exit the SMIT menu and return to the command line.

AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
Chapter 2. Overview of Partitioning
Partitioning your system is similar to partitioning a hard drive. When you partition a hard drive, you divide a
single physical hard drive so that the operating system recognizes it as a number of separate logical hard
drives. You have the option of dividing the system’s resources by using the Hardware Management
Console (HMC) to partition your system. On each of these divisions, called partitions, you can install an
operating system and use each partition as you would a separate physical system.
Managed System
A managed system is a system that is physically attached to and managed by the HMC. The HMC can
perform tasks that affect the entire managed system, such as powering the system on and off. You can
also create partitions and partition profiles within each managed system. These partitions and partition
profiles define the way that you configure and operate your partitioned system.
Logical Partitions
A logical partition (LPAR) is the division of a computer’s processors, memory, and hardware resources into
multiple environments so that each environment can be operated independently with its own operating
system and applications. The number of logical partitions that can be created depends on the system’s
processor model and resources available. Typically, partitions are used for different purposes, such as
database operation, client/server operations, Web server operations, test environments, and production
environments. Each partition can communicate with the other partitions as if each partition is a separate
machine.
Beginning with AIX 5.1, the AIX operating system supports partitioned environments. Although the AIX
installation concepts are the same, the ability to configure and manage a partitioned environment with the
AIX operating system is available in AIX 5.2. This guide assumes the reader has some familiarity with
partition management. For more information about partition management, refer to the IBM Hardware
Management Console for pSeries Installation and Operations Guide, order number SA38-0590.
A logical partition must contain a minimum set of resources, as follows:
v 1 GB of available system memory
v
v
v
v
One available system processor
One boot device on an assigned I/O slot
One available network adapter (for error reporting)
Any other adapters you may need on an assigned I/O slot
Processors, memory, and I/O slots can be allocated to any partition, regardless of their location. However,
if you attempt to activate a partition, but the resources you specified are not available at the time, partition
activation fails. It is important to keep track of your system’s resources to avoid activation failures. PCI
slots are assigned individually to partitions, and memory can be allocated in 256 MB increments. The
granularity of the resources that can be assigned to partitions is very fine, providing flexibility to create
systems with just the desired amount of resources. Each partition runs its own copy of the AIX operating
system and is isolated from any activity in other partitions. Software failures do not propagate through the
system, and the hardware facilities and microcode isolate the resources.
Dynamic Logical Partitioning
Dynamic logical partitioning provides the ability to logically attach and detach a managed system’s
resources to and from a logical partition’s operating system without rebooting.
For more information on dynamic logical partitioning, see the following:

Affinity Logical Partitions
Some systems have the ability to create affinity logical partitions. Check your hardware specifications to
see if your managed system is capable of using affinity logical partitions. An affinity logical partition is a
special type of logical partition that uses system resources that are in close physical proximity to each
other. When creating an affinity logical partition, the HMC automatically determines which system
resources are to be used, based on their physical location to each other. The system resources that are
automatically managed by the HMC are processors and memory. The user determines the I/O
requirements for each of these partitions. The HMC then creates a profile for each affinity logical partition
and a system profile for the managed system.
Working with Logical Partitions
The logical partition resource allocation provides the ability to select individual components to be added to
a partition without dependencies between these resources. The slots can be freely allocated in any I/O
drawer on the system. Other devices may be required for specific application requirements. It is a good
idea to configure more PCI slots in the partition than are required for the number of adapters. This
provides flexibility by allowing additional adapters to be hot-plugged into the empty slots that are part of an
active partition. Because each partition requires its own separate boot device, the system must have at
least one boot device and associated adapter per partition.
There are a few differences in how AIX runs within a logical partition, as opposed to how it runs on a
standalone server:
v In order for AIX to run inside a logical partition, AIX calls the Hypervisor in place of its traditional direct
access to the hardware and address-mapping facilities.
v Some direct-access calls are presented for diagnostic purposes, and alternate return codes for
Run-Time Abstraction Services (RTAS) calls are used whenever an illegal operation is issued.
v No physical console exists on the partition. While the physical serial ports on the system can be
assigned to the partitions, they can only be in one partition at a time. To provide an output for console
messages and also for diagnostic purposes, the firmware implements a virtual tty that is seen by AIX as
a standard tty device. Its output is sent to the HMC. The AIX diagnostics subsystems use the virtual tty
as the system console.
v Certain platform operations are constrained in LPARs. For example, in non-LPAR systems, platform
firmware updates can be performed from AIX by a root user. Because firmware updates can affect all
partitions in an LPAR system, the LPAR administrator can specify that a particular partition (or no
partition) has this authority. Within that partition, firmware updates work in the same way as they do for
non-LPAR systems.
Apart from these considerations, AIX runs within a partition the same way it runs on a standalone server.
No differences are observed either from the application or the administrator’s point of view. Third-party
applications need only be certified for a level of AIX that runs in a partition, and not for the LPAR
environment itself.

AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
Full System Partition
A special partition called the Full System Partition assigns all of your managed system’s resources to one
large partition. The Full System Partition is similar to the traditional, non-partitioned method of operating a
system. Because all resources are assigned to this partition, no other partitions can be started when the
Full System Partition is running. Likewise, the Full System Partition cannot be started while other partitions
are running. It is recommended that you choose to use either the Full System Partition or create other
partitions. It is not recommended that you switch between these two options frequently, because your I/O
usage might be affected.
Partition Roadmap
Use the following illustration to help you locate information about understanding, planning for, and
configuring partitions, as well as information about installing the AIX operating system.
Figure 2. Partition Roadmap. This illustration shows the logical partition concepts and the books that contain this
information. The Hardware Management Console Installation and Operations Guide contains information about
understanding LPAR, planning LPAR, and configuring LPAR. The AIX 5L Version 5.2 AIX Installation in a Partitioned
Environment guide contains information about installing AIX in an LPAR (such as CD installation and Network
Installation Management installation); and additional considerations for running in LPAR (such as remote management,
dump devices, system backup and restore, and system maintenance).
When to Implement Logical Partitions
A logically partitioned environment adds to a portfolio of solutions that can provide better management,
improved availability, and more efficient use of resources. This section provides some scenarios where a
logically partitioned environment brings significant benefits, as well as other scenarios where it may not be
appropriate.
Server Consolidation
A server with sufficient processing capacity that is capable of being partitioned can address the need for
server consolidation by logically subdividing the server into a number of separate smaller systems. In this
way the application-isolation needs can be met in a consolidated environment, with the additional benefits
of reduced floor space, a single point of management, and easier redistribution of resources as workloads
change.
Chapter 2. Overview of Partitioning
9
Mixed Production and Test Environments
Generally, production and test environments should be isolated from each other. Partitioning enables
separate partitions to be allocated for the production and test systems, eliminating the need to purchase
additional hardware and software. When testing has been completed, the resources allocated to the test
partition can be returned to the production partition or elsewhere as required. It might be that the test
environment later becomes the production environment, and extra resources can then be added to the
partition. As new projects are developed, they can be built and tested on the same hardware on which
they will eventually be deployed.
Consolidation of Multiple Versions of the Same Operating System
Starting with AIX 5.1, different versions of AIX can exist within different LPARs in the same system. This
enables a single system to have different versions of the operating system installed to accommodate
multiple application requirements. Furthermore, an LPAR can be created to test applications under new
versions of the operating system prior to upgrading the production environments. Instead of having a
separate server for this function, a minimum set of resources can be temporarily used to create a new
LPAR where the tests are performed. When the partition is no longer needed, its resources can be
incorporated back into the other LPARs.

AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
Chapter 3. Logical Partition Scenarios and Recommendations
This chapter provides an overview of the AIX installation process and various installation scenarios you
can use. Because the managed system may be the first AIX system in your environment (or the first AIX
5.1 system in an AIX 4.3 environment), this information and accompanying recommendations will help
guide you on decisions about installation, maintenance, and system backup.
Overview of AIX Installation Process
Due to the physical configuration of a managed system, use of the Network Installation Management (NIM)
environment to install AIX is recommended. The following table compares how different forms of media
proceed through the AIX installation process:

Introduction to Network Installation Management
This section provides an introduction to the NIM environment and the operations you can perform to
manage the installation of the Base Operating System (BOS) and optional software on one or more
machines. NIM gives you the ability to install and maintain not only the AIX operating system, but also any
additional software and fixes that may be applied over time. NIM also allows you to customize the
configuration of machines both during and after installation. NIM eliminates the need for access to physical
media, such as tapes and CD-ROMs, because the media is a NIM resource on a server. System backups
can be created with NIM, and stored on any server in the NIM environment, including the NIM master. Use
NIM to restore a system backup to the same partition or to another partition. Before you begin configuring
the NIM environment, you should already have the following:
© Copyright IBM Corp. 2001, 2002
11
v NFS and TCP/IP installed
v TCP/IP configured correctly
v Name resolution configured
For any installation procedure, you need a software source to install from, such as the AIX product
CD-ROM. The AIX product CD-ROM contains boot images used to boot the system from the CD-ROM,
installation images, and the installation commands used to install the installation images, as shown in the
following illustration:
Figure 3. An example of an AIX product CD-ROM. This illustration shows an AIX product CD-ROM contains boot
images used to boot the system from the CD-ROM, installation images, and the installation commands used to install
the installation images.
In the NIM environment, the software source is separated into two NIM resources, the LPP_Source and
the SPOT. The LPP_Source is a directory on your NIM server. When the LPP_Source is created,
installation images are copied from the product CD-ROM to the LPP_Source directory, as shown in the
following illustration:
12
AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
Figure 4. An example of an LPP_Source resource.. This illustration shows that when an LPP_Source resource is
created, installation images are copied from the product CD-ROM to the LPP_Source directory.
The product CD-ROM also contains boot images that enable the system to boot from the CD-ROM and
installation commands that are used to install the installation images. This equivalent NIM resource is
called the SPOT (Shared Product Object Tree). The SPOT is a directory that contains the installation
commands that are used to install the installation images from the LPP_Source onto a system. The SPOT
is also used to build the necessary boot images to boot a client system. Separate boot images exist for
each type of adapter (Ethernet, token ring, and so on).
Chapter 3. Logical Partition Scenarios and Recommendations
13
Figure 5. An example of a SPOT resource.. This illustration shows that a SPOT resource contains the installation
commands used to install the installation images from the LPP_Source resource onto a system. The SPOT is also
used to build the necessary boot images to boot a client system.
Scripts are available that configure the NIM environment for you and create the resources necessary to
perform a mksysb installation. The nim_master_setup script creates an LPP_Source and SPOT resource
for you and defines the resources in the NIM environment. The nim_master_setup script will also copy
the update images from your update CD to the LPP_Source and then install the update images into the
SPOT resource.
In addition to the LPP_Source and SPOT resources, several NIM resources can help customize the BOS
installation process and basic network configuration. The following table shows all the NIM resources that
are created with the nim_master_setup script:

Each partition you install will be defined in the NIM environment as a standalone system resource, also
referred to as a NIM client. The nim_clients_setup script allows you to define the partitions as NIM clients
and initiates a BOS installation on the NIM clients.
14
AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
Installation Scenarios
This section contains several scenarios for installing AIX.
Migrating to AIX 5.2 and Configuring Partition Support
In this scenario, you are adding a managed system to an existing environment of systems running AIX 5.1.
The managed system is the first system in your environment that requires AIX 5.2. If you have a system
available to use as a NIM master, or you already have a NIM master, perform the following steps:
1. Migrate the system to AIX 5.2. For the procedure, refer to “Migrate a System to the AIX 5.2
Partition-Ready State” on page 35.
2. Configure the system to be a NIM master. You will use the NIM master to install the system backup on
your partitions. If you do not have an available system to use as a AIX 5.2 NIM master, refer to
“Configure an Initial Partition as a NIM Master to Use NIM to Install the Remaining Partitions” on
page 18.
First AIX System in Your Environment
In this scenario, the managed system is the first AIX system in your environment, and you do not have
another system with a graphics adapter available. In this case, you must use the HMC as both your
software and hardware console.
If you do not have a great deal of experience using AIX, use the procedure described in “Configure an
Initial Partition as a NIM Master to Use NIM to Install the Remaining Partitions” on page 18. This
procedure will create a NIM master on one of the partitions and use its system image to install the other
partitions.
NIM enables you to install and customize your logically partitioned environment. Using the NIM
environment enables you to perform future installation and maintenance tasks more efficiently.
Installing a Partition Using Alternate Disk Installation
You can clone an existing disk image to another disk or disks without using NIM. You may want to do this
if your network is not fully set up, or if you are not sure about your network configuration. However, you
may choose to use NIM at a later time.
You can use the alt_disk_install command to clone a system image to another disk, but you must use the
-O option to remove references in the object data manager (ODM) and device (/dev) entries to the existing
system. The -O flag tells the alt_disk_install command to call the devreset command, which resets the
device database. The cloned disk can now be booted as if it were a new system.
An example of this scenario is as follows:
1. Boot the managed system as a Full System Partition so you have access to all the disks in the
managed system.
2. Configure the system and install the necessary applications.
3. Run the alt_disk_install command to begin cloning the rootvg on hdisk0 to hdisk1, as follows:
# /usr/sbin/alt_disk_install -O -B -C hdisk1
The cloned disk (hdisk1) will be named altinst_rootvg by default.
4. Rename the cloned disk (hdisk1) to alt1, so you can repeat the operation with another disk.
# /usr/sbin/alt_disk_install -v alt1 hdisk1
5. Run the alt_disk_install command again to clone to another disk and rename the cloned disk, as
follows:
# /usr/sbin/alt_disk_install -O -B -C hdisk2
# /usr/sbin/alt_disk_install -v alt2 hdisk2
Chapter 3. Logical Partition Scenarios and Recommendations
15
6. Repeat steps 3 through 5 for all of the disks that you want to clone.
7. Use the HMC to partition the managed system with the newly cloned disks. Each partition you create
will now have a rootvg with a boot image.
8. Boot the partition into SMS mode. Use the SMS MultiBoot menu to configure the first boot device to
be the newly installed disk. Exit the SMS menus and boot the system.
For a full description of alternate disk installation, see the alt_disk_install man page and the AIX 5L
Version 5.2 Installation Guide and Reference.
Adding Your Managed System to an RS/6000 SP Environment
For information about planning, installing, and configuring AIX on RS/6000 SP systems, refer to the
following Web site:
http://www.rs6000.ibm.com/resource/aix_resource/sp_books/pssp/index.html
Advanced Installation Options
You can use several other scenarios to install your partitions by using some AIX advanced functions.
These procedures are documented in the /usr/lpp/bos/README.PARTITION_INSTALL file.
Some installation scenarios covered are the following:
v Preparing an existing root volume group (rootvg) to move to a managed system
v Using the devreset command to rebuild the device ODM database and reset all devices to default
configurations

Configure an Initial Partition as a NIM Master to Use NIM to Install the
Remaining Partitions
In this procedure, you will set up an initial logical partition as a NIM master and server. This procedure
refers to this initial logical partition as the Master_LPAR. It is assumed that AIX is already installed and
configured for network communication in the Master_LPAR. Make sure your network environment is
already defined and working correctly before configuring the NIM environment.
After you verify the correct level of the AIX operating system has been installed on the Master_LPAR, as
the root user, you will set up the NIM environment using the nim_master_setup script. The
nim_master_setup script automatically installs the bos.sysmgt.nim.master file set, configures the NIM
master, and creates the required resources for installation, including a mksysb system backup.
Note: The nim_master_setup script uses the rootvg volume group and creates an /export/nim file
system, by default. You can change these defaults using the volume_group and file_system
options. The nim_master_setup script also allows you to optionally not create a generic system
backup, if you plan to use a mksysb image from another system.
You will then use the nim_clients_setup script to define your NIM clients, allocate the installation
resources, and initiate a NIM BOS installation on the clients. Then using the HMC, you will activate the
client partitions and configure them to boot off the network.
Prerequisites
Before you begin this procedure, you should have already performed the following tasks:
v Use the HMC to create the Master_LPAR logical partition and partition profile. Be sure the
Master_LPAR partition has a network adapter, enough hard-disk space for the NIM resources, and an
assigned CD device. Set the boot mode for the Master_LPAR partition to be Normal mode. After you
have successfully created the partition and partition profile, leave the partition in the Ready state. Do
not activate the partition yet.
v Use the HMC to create logical partitions and partition profiles for each NIM client. Be sure each LPAR
has a network adapter assigned. Set the boot mode for each partition to be SMS mode. After you have
successfully created the partitions and partition profiles, leave the partitions in the Ready state. Do not
activate the partitions yet.
v Configure AIX for network communication on the Master_LPAR. If AIX is not currently installed on any of
the disks in the system, then refer to “Use the CD Device to Manually Install a Partition” on page 30 for
the procedure.
1. Activate the Master_LPAR (Perform this Step in the HMC Interface)
After you have successfully created the Master_LPAR, it is in the Ready state.
Use the HMC to activate the Master_LPAR partition, as follows:
__ Step 1. To activate the Master_LPAR, do the following:
a. Select the Master_LPAR partition.
b. Right-click on the partition to open the menu.
c. Select Activate. The Activate Partition menu opens with a selection of partition profiles. Be
sure the correct partition profile is highlighted.
d. Select Open terminal at the bottom of the menu to open a virtual terminal (vterm) window.
e. Select OK. A vterm window opens for the partition. After several seconds, the login prompt
displays in the vterm window.
18
AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
2. Configure NIM Master and Initiate Installation of Partitions (Perform
These Steps in the AIX Environment)
__ Step 1. Run the oslevel command as follows:
# oslevel
Output similar to the following displays:
5200
The oslevel command reports the maintenance level of the operating system using a
subset of all filesets installed on your system. If the output from the oslevel command
does not show the expected OS level, see “Migrate a System to the AIX 5.2
Partition-Ready State” on page 35 for information about migrating the AIX operating system
to the correct OS level.
__ Step 2. Verify network configuration by running the following commands:
# smitty mktcpip
Select the Network Interface and press Enter.
Confirm or enter your host name, IP address, name server, domain name, default gateway,
as well as ring speed or cable type. Press Enter.
You can also test the network status by using the following netstat command options:
# netstat -C
The -C flag shows the routing table information. Check to make sure your gateway
information is correct.
# netstat -D
The -D flag shows the number of packets received, transmitted, and dropped in the
communications subsystem. Check to make sure the network device is sending and
receiving packet information.
__ Step 3. Insert the AIX 5L for POWER Version 5.2 Volume 1 in the CD device.
Run the nim_master_setup command as follows:
# nim_master_setup
This command configures the NIM environment on the AIX system by installing the
bos.sysmgt.nim.master fileset, configuring the NIM environment, and creating the boot,
nim_script, resolv_conf, bosinst_data, LPP_Source, and SPOT resources. If you plan to
use a mksysb image from another system, the -B flag is used to prevent creating the
mksysb resource. The nim_master_setup script uses the /dev/cd0 device as the default
device. You can specify an alternate location using the -a device=full_path_name option.
The nim_master_setup script uses the rootvg volume group and creates an /export/nim
file system, by default. You can change these defaults by using the volume_group and
file_system options.
Note: The output from the nim_master_setup script is stored in the /var/adm/ras/nim.setup
log file.
__ Step 4. If you are adding new client machines that cannot be resolved on the name server, edit the
/etc/hosts file to add the IP addresses and client host names.
__ Step 5. There are two ways to define the client systems and initiate the BOS Installation. The first
method uses the SMIT interface to define the clients and then uses the nim_clients_setup
script to initiate the installation. The second method allows you to manually edit the client.defs
file and then use the nim_clients_setup script to define the clients with this file and then
initiate the installation. This section describes both methods:
Chapter 4. Installing AIX in a Partitioned Environment
19
v Use SMIT and the nim_clients_setup script, as follows:
a. Run the smitty nim_mkclient fast path and the nim_clients_setup script to define the
client partitions in the NIM environment.
# smitty nim_mkclient
Select Add a NIM Client.
Enter a host name and press Enter.

b. Repeat for each client partition. Use the F3 key to return to the previous menu, and
change the information for each client.
c. Run the nim_clients_setup script as follows:
# nim_clients_setup
The nim_clients_setup command creates a NIM machine group with the clients you
just defined using the SMIT interface, then allocates the LPP_Source, SPOT, mksysb,
bosinst.data, and resolv.conf resources, and finally initiates a NIM mksysb installation.
The NIM mksysb installation uses the generic_sysb resource that was created with the
nim_master_setup script. If you want to use another mksysb image, use the -m
mksysb_path option, and the script defines and uses it to install the partitions. The path
must be local to the master.
v Use a text editor to manually edit the client.defs file and use the nim_clients_setup script,
as follows:
a. Use the vi editor to customize the /export/nim/client.defs file as follows:
20
AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
# vi /export/nim/client.defs
Edit the client.defs file according to your environment. For more information, see the
instructions and examples in the client.defs file. When you are finished editing the
client.defs file, save it and exit the vi editor.
b. Run the nim_clients_setup script to define the client partitions in the NIM environment
as follows:
# nim_clients_setup -c
The -c option specifies using the client.defs file for your client definitions. The
nim_clients_setup command creates a NIM machine group with all the resources
created from the nim_master_setup script and initiates a NIM mksysb installation. If
you want to use another mksysb image, use the -m mksysb_path option, and the
script defines and uses it to install the partitions. The path must be local to the
master.
3. Activate and Install Partitions (Perform These Steps in the HMC
Interface)
__ Step 1.
To activate the partitions, do the following:
a. Select the partition (or partition profile) you want to activate.
b. Right-click on the partition (or partition profile) to open the menu.
c. Select Activate. The Activate Partition menu opens with a selection of partition profiles.
Select a partition profile that is set to boot to the SMS menus.
d. Select Open terminal at the bottom of the menu to open a virtual terminal (vterm)
window.
e. Select OK. A vterm window opens for each partition. After several seconds, the System
Management Services (SMS) menu opens in the vterm window.
__ Step 2. In the SMS menu on the vterm window, do the following:
a. Press the 6 key to select 6 Multiboot.

Chapter 4. Installing AIX in a Partitioned Environment
23
Use a Separate AIX System as a NIM Master to Use NIM to Install Each
Partition
In this procedure, you will use a separate system running AIX 5.2 as a NIM master and server, to use NIM
to install your logical partitions. As with any NIM environment, you must make sure your network
environment is already defined and working correctly.
After the correct level of the AIX operating system has been installed on this separate system, as the root
user, you will set up the NIM environment using the nim_master_setup script. The nim_master_setup
script automatically installs the bos.sysmgt.nim.master fileset from your media, configures the NIM
master, and creates a generic system backup that will be used to install the partitions, as well as the
SPOT and LPP_Source resources.
Note: The nim_master_setup script uses the rootvg volume group and creates an /export/nim file
system, by default. You can change these defaults using the volume_group and file_system
options. The nim_master_setup script also allows you to optionally not create a generic system
backup, if you plan to use a mksysb image from another system to install your partitions.
You will then define your clients using SMIT or using the NIM clients.def file, then use the
nim_clients_setup script to allocate the installation resources, and initiate a NIM BOS installation on the
clients. Then using the HMC, you will activate the partitions and configure them to boot off the network.
Prerequisites
Before you begin this procedure, you should have used the HMC to create partitions and partition profiles
for each partition that you want to install. Be sure each partition has a network adapter assigned. Set the
boot mode for each partition to be SMS mode. After you have successfully created the partitions and
partition profiles, leave the partitions in the Ready state. Do not activate the partitions yet.
1. Configure NIM Master and Initiate Installation of Partitions (Perform
These Steps in the AIX Environment)
__ Step 1. Run the oslevel command as follows:
# oslevel
Output similar to the following displays:
5200
The oslevel command reports the maintenance level of the operating system using a
subset of all filesets installed on your system. If the output from the oslevel command
does not show the expected OS level, see “Migrate a System to the AIX 5.2
Partition-Ready State” on page 35 for information about migrating the AIX operating system
to the correct OS level.
__ Step 2. Verify network configuration by running the following commands:
# smitty mktcpip
Select the Network Interface and press Enter.
Confirm or enter your host name, IP address, name server, domain name, default gateway,
as well as ring speed or cable type. Press Enter.
You can also test the network status by using the following netstat command options:
# netstat -C
The -C flag shows the routing table information. Check to make sure your gateway
information is correct.
24
AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
# netstat -D
The -D flag shows the number of packets received, transmitted, and dropped in the
communications subsystem. Check to make sure the network device is sending and
receiving packet information.
__ Step 3. Insert the AIX 5L for POWER Version 5.2 Volume 1 in the CD device.
Run the nim_master_setup command as follows:
# nim_master_setup
This command configures the NIM environment on the AIX system by installing the
bos.sysmgt.nim.master fileset, configuring the NIM environment, and creating the boot,
nim_script, resolv_conf, bosinst_data, LPP_Source, and SPOT resources. If you plan to
use a mksysb image from another system, the -B flag is used to prevent creating the
mksysb resource. The nim_master_setup script uses the /dev/cd0 device as the default
device. You can specify an alternate location using the -a device=full_path_name option.
The nim_master_setup script uses the rootvg volume group and creates an /export/nim
file system, by default. You can change these defaults by using the volume_group and
file_system options.
Note: The output from the nim_master_setup script is stored in the /var/adm/ras/nim.setup
log file.
__ Step 4. If you are adding new client machines that cannot be resolved on the name server, edit the
/etc/hosts file to add the IP addresses and client host names.
__ Step 5. There are two ways to define the client systems and initiate the BOS Installation. The first
method uses the SMIT interface to define the clients and then uses the nim_clients_setup
script to initiate the installation. The second method allows you to manually edit the client.defs
file and then use the nim_clients_setup script to define the clients with this file and then
initiate the installation. This section describes both methods:
v Use SMIT and the nim_clients_setup script, as follows:
a. Run the smitty nim_mkclient fast path and the nim_clients_setup script to define the
client partitions in the NIM environment.
# smitty nim_mkclient
Select Add a NIM Client.
Enter a host name and press Enter.
Define a Machine
Type or select a value for the entry field.
Press Enter AFTER making all desired changes.

If a menu prompts you for the Type of Network Attached to Primary Network Install
Interface, select the network adapter from the list and press Enter.
In the Define a Machine menu, supply the necessary information by typing in the
entry fields or using the F4 key to open a selection menu. Verify all information is
correct, especially the Hardware Platform Type (chrp), Kernel to Use for Network
Boot (mp), and Network Type. Press Enter when you are finished.

b. Repeat for each client partition. Use the F3 key to return to the previous menu, and
change the information for each client.
c. Run the nim_clients_setup script as follows:
# nim_clients_setup
The nim_clients_setup command creates a NIM machine group with the clients you
just defined using the SMIT interface, then allocates the LPP_Source, SPOT, mksysb,
bosinst.data, and resolv.conf resources, and finally initiates a NIM mksysb installation.
The NIM mksysb installation uses the generic_sysb resource that was created with the
nim_master_setup script. If you want to use another mksysb image, use the -m
mksysb_path option, and the script defines and uses it to install the partitions. The path
must be local to the master.
v Use a text editor to manually edit the client.defs file and use the nim_clients_setup script,
as follows:
a. Use the vi editor to customize the /export/nim/client.defs file as follows:
# vi /export/nim/client.defs
Edit the client.defs file according to your environment. For more information, see the
instructions and examples in the client.defs file. When you are finished editing the
client.defs file, save it and exit the vi editor.
b. Run the nim_clients_setup script to define the client partitions in the NIM environment
as follows:
# nim_clients_setup -c
The -c option specifies using the client.defs file for your client definitions. The
nim_clients_setup command creates a NIM machine group with all the resources
created from the nim_master_setup script and initiates a NIM mksysb installation. If
you want to use another mksysb image, use the -m mksysb_path option, and the
script defines and uses it to install the partitions. The path must be local to the
master.
2. Activate and Install Partitions (Perform These Steps in the HMC
Interface)
__ Step 1.
26
To activate the partitions, do the following:
a. Select the partition (or partition profile) you want to activate.
b. Right-click on the partition (or partition profile) to open the menu.

Update an Existing NIM Environment to the Latest AIX Recommended
Maintenance Level
Use this procedure to update an existing NIM environment that was created with the nim_master_setup
script to the latest recommended maintenance level of AIX.
Prerequisites
Before you begin this procedure, you should have already created a backup of the system. For instructions
on how to create a system backup, refer to the AIX 5L Version 5.2 Installation Guide and Reference.
1. Update Your NIM Environment to the Latest Recommended
Maintenance Level (Perform These Steps in the AIX Environment)
__ Step 1. Insert the latest AIX update CD into the CD-ROM drive.
__ Step 2. Update the bos.rte.install fileset by using the geninstall command as follows:
# geninstall -d /dev/cd0 bos.rte.install
__ Step 3. Run the install_all_updates script, as follows:
# install_all_updates -d /dev/cd0
The install_all_updates script will first check if your system is at the latest known
recommended maintenance level.
If your system is not at the latest known recommended maintenance level, then the
install_all_updates script updates the system to the latest maintenance level of AIX.
Note: The output from the install_all_updates script is in the
/var/adm/ras/install_all_updates.log log file.
__ Step 4. After the update is complete, the system will instruct you to reboot the system. Reboot the
system by using the shutdown command as follows:
# shutdown -Fr
__ Step 5. Run the nim_update_all script to update the NIM resources that were created by the
nim_master_setup script, as follows:
# nim_update_all
Output similar to the following displays:
############################## NIM update all ##############################
#
#
# During script execution, NIM client and resource updating times
#
# may vary. To view the install log at any time during nim_update_all,
#
# run the command: tail -f /var/adm/ras/nim.update in a separate screen.

Chapter 5. System Backup, Dump, and Storage Management
Most system backup, dump, and storage-management solutions depend on I/O devices. On a partitioned
system, I/O devices (such as tape or CD-ROM) are not always available to all partitions. This chapter
offers recommended solutions to minimize transfer of I/O devices among partitions.
System Backup
A system backup is a copy of the root volume group (rootvg) of your system and is often referred to as a
mksysb, in reference to the command used to create the system backup. The root volume group contains
the following:
v
v
v
v
Startup commands
Base Operating System commands and files
System configuration information
Optional software products
All mounted JFS (Journaled File Systems) and JFS2 (Enhanced Journaled File Systems) in the rootvg are
backed up. Paging space and logical volume information is saved so that the rootvg will be recreated as it
was when the system backup is reinstalled. If there are JFS or JFS2 file systems that are not to be
backed up, you can use an exclude list or you can unmount them before the backup is made.
The following table describes the methods you can use to back up a system.
Table 12. System Backup Methods
Backup Method
Considerations
NIM*
Allows fast backup and recovery of a partition. Because all images are backed up to one
system (NIM master), you should also back up that system and images to other physical
media (tape, CD-RW, DVD-RAM).
mkcd command
Allows creation of a bootable system backup to CD-ROM or DVD-RAM. You can provide
an existing mksysb image from another partition if the backup device is not available at
the partition being backed up.
The mkcd -r command allows backup (not bootable) of images and files to a CD-RW or
DVD-RAM.
mksysb command with a
tape device
Creates a bootable backup only on the partition the drive is connected to. Must boot
from CD or tape to reinstall.
Remote tape drives are supported with Sysback (for more information, see
http://sysback.services.ibm.com).
* Recommended Method
For more information regarding system backups, refer to the AIX 5L Version 5.2 Installation Guide and
Reference. Other options offered during backup creation are excluding file or directories, as well as
creating map files so that the system is restored to exactly the same physical partitions on the disk.
Creating a System Backup
You can create a system backup by using one of the following methods:
Using NIM
With the NIM environment, you can create a system backup that is a selectable resource. That selectable
resource can be used to reinstall the partition on which it was created, or it can be cloned to another
partition. Because of its flexibility, NIM is the recommended method to back up and reinstall your partitions.
© Copyright IBM Corp. 2001, 2002
41
To use NIM to create a system backup, do the following:
1. If your partitions were installed with NIM, go to step 5.
2. On your NIM master, to determine whether your partition is already defined as a NIM client, type:
# lsnim -t standalone
3. If the target partition is not already a NIM client, configure it by running the following on the target
partition:
# smitty niminit
4. On your NIM master, run the following to define the target partition (the partition to be backed up) as a
NIM client:
# smitty nim_mkmac
5. On your NIM master, type the following to open the Define a Resource menu:
# smitty nim_mkres
6. Select mksysb and type the appropriate information. This menu defines the mksysb resource and
also creates the system backup image.
Note: Be sure to change the CREATE system backup image? selection to yes.

Using CD Media
If you have a CD-RW or DVD-RAM connected to one of your partitions, you can create bootable system
backups. You can use the mkcd command to create a bootable image on or mount a mksysb image to
another partition or system that has the device to create and burn the bootable image. Therefore, the
device can be assigned to only one partition when creating backup CDs from multiple partitions. To
reinstall the systems, you must assign a CD device to the partition being reinstalled.
To create a backup to CD media, do the following:
1. Type:
# smitty mkcd
You are asked whether you are using an existing mksysb image. If you want a backup of this
partition, answer No to this question.
42
AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
If you do use an existing mksysb image (possibly from another partition), answer yes. You must
enter the location (including the image name) of the existing mksysb.
2. If you want to save the bootable CD image to burn later, answer no to the Create the CD or DVD
now? selection.
To burn the CD or DVD at a later time (or to burn additional media), run the following:
# burn_cd /dev/cd1 /mkcd/cd_images/cd_image_12510
The image name cd_image_12510 includes the process ID. The process ID displays when the mkcd
command executes.
For further information about creating system backups on CD or DVD, see the AIX 5L Version 5.2
Installation Guide and Reference, as well as the /usr/lpp/bos.sysmgt/mkcd.README.txt file.
Using Tape Media
If you have a tape drive assigned to your partition, you can create a system backup to tape. To create a
backup to tape, type the following:
smitty mksysb
If you want to back up to a file, you can use a separate file system (ensure that you exclude that file
system when you create the backup) or a file in a user volume group. For further information about
creating a root volume group backup to tape or file, see the AIX 5L Version 5.2 Installation Guide and
Reference.
Installing a System Backup Using NIM
You can use the NIM environment to install a system backup onto one or more of your partitions. NIM is
recommended because of its flexibility and customizing options for installation and system management.
Also, NIM allows for multiple installations at the same time. When you install a system backup onto a
partition other than the original partition, you are cloning a partition system image onto a target partition.
Before you can use NIM to install a system backup, make sure that the following conditions are met:
v Your network environment must be working correctly. The NIM master must be configured correctly, and
the lpp_source, SPOT, and mksysb resources must be defined. Refer to either “Use a Separate AIX
System as a NIM Master to Use NIM to Install Each Partition” on page 24 or “Configure an Initial
Partition as a NIM Master to Use NIM to Install the Remaining Partitions” on page 18 for instructions on
setting up NIM in a partitioned environment.
v The target partitions might not contain the same hardware devices or adapters. If this is the case, then
the mksysb, SPOT, and lpp_source resources will be needed to install the needed device support.
v Because NIM configures TCP/IP at the end of an installation, it is recommended that a bosinst_data
resource be allocated for cloning mksysb installations with the RECOVER_DEVICES field set to no.
This action prevents the BOS installation process from attempting to configure the devices as they were
on the source machine of the mksysb.
1. To use a mksysb resource to install a NIM client, enter the smit nim_bosinst fast path.
2. Select a target for the operation.

automatically from SMIT, initiate a network boot from the client to install it. For instructions on how to
do this procedure, refer to “2. Activate and Install Partitions (Perform These Steps in the HMC
Interface)” on page 26.
System Dump Management
If your machine has more than 4 GB of real memory, a dedicated dump device is created at installation
time. Otherwise, the /dev/hd6 paging space is used as the dump device. If a system crash occurs and
paging space was used as the dump device, the dump is copied to the /var/adm/ras/vmcore.n file by
default, where n is a sequence number. If there is not enough space to perform the copy, the user is
prompted during reboot to save the dump to some other media.
To avoid losing a dump due to a lack of a tape drive configured to the partition, always create a separate
dump device that is the same size as your paging space, given that paging space is currently your dump
device.
To verify your dump device, type smitty dump, and select Show Current Dump Devices. If paging space
is your dump device, the output will be similar to the following:

Storage Management
If you have multiple mksysb images stored on a NIM master (or on some other partition), you can use the
mkcd -r command to store them to CD-R or DVD-RAM. The images to be written to CD-R or DVD-RAM
must be in one directory structure, so that a directory can be passed to the mkcd command as the
starting point of the backup.
Use the mkcd command as follows:
mkcd {-d cd_device} [-r directory] [-R | -S] [-I cd_image_dir] [-D] [-L]
Where:
-d
Specifies the CD-R or DVD-RAM device
-S
Indicates to stop the backup before burning the image (image can be burned at a later time)
-r
Specifies the directory from which to create your CD image
-l
Specifies the directory in which to write the CD image
-R
Saves the CD images (use this flag if you want to burn multiple copies)
-D
Enables debugging for the mkcd command
-L
Creates final CD images that are DVD-sized (up to 4.38 GB)
For example, to back up the stored mksysb images in the /export/nim/mksysbs directory to a DVD-RAM
device (/dev/cd1), and use a temporary file system mounted on the /largefilesystem directory to use as
temporary CD image storage, type the following:
# mkcd -d /dev/cd1 -r /export/nim/mksysbs -I /largefilesystem -L
To verify the mksysb, run the following commands:
# mount -o ro /dev/cd0/mnt
# cd /mnt
# ls

Chapter 6. Remote Management
This chapter discusses how you can use the Hardware Management Console (HMC) to manage your
system remotely. For information about how you can remotely manage partitions through the command
line on the HMC, see the IBM IBM Hardware Management Console for pSeries Installation and Operations
Guide.
Each of the following system-management methods can be performed using the HMC interface or from the
command line.
v Use the HMC client to remotely manage any AIX partition or system. All AIX plug-ins on the AIX system
can be managed remotely from the HMC client, provided that the Web-based System Manager
framework version is compatible. The operating system checks each plug-in for compatibility with the
Web-based System Manager framework. If it is not compatible for that plug-in, a message displays,
indicating that the plug-in cannot be managed by the client.
v Use an AIX partition or system to remotely manage an HMC. All HMC plug-ins on the HMC server may
be managed remotely from the AIX system, provided that the AIX system is at a compatible Web-based
System Manager framework version. Otherwise, an error message displays indicating that the AIX
system cannot manage the HMC server.
v Use Web-based System Manager Remote Client to remotely manage an HMC server. For instructions
on how to install the Remote Client, refer to the AIX 5L Version 5.2 Web-based System Manager
Administration Guide. All HMC plug-ins on the HMC server may be managed remotely from the Remote
Client, provided that the Remote Client is at a compatible Web-based System Manager framework
version. Otherwise, an error message displays, indicating that the Remote Client cannot manage the
HMC server. The only plug-in that is an exception is the Service Agent plug-in.
v Use an HMC client remotely manage another HMC client. All HMC plug-ins on the HMC server may be
managed remotely from the HMC client. The only plug-in that is an exception is the Service Agent
plug-in.
Note: When remotely managing the HMC, the command-line tasks you can perform are limited to
configuration tasks.
For more information on remote management, see either of the following readme files:
v /usr/websm/readme.html
v /usr/websm/readme.txt
Remote Management From the HMC to AIX Partitions
After the partition is configured on the network, you can add the partition as a host in the HMC interface,
as follows:
1. Select Console -> Add -> Hosts.

Figure 6. Adding a host using the console menu.. This illustration shows how to navigate from the console menu to the
hosts selection. To add the partition as a host in the HMC interface, select Console from the menu bar, then select
Add, and then select Hosts.
2. Type the host name of the partition to add. The host will be added to the list.
After the partition is configured on the network, you can open an xterm window to connect to the partition
within the HMC interface by selecting Console -> Open Terminal. Enter either the host name or the IP
address of the system.

Chapter 7. Hints and Tips
This chapter provides hints and tips to help you when working with AIX in a partitioned environment.
Naming Your Operating System Host Name
Each partition, including the Full System Partition, must have a unique host name that can be resolved.
Host names cannot be reused between the Full System Partition and the logical partitions.
If the host name of the partition must be changed, before changing the host name of the partition, do the
following:
1. If your system’s level of AIX is earlier than the 5100-02 maintenance package level, skip this step and
go to step 2.
/usr/sbin/rsct/bin/runact -c IBM.ManagementServer SetRTASPollingInterval Seconds=0
2.
Run the following command:
/usr/sbin/rsct/bin/lsrsrc IBM.ManagementServer Hostname
If the partition is managed by multiple HMCs, multiple entries might exist, because each HMC has its
own entry. The output will be similar to the following:
resource 1:
Hostname
= "hmc1.mydomain.mycompany.com"
3. For each entry, remove the resource using the host name shown. For example, run the following
command:
/usr/sbin/rsct/bin/rmrsrc -s ’Hostname = "hmc1.mydomain.mycompany.com"’ IBM.ManagementServer
You can verify that all entries have been removed by running Step 2 again.
4. Run the following command:
/usr/sbin/rsct/bin/rmcctrl -z
5. Change the host name of the partition.
6. After the host name has been changed, run the following command:
/usr/sbin/rsct/bin/rmcctrl -A

Management Console for pSeries Installation and Operations Guide, order number SA38-0590.
Network Adapter Communication Between Partitions and the HMC
After a partition has been started, it uses the network adapter to communicate with the HMC. Both the
HMC and the partition must be configured so they can use the network adapters to communicate with
each other. The partition must be configured to identify the HMC (or HMCs) on the network. It is
recommended that the network be configured using a Domain Name Service (DNS) server.
You can use either fully qualified host names or short host names to identify partitions and HMCs.
However, it is recommended that each partition and HMC be identified using a fully qualified host name,
as this identification ensures unique naming of all the partitions and the HMC in the network. Fully
qualified host names cannot be more than 100 bytes in length.
The HMC and partitions can also be configured using a short host name, where the domain name is not
defined. This is typically done in a private or test network. If the HMC is defined using a short host name,
you must perform extra network configuration steps to ensure correct communications between the
partitions and the HMC. If you use short host names rather than fully qualified host names, make sure that
the short host names are unique and that the mappings to IP addresses are properly specified.

The search order between the local /etc/hosts file and the DNS can be specified using the
/etc/netsvc.conf file or /etc/irs.conf file.
The following examples illustrate the scenarios supported:
v If you are using DNS and your partition and the HMC are using fully qualified host names, then no
additional network configuration is required.
v If you are using DNS and your partition is using a short host name, such as partition_1 and the HMC
is also using a short host name, such as hmc123, both must be added to the local /etc/hosts file, as
shown in the following:
[email protected]_1
-> cat /etc/hosts
127.0.0.1
loopback localhost
9.3.3.151 partition_1
9.3.3.152 hmc123
v If you are not using DNS and your partition is using a fully qualified host name, such as
partition_1.mydomain.mycompany.com, and the HMC is also using a fully qualified host name, such as
hmc123.mydomain.mycompany.com, both must be added to the local /etc/hosts file, as shown in the
following:
[email protected]_1.mydomain.mycompany.com
-> cat /etc/hosts
127.0.0.1
loopback localhost
9.3.3.151 partition_1.mydomain.mycompany.com
9.3.3.152 hmc123.mydomain.mycompany.com
v If you are not using DNS and your partition is using a short host name, such as partition_1 and the
HMC is also using a short host name, such as hmc123, both must be be added to the local /etc/hosts
file, as shown in the following:
[email protected]_1
-> cat /etc/hosts
127.0.0.1
loopback localhost
9.3.3.151 partition_1
9.3.3.152 hmc123
v Your HMC is using a short host name, such as hmc123, and you would like to use both a fully qualified
host name and a short host name for the HMC. In order for your partition to correctly communicate with
the HMC, you must specify the short host name before the fully qualified host name in the partition’s
/etc/hosts file, as shown in the following:
[email protected]_1.mydomain.mycompany.com
-> cat /etc/hosts
127.0.0.1
loopback localhost
9.3.3.151 partition_1.mydomain.mycompany.com
9.3.3.152 hmc123 hmc123.mydomain.mycompany.com
Shutting Down a Partition
This section provides information about how to shut down a partition by using the HMC and by using AIX.
Using AIX to Shut Down a Partition
When a partition is up, it is in the Running state. To use AIX to shut down a partition, do the following:
1. To restart AIX, on the AIX command prompt, type shutdown -Fr.
54
AIX 5L Version 5.2: AIX Installation in a Partitioned Environment
The partition eventually changes to the Starting state, and the operator panel values display, which
indicates AIX is now rebooting.
2. When the reboot is issued within AIX, the partition will boot according to the contents of the bootlist. To
check the order of the boot devices, type bootlist -m normal -o
3. To shut down AIX, on the AIX command prompt, type shutdown -F.
The partition will eventually change to the Ready state. You have now shut down AIX and its partition.
To start AIX, on the HMC, select Activate. When you select Activate, the HMC uses the boot mode
selection in the partition profile.
Using the HMC Interface to Shut Down a Partition

use the HMC to shut down a partition, do the following:
Select the partition you want to shut down.
Right-click on the partition to open the menu.
Select Operating System Reset.
4. Select Hard Reset. This action sends a halt signal indicating which instance of AIX is to be shut down.
If a vterm window was open while the hard reset was done, the vterm window remains open. The
partition will then be in the Ready state.
To activate the partition, select the partition and press the right mouse button. Select Activate. When you
select Activate, the HMC uses the boot mode selection in the partition profile.
Closing a vterm window does not shut down a partition. However, closing the window logs you off that
session and kills any processes that you are running from that vterm window.
