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.

Chapter 1. Getting Started 5 6 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: © Copyright IBM Corp. 2001, 2002 7 v The Reassigning Partition Resources Dynamically section in the IBM Hardware Management Console for pSeries Installation and Operations Guide, order number SA38-0590. v The Dynamic Reconfiguration section in the AIX 5L Version 5.2 General Programming Concepts: Writing and Debugging Programs. v The Dynamic Reconfiguration Safe and Aware Programs section in the AIX 5L Version 5.2 General Programming Concepts: Writing and Debugging Programs. 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. 8 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. 10 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: Table 4.

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: Table 5. NIM resources created by nim_master_setup script NIM Resource Name Given Description spot* 520spot_res Commands used during installation.

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 16 AIX 5L Version 5.2: AIX Installation in a Partitioned Environment Chapter 4. Installing AIX in a Partitioned Environment This chapter contains procedures to install the AIX operating system in a partitioned environment. For more information on concepts and the considerations involved when performing a base operating system installation of AIX, refer to the AIX 5L Version 5.2 Installation Guide and Reference. For more information on concepts and the requirements involved when using the Network Installation Management (NIM) environment to install and maintain AIX, you can also refer to the AIX 5L Version 5.2 Installation Guide and Reference. For instructions on how to create a partition and allocate I/O resources to a partition, see the IBM Hardware Management Console for pSeries Installation and Operations Guide, order number SA38-0590. To help you keep track of the LPAR environment system resources, see the tracking worksheets in the IBM Hardware Management Console for pSeries Installation and Operations Guide. Note: For the installation method that you choose, ensure that you follow the sequence of steps as shown. Within each procedure, you must use AIX to complete some installation steps, while other steps are completed using the HMC interface. Table 6.

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. Define a Machine Type or select a value for the entry field. Press Enter AFTER making all desired changes. * Host Name of Machine (Primary Network Install Interface) [Entry Fields] [lpar1] 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. Define a Machine Type or select values in entry fields. Press Enter AFTER making all desired changes. [TOP] * NIM Machine Name * Machine Type * Hardware Platform Type Kernel to use for Network Boot Primary Network Install Interface * Cable Type * NIM Network * Network Type * Ethernet Type * Subnetmask * Default Gateway Used by Machine * Default Gateway Used by Master * Host Name Network Adapter Hardware Address [Entry Fields] [lpar1] [standalone] [chrp] [mp] bnc [ent-Network1] ent Standard [] [] [] lpar1 [0] + + + + + 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.

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.

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.

Installing AIX in a Partitioned Environment 39 40 AIX 5L Version 5.2: AIX Installation in a Partitioned Environment 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. Define a Resource Type or select values in entry fields. Press Enter AFTER making all desired changes. * * * * Resource Name Resource Type Server of Resource Location of Resource Comments Source for Replication -ORSystem Backup Image Creation Options: CREATE system backup image?

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.

If the client partition being installed is not already a running, configured NIM client, NIM will not automatically reboot the machine over the network for installation. If the client was not rebooted 44 AIX 5L Version 5.2: AIX Installation in a Partitioned Environment 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: COMMAND STATUS Command: OK stdout: yes stderr: no Before command completion, additional instructions may appear below. primary secondary copy directory forced copy flag always allow dump dump compression /dev/hd6 /dev/sysdumpnull /var/adm/ras TRUE FALSE OFF To create and change to a dedicated dump device, do the following: 1. Determine the size of the hd6 paging space (in logical partitions) by running the following: # lsvg -l rootvg The output will be similar to the following: rootvg: LV NAME hd5 hd6 hd8 hd4 hd2 hd9var hd3 hd1 hd10opt TYPE boot paging jfslog jfs jfs jfs jfs jfs jfs LPs 2 53 1 9 130 2 8 1 5 PPs 2 53 1 9 130 2 8 1 5 PVs 1 1 1 1 1 1 1 1 1 LV STATE closed/syncd open/syncd open/syncd open/syncd open/syncd open/syncd open/syncd open/syncd open/syncd MOUNT POINT N/A N/A N/A / /usr /var /tmp /home /opt In the preceding example, the paging space is 53 LPs (logical partitions) in size. 2. To create a dump logical volume, type: smitty mklv When you are prompted for the volume group, type rootvg. 3.

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 5. System Backup, Dump, and Storage Management 47 48 AIX 5L Version 5.2: AIX Installation in a Partitioned Environment 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. © Copyright IBM Corp. 2001, 2002 49 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. 50 AIX 5L Version 5.2: AIX Installation in a Partitioned Environment Figure 7. Opening an xterm window.. This illustration shows how to open an xterm window to connect to a partition. To open an xterm window in the HMC interface, select Console from the menu bar, and then select Open Terminal. Enter the host name or IP address of the system. Chapter 6. Remote Management 51 52 AIX 5L Version 5.2: AIX Installation in a Partitioned Environment 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 For information on updating the partition information on the HMC, see the IBM IBM Hardware 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. © Copyright IBM Corp. 2001, 2002 53 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 To 1. 2. 3. 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. Chapter 7.
