Installing the HP-UX 11i Operating Environment (part 2) - Loading HP-UX

Loading HP-UX

With the section of the Ignite-UX server, or DVD-ROM if you load from media, having been run, complete the installation by first selecting all the basic information, as shown in Figure 1.

Figure 1. Ignite-UX Display Basic Tab Area Using CLI

The Advanced Installation menu lets you choose from among the menu tab areas with the ability of going back and forth among them until you are satisfied with your choices.

Across the top of the menu display are five tab areas: Basic, Software, System, File System, and Advanced. By pressing the Tab key, each area can be highlighted. To select the highlighted tab area, press the Enter/Return key. This causes that tab area's screen to appear. Within each of these areas are several parameters that can be modified for your specific system. Here are the main features of each tab area:

  • Basic- configuration and environment information.

  • Software- ability to choose optional software to be installed. Mostly the same options that appear under Guided Installation.

  • System- networking parameters. Also configurable via the set_parms command.

  • File System- disk space allocation.

  • Advanced- advanced disk, file system, logical volume, and volume group parameters.

I'll begin to configure the system beginning with the Basic screen, as shown in Figure 3-1.

Here are the items of particular importance:

  • Configuration- I selected HP-UX B.11.23 Default. HP-UX 11i version 2 update 2 is called by its original name, 11.23, in some cases. I could select other operating systems from the Ignite-UX server, including a recovery archive, which was earlier produced for this partition.

  • Environments- Mission Critical OE-64bit is selected in the example. The four OE selections are as follows:

    Mission Critical OE-64bit .>] (HP-UX B.11.23)
                                  Enterprise OE-64bit
                                  Foundation OE-64bit
                                  HP-UX 11i Base OS-64bit
  • Root Disk- the default selection for the root disk is the first internal disk drive. There are two internal drives available to this partition.

  • File System- There are the three following options available in this area the first of which is selected:

    Veritas Volume Manager (VxVM) with VxFS
    Whole disk with VxFS
    Logical Volume Manager (LVM) with VxFS 
  • Root Swap - the system automatically selects an amount twice the size of your main memory, or a maximum of 4,096 MB. Consider your primary swap space very carefully. The partition has 16 GB of memory so the maximum of 4,096 is selected.

  • Languages- I'll install English on this system; however, many languages are available for 11i systems.

  • Additional - this is the pick at the bottom-right corner of the screen, not the tab area. Here, you can configure such things as creating an /export volume, create a EFI partition since this is an Integrity server, create second swap area, add disk drives to the root volume, and disabling Dynamic Host Configuration Protocol (DHCP.) With 11i, DHCP, Dynamic Host Configuration Protocol, works with an Ignite-UX server that automatically assigns system name, IP address, and so on.

Moving to the Software tab area, you see a small portion of the software listing on the Ignite-UX server for 11i that has been marked for installation as part of Mission Critical Operating Environment shown in Figure 2.

Figure 2. Software Tab Area with Category All

Although you can't see it in Figure 2, the Category of software selected is All. Other software that you may want to install can be selected from the installation source. In this figure the first two items have been selected automatically as part of the Mission Critical Operating Environment. At this point, you could select additional software, such as Ignite, which you want to load for all operating systems on your Ignite-UX server, and Netscape Directory Server in this window. The full Mission Critical OE is available for selection. If you were installing from a DVD, you might have additional media from which to load and select software. This is done using Software Distributor.You may want to look at this overview to get a feeling for the type of functionality that Software Distributor offers. The swinstall program is the Software Distributor program used to install software.

You could select one of the other categories, such as HPUXAdditions, which would show software such as Bundle11i.

The System tab area, shown in Figure 3, is where system identification-related configuration information can be found. Because I want to configure networking and related information after the installation is complete, I change only the first item on this screen. The options for the first item are as follows:

Final system parameters: [Set parameters now]
                         [Ask at first boot]

Figure 3. System Tab Area

I select Set Parameters Now.

The File System tab area, shown in Figure 3, is of particular importance. Here, you can change file system sizes. You probably won't be satisfied with the default sizes of some of the logical volumes. I normally spend some time in this tab area increasing the sizes of some of the logical volumes. Figure 4 also shows the layout of the File System screen and the values of three of the logical volumes. /stand is highlighted in this example, so the parameters related to it appear under Usage, Size, and so on.

Figure 4. File System Tab Area

To make logical volume size changes, select the mount directory of the logical volume, tab down to Size, and enter the desired new size. In addition to Size, several other parameters are related to the logical volume that you can change.

Notice that Avail shows you how much disk space is left to be allocated on your disk drive. It is perfectly all right to leave some disk space unallocated. This gives you a cushion for when you need to increase disk space down the road.

After making all the volume size-related modifications, you are ready to install the system. However, you first want to choose the Show Summary option, which is toward the bottom of the screen. This option shows you a summary of all the changes you made. This gives you a chance to make sure that you didn't forget something. Figure 5 shows the General Summary screen.

Figure 5. General Summary Screen

This screen provides information on the software you have selected to load and information on your logical volumes. Although you can view items on this screen, you'd have to go back to previous screens to make modifications to the items.

Figure 6 shows the Hardware Inventory Summary screen.

Figure 6. Hardware Inventory Screen

The Hardware Inventory screen information provides a summary of system hardware.

Becasue I am satisfied with all the modifications I have made, I'm ready to load the operating system. I choose OK, which appears at the bottom of all the tab area screens. The screen in Figure 7 appears.

Figure 7. Go! Screen

The screen in Figure 7 warns me that there is an operating system already present my our target disk, but I want to proceed with the installation anyway, so select Go!. The load of the HP-UX is automatic at this point, and you can come back in an hour or so to check the log file to see if loading the operating system completed successfully.

It may be that your HP-UX 11i Operating Environment requires more than one DVD-ROM to complete the installation. In this case, you are prompted to insert the additional media. This is an additional reason to set up an Ignite-UX server to accomplish much faster and efficient initial loads of operating systems, as well as add-on loads of applications, patches, and so on. I almost invariably set up Ignite-UX servers in environments in which many partitions need to be installed and maintained. The initial system load needs to take place from media.

As part of the operating system load process under the System tab, I specify a system name, IP address, subnet mask, and some other information. You would specify this information after the load takes place if you choose not to enter it when the initial load occurs.

The next section covers the set_parms program that runs after system installation if you do not enter Network Configuration during system installation.
