13.3 Guided Installation

13.4 Advanced Installation

13.5 Initial System Configuration

The installation process starts by interrupting the normal boot process of an HP system. In the normal boot process, a server or workstation tries to boot from the primary boot path. By interrupting this boot process, you can specify a different boot path containing HP-UX Install and Core OS installation media. For a successful system installation process, you need to determine the type of your hardware and check its compatibility with the HP-UX version you are installing. If the HP-UX version is supported on your system, you can use Core OS Media (usually a CD-ROM) to install HP-UX. Once you start the installation process, you can select guided installation, advanced installation, or an installation with default values. Installation with default values requires minimum user interaction. During the installation process, you configure system parameters such as the HP-UX environment, system disk, swap space, and Logical Volume Manager (LVM) file systems. You can also select the system language and the number of user licenses. These parameters are common to both guided and advanced installations. However, when you use the advanced installation method, you can also make network settings and changes to logical volume sizes. An example of

creating logical volumes on a 4-GByte disk space will be presented during the advanced installation process (Section 13.4).

After the installation process is complete, HP-UX restarts the computer, and you can log into HP-UX as user root and carry out postinstallation tasks. These tasks include installation of additional patches and applications. You may also have to install software drivers if a device driver is not already built into the kernel. An important task is to tune kernel parameters depending on the applications being installed. The kernel configuration process is discussed in Chapter 16.

This chapter starts with a brief introduction to HP servers and workstations. Then we will walk through an installation process on a server, where guided installation and advanced installation methods will be discussed.

13.1 Introduction to HP Workstations and Servers

On older machines, HP used 700-series numbering on workstations and 800-series numbering on servers. This convention has been changed, and all of these systems are now called 9000-series servers and workstations. The most common types of HP servers for entry-level solutions are the L-series, A-series, and R-series. For midrange use, K-Series and N-Series servers are recommended. The V-series servers are the most powerful machines from HP. These are considered best for performance, availability, and scalability. HP-UX workstations have the high performance and graphical capabilities required for personal or office use.

HP-UX has both 32-bit and 64-bit capabilities. Not all HP servers and workstations can run 64-bit HP-UX. Before installation, you need to know which CPU you have and whether it supports the 64-bit version of operating system.

Processor Dependent Code (PDC) is used to check and verify hardware configuration at boot time. It detects and shows what hardware devices are available to the system. From an installation point of view, you use PDC to determine the disks and CD-ROM drives attached to the system so that you may specify the installation device and boot options. There are minor differences in

PDC commands for different servers and workstations. After checking the attached devices, the PDC tries to boot a machine from the primary boot device. You can interrupt the automatic boot process to check what commands are available on your system or boot from a device other than the primary boot device. There are other installation differences between servers and workstations, but in general the procedure applies to both. If you have installed HP-UX on one machine, you are able to install it on the other.

13.2 Installing HP-UX

When you turn on an HP machine, the PDC starts execution and checks system memory and peripherals. Before starting the automatic boot-up from the primary boot device, it stops for ten seconds to allow the user to interrupt the boot process. It displays a message like the following on the screen.

Processor is starting autoboot

To discontinue press a key within 10 seconds.

When you see this message, press the key. You will see a menu of commands such as this.

---------------------- Main Menu --------------------------

Command Description

------- -----------

BOot [PRI|ALT|] Boot from specified path

PAth [PRI|ALT|] Display or modify a path

SEArch [Display|IPL] [] Search for boot device

COnfiguration menu Displays or sets boot values

INformation menu Displays hardware information

SERvice menu Displays service commands

Help [

|] Displays help for menu or cmd

RESET Restart the system

----------

Main Menu: Enter command or menu >

Commands can be abbreviated using uppercase letters as shown. For example, the search command can be abbreviated as sea. From this menu, you can use the boot command to boot the system from a CD-ROM containing the Core Operating System. But before that, you need to know the device name for the CD-ROM drive attached to your system. The search command is used to list all bootable devices attached to the system. This includes disk drives, tape drives,

and CD-ROM drives. The search command will show you an output like the following.

Main Menu: Enter command or menu > search

Searching for potential boot device(s)

This may take several minutes.

To discontinue search, press any key

(termination may not be immediate)

Path Number Device Path (dec) Device Type

----------- ----------------- -----------

P0 10/0/6 Random Access Media

P1 10/0/5 Random Access Media

P2 10/0/4 Random Access Media

P3 10/0/3 Random Access Media

P4 10/0/2 Random Access Media

P5 10/0/1 Random Access Media

P6 10/4/4.2 Toshiba CD-ROM Device

P7 10/4/4.1 Sequential Access Media

Main Menu: Enter command or menu >

On some systems, the output for the search command may be different. This command shows the path number, device path, and type of device. Path numbers are used to refer to a particular device when using commands that operate on devices. Device paths show the physical path associated with the device. The physical path of the device represents a system slot to which the device is attached. Random Access Media shows disks and CD-ROM drives. The Sequential Access Media type is usually used for tape drives.

Once you get this information and figure out which path number represents your CD-ROM drive, you can use the boot command to boot the system from the CD-ROM. If your CD-ROM is represented by P6, the boot command will be as follows:

Main Menu: Enter command or menu > Boot P6

You can also use device paths to boot the system instead of device numbers. After you issue the boot command, the system will ask you if you want to interact with the Initial System Loader (ISL). You have to answer no (N) at this point. This message is like the following.

Main Menu: Enter command or menu > Boot P6

Interact with IPL (Y or N) ?> N

Your Install and Core OS CD-ROM must be present in the drive at this moment. The system starts loading software from the CD and automatically goes into installation mode. A message appears on your screen similar to the following.

Booting . . .

Boot IO Dependent Code (IODC) revision 152

Hard Boot

ISL Revision A.00.38 Oct 26, 1994

ISL booting hpux (;0);INSTALL

You will see some other messages scrolling down when the system detects installed hardware. After these messages, the HP-UX installation/recovery window appears as shown in Figure 13-1. Here, basic instructions for cursor movement and menu selection are provided. A summary of detected hardware is also present. In the bottom section, three options are listed. These are:

Figure 13-1. The HP-UX installation process.

Install HP-UX

This is used to start the HP-UX installation process.

Run a Recovery Shell

This is used to provide access to a recovery system used to recover a damaged system.

Advanced Options

Here you can select different advanced options. I would recommend going to this area and disabling DHCP. This is useful for first-time installation when you want to concentrate on the installation of the operating system without going into any network-related activity.

At this point, you can use the key to navigate different parts of the screen and the key to select an option. I would recommend going to Advanced Options and disabling DHCP (Dynamic Host Configuration Protocol, used to assign IP addresses to hosts automatically) first. Pressing the spacebar key toggles the Enable and Disable options. It is better to disable DHCP during the installation phase. By doing so, you can avoid any problems during booting if the DHCP server is not available at boot time or if you come across a network problem during the installation. You can enable it again after the installation process is complete. A screen similar to the one shown in Figure 13-2 appears when you go to Advanced Options.

Figure 13-2. Advanced Options of the HP-UX installation process.

The asterisk character shows that use of DHCP is enabled by default. Pressing the spacebar key on this option disables it. After disabling DHCP, use the key to go to the OK button and then press the key to return to the screen shown in Figure 13-1. Now you will go to the Install HP-UX option and press the key. The next screen appears, shown in Figure 13-3, where you can select user interface and media options.

Figure 13-3. Selection of User Interface and Media Options.

There are three media selection options as follows.

Media only installation

This option is used to install HP-UX completely from Core OS media supplied by HP, for example, a CD-ROM.

Media with Network enabled

This option is used to install software from another machine on the network that is configured as Software Server. A software server machine contains software depots known as SD depots. Software depots are discussed in Chapter 15.

Ignite-UX server based

This type of installation is used for Ignite-UX.

User interface selection options are shown below. We will discuss Guided Installation and Advanced Installation in more detail in this chapter.

Guided Installation

This is recommended for basic installations.

Advanced Installation

If you want to make LVM and file-system size changes during the installation process, you should use Advanced Installation. Networking parameters can also be set during the Advanced Installation process.

No User Interface

This is the minimum user interaction mode of installation. It takes default values for the installation.

13.3 Guided Installation

The Guided Installation process performs the basic HP-UX installation. When you select this method of installation, you go through a number of steps. At every step, you have to configure one system parameter. After selecting Guided Installation, the first screen looks like the one shown in Figure 13-4.

Figure 13-4. Selection of the overall system configuration.

Figure 13-4 is the first step toward guided installation. In this step you chose the overall system configuration. The default selection is HP-UX B.11.00 Default. Choose Next to go to the next step. You can also press the key to select next. At each following step, you will see similar screens, where you can go to the previous screen by selecting Back instead of Next (not shown in Figure 13-4 as this is the first step in Guided Installation and no previous step is available). The Guided Installation steps are as follows.

1. Selection of overall system configuration as shown in Figure 13-4.

2. Environment selection. Here you can select a particular environment depending on the type of your hardware. For example, you can select 32-bit HP-UX with or without CDE support (CDE is the Common Desktop Environment used as the GUI on UNIX systems).

3. Root disk selection. A default selection is automatically made for you and you will see the disk model, its size, and its hardware path. This is the disk

on which the operating system is going to be installed. The default selection is actually the primary boot device. You can make another selection if you understand how to change the primary boot device in PDC.

4. Selection of root swap area. A recommended value of swap space in megabytes is shown at this step. The amount of physical memory installed in your system is also listed. Depending on your requirements, you can change the swap area. More detail on the swap space can be found in Chapter 22.

5. Select the file system. Here you will find options for a particular type of file system. The options are:

o Logical Volume Manager (LVM) with VxFS

o Logical Volume Manager (LVM) with HFS

o whole disk (not LVM) with HFS

HFS and VxFS are types of file systems. You can find detailed information about these and the LVM in Chapter 18.

6. If you are using the LVM approach, you can put more than one disk in a volume group. During the installation process, the root volume group vg00 is configured, and you can decide how many disks should be included in this volume group. However, if your system has many disks, HP recommends that a maximum of four disks be included in the root volume group. You can also select disk stripping if more than one disk is included in the root volume group. Disk stripping distributes data on all disks and hence increases performance.

7. Select a language. The default language is English.

8. User license selection. The default selection is the 2-User license.

9. Select additional software to be installed with the base HP-UX. Available software categories and products are listed with a short description. Selected software products are marked with Yes, while others are marked No. Make sure that general patches are marked for installation.

10. Preinstall disk information. The installation process will analyze disks used for installation. Any errors or warning messages will be displayed. If a disk already contains the HP-UX file system, you will see a warning message showing that all data on the disk will be erased.

After the above step, select Go, and the actual installation process will start, where file systems will be created on disk(s) and the HP-UX system files will be copied from installation media. This is a long process and may take quite some time depending on the type of your system.

13.4 Advanced Installation

If you select Advanced Installation (Figure 13-3), you will see a screen as shown in Figure 13-5. Here you can select all of the options used in your guided installation. Additionally, you can set the network configuration and make changes to file system sizes in the LVM.

Figure 13-5. Advanced HP-UX installation.

Here you can use the key to move around. When the cursor is over a particular item, you can press the key to change options. The topmost line lists five categories. By selecting a particular category, options related to that

category are listed in the lower part of the screen. In Figure 13-5, you can see the basic configuration options with their default values. You can make changes to any of these. The basic reason for using the Advanced Installation is to make changes to the LVM file systems during the installation process or to make a network setup. Network setup can be performed in the System category of Figure 13-5. Changes to the LVM are made using the File System category. Figure 13-6 shows a screen shot of the File System category for adjusting file system sizes.

Figure 13-6. Adjusting file system sizes during advanced HP-UX installation.

I have selected LVM with VxFS during this process. Default file systems present in this group are listed in this screen. You can scroll the list of file systems using the arrow keys. The following information about each file system is displayed in this screen.

1. Mount directory (Mount Dir) for the file system. Mount directories are automatically created during the installation process.

2. File system usage (Usage) shows the type of file system. All file systems are marked VxFS except the swap area and the file system having /stand as its mount point. The /stand file system is used for the HP-UX kernel, and it is mandatory that it be of HFS type.

3. Size of the file system (Size (MB)) is shown in megabytes.

4. Percentage used (% Used) shows the percentage of the file system that will be

used after the installation process is complete.

5. Volume group name (VG Name). The root volume group name is vg00.

You can use the key to move around this screen and make any desired changes to a particular file system. For this, you have to follow these three steps.

1. Select a file system using the and arrow keys.

2. Make a desired change using the , arrow, and keys.

3. Go to the Modify option using the key and press the key. You can also press M for this purpose.

By default, HP-UX creates a volume group with the name vg00 and creates eight logical volumes in it. You need to adjust these sizes according to your requirements. For example, if you are installing a number of applications, the size of the /opt partition must be larger. On the other hand, if you expect that many users will be creating large files in their home directories, you will increase the size of the /home partition. Assign a reasonable amount of disk space to the /tmp directory, as some applications may create a large number of temporary files in this directory. Swap space is an important issue, and you should leave enough space for this on your disk. On a 4-GByte disk, I create partitions in the sizes shown in Table 13-1.

Table 13-1. Size of Partitions on a 4-GByte Disk

Partition

Size (MBytes)

/

100

/stand

100

Swap

512

/home

200

/opt

800

/tmp

700

/usr

800

/var

800

In addition to adjusting existing logical volume sizes, you can also create new logical volumes and add or remove physical volumes in the volume group.

When you are satisfied with the configuration, press the key on the Go option. The installation process will analyze disks and show any warning or error messages. When you acknowledge these messages, file systems are created, software is copied and the configure process starts, which may take a long time.

13.5 Initial System Configuration

Assuming that the Set System Parameters at First Boot option was chosen from the System tab, at the end of the installation process, the HP-UX kernel is rebuilt and the system reboots. The system will start the initial configuration process after reboot. This process includes a number of steps, and these are carried out by the set_parms command invoked when HP-UX boots for the first time. You will be asked to provide the system name, time zone, root password, and IP configuration data. A typical session of initial configuration is shown here, where boldface letters show user input.

_______________________________________________________________

Welcome to HP-UX!

Before using your system, you will need to answer a few questions.

The first question is whether you plan to use this system on a network.

Answer "yes" if you have connected the system to a network and are ready to

link with a network.

Answer "no" if you:

* Plan to set up this system as a standalone (no networking).

* Want to use the system now as a standalone and connect to a

network later.

_______________________________________________________________

Are you ready to link this system to a network?

Press [y] for yes or [n] for no, then press [Return] y

_______________________________________________________________

Before you begin using this system, you need to obtain the

following information from your local network administrator:

* Your system name (host name).

* Your time zone.

If you do not have this information, you may stop now and

restart your system once you have it.

________________________________________________________________

Do you wish to continue?

Press [y] for yes or [n] for no, then press [Return] y

________________________________________________________________

For the system to operate correctly, you must assign it a unique

system name or "hostname". The hostname can be a simple name

(example: widget) or an Internet fully-qualified domain name

(example: widget.redrock-cvl.hp.com).

A simple name, or each dot (.) separated component of a domain name,

must:

* Start with a letter.

* Contain no more than 64 characters.

* Contain only letters, numbers, underscore (_), or dash (-).

Uppercase letters are not recommended.

NOTE: The first or only component of a hostname should contain 8

characters or less for compatibility with HP-UX `uname'.

The current hostname is myhp.

______________________________________________________________

Enter the system name, then press [Return] or simply press [Return]

to retain the current host name (myhp): myhp

You have chosen myhp as the name for this system.

_______________________________________________________________

You may configure some additional network parameters at this time:

* Subnetwork Mask and Default Gateway

* Domain Name System (DNS)

* Network Information Service (NIS)

Your local network administrator can tell you which if any of these

parameters should be configured for your system, and provide you the

appropriate values.

If you do not have these values now, you can configure them later.

_______________________________________________________________

Do you want to configure these additional network parameters?

Press [y] for yes or [n] for no, then press [Return] n

.

.

To fully utilize the capabilities of your system, you may have to

perform some additional system configuration tasks using the HP-UX

"sam" (System Administration Manager) command. Consult your local

administrator or the "HP-UX System Administration Tasks" manual for

more information.

The system will now complete its boot process, and allow you to login

as '"'root'."

Your minimum installation process is complete at this stage, and the system starts booting. It will show you the starting process of different services and system components as shown below.

HP-UX Start-up in progress

__________________________

Configure system crash dumps .............................. OK

Mount file systems ........................................ OK

Update kernel and loadable modules ........................ N/A

Initialize loadable modules ............................... N/A

Setting hostname .......................................... OK

Finally you will see a login prompt. At this point, you can log in as user root. Your system has the core software installed, and you can start the installation of additional software applications and patches.

When installing HP-UX, you can leave undone many of the steps in the initial system configuration. These steps can be completed later, after logging in as root and restarting the initial configuration process. To restart this process, use the set_parms command. If you use this command without any arguments, it will show you the following message.

Usage: set_parms

Where can be:

hostname

timezone

date_time

root_passwd

ip_address

addl_netwrk

or initial (for entire initial boot-time dialog sequence)

Using one of these listed options, you can repeat a partial configuration or reconfigure your system for all options. If you want to configure only one parameter, use the proper argument with the set_parms command. For example, to set the time zone only, use the command set_parms timezone. If you want to set all parameters, use the set_parms initial command and it will go through all steps. Depending on the type of terminal you are using, the set_parms command

will start either in text-based or GUI mode. The options in both of the modes are the same. Let's start the set_parms initial command in GUI mode.

Just after starting the command, you will see a window as shown in Figure 13-7.

Figure 13-7. The first window after starting the set_parms command.

This window shows you initial information. If you want to connect the system to the network at this point, select Yes; otherwise select No. In this example, I selected Yes. After the selection is made, the next window appears and is shown in Figure 13-8.

Figure 13-8. Basic information needed for system setup.

Figure 13-8 shows the basic information you need to set up the system. The information is the system name, the IP address for the system, and the time zone. After pressing the Yes, Continue button, you move to the next window, shown in Figure 13-9.

Figure 13-9. Selecting the system name.

At this point, you enter a name for your system. Rules for the system name are mentioned in this figure. You can type the name in the box provided for this purpose. If you are on a network, you must have a naming convention to avoid any duplicate names. A name must start with a letter, although it can contain any number of numeric characters. A host name must not be longer than 64 characters. Once you enter the host name and press the OK button, another window will appear that will ask you to confirm the host name you have typed in.

After pressing the Yes button, you will move to the window shown in Figure 13-10, where you will select your location. The window shown in Figure 13-11 is used for time zone selection. First you select your location and then the actual time zone.

Figure 13-10. Selecting the location.

Figure 13-11. Selecting the time zone.

When you have made the selection for the time zone, HP-UX will show you the selection you have made. You will be asked to confirm the selection as shown in Figure 13-12. As you can see, the selection made is U.S. Eastern Standard time with daylight savings. This time is a 5-hour difference from Greenwich Mean Time, or GMT (EST5EDT).

Figure 13-12. Confirmation for the time zone selection.

The next window will show the current time on your system clock, and you need to confirm it. If the time is not correct, you may answer No in Figure 13-13 and then select the correct time.

Figure 13-13. Selecting the system time.

After this, you will select the root password. Information about the root password is provided in Figure 13-14, while Figure 13-15 is used for selecting the root password.

Figure 13-14. Information about the root password.

Figure 13-15. Selection of the root password.

You have to type the root password twice to confirm the password, as shown in Figure 13-15. If you provide the same password both times, a confirmation window appears as shown in Figure 13-16.

Figure 13-16. Password confirmation window.

Now you move to the IP address part of the configuration process. Figure 13-17 shows the window for entering the IP address of your machine.

Figure 13-17. Selecting the IP address.

After this, you may need to enter some other information such as the Subnetwork Mask, Default Gateway address, and Domain Name System name, as shown in Figure 13-18. This is the last part of the set_parms command session. Pressing the No button will terminate the command (I did the same), while pressing the Yes button will show you additional windows for these network configuration tasks.

Figure 13-18. Selecting additional network parameters.

Postinstallation Tasks

If your system has some hardware that needs additional software drivers not already built into the kernel, you may need to install these drivers after completing the installation process. For example, if there are 100-Base-T Ethernet or gigabit Ethernet adapters installed, you may need to install the drivers using CDs provided by HP. The process of installing any additional software involves the HP Software Distributor (SD-UX) which is discussed in Chapter 15.

After installing any drivers that necessitate rebuilding a new kernel, the SD-UX will automatically rebuild the kernel and reboot the system for you. For configuring these additional interfaces, use SAM (Chapter 12).

Chapter Summary

This chapter is included to give you a brief overview of the HP-UX installation process. In the start of the chapter, there was an introduction to HP 9000 servers and workstations. The Processor Dependent Code (PDC) controls initial bootup tasks, such as memory and CPU tests and the detection of attached peripherals. It determines the primary boot device and tries to boot HP-UX from the device. You can interrupt this process and use the search command in PDC to look for

additional bootable devices. You can then boot from a device containing the HP-UX installation media.

Once the system boots from the HP-UX Install and Core OS installation media (usually a CD-ROM), you are prompted to either install HP-UX or run a recovery shell. When you select Install HP-UX, you have to select the source location and user interface. You can choose any of the three user-interface options.

1. Guided Installation is used for a basic install.

2. Advanced Installation is used for configuration of LVM file system sizes and network setup.

3. No User Interface is used to install HP-UX with all default values and minimum user interaction.

In the first two options, you can specify a number of options for installation parameters. After the installation process is complete, the system rebuilds the kernel and reboots itself. After the first boot, you can configure the system and connect it to the network. You can modify the initial configuration at any time using the set_parms command.

If your system contains additional devices for which drivers are not included in the standard HP-UX distribution, you need to install the drivers using SD-UX. After that, you can configure these devices with the help of SAM.

In the next chapter, you will learn about the HP-UX startup and shutdown processes.
