Viewing or Modifying Configuration

If you selected OK on the previous screen, or if you have only one target disk, you will next see the Select Whole-System configuration screen. This screen asks for the file system layout you want, Standard Whole-Disk (non-LVM), LVM ("Logical Volume Manager"), or LVM with VxFS (Journaled File System).

Figure 2-14 Title not available (Viewing or Modifying Configuration)

Workstation installation is shown as Standard Whole-Disk (non-LVM). If a disk is larger than 2 GB, LVM is required.

The default for Servers is LVM configuration, with the exception of disks smaller than 1 GB. In most cases, especially with multiple disks, you will want to configure as LVM.

	NOTE: Starting from the HPUX 10.20 version, /stand is created as a separately mounted file system. The /stand file system will always reside on the first logical volume on the boot disk. The following default sizes will be used for the root and the boot file systems : Root FS "/" : 84 MB Boot FS "/stand" : 48 MB You can choose either HFS or VxFS as the root file system.

For More Information

To find out more about LVM and VxFS, see the manual System Administration Tasks. The basic procedure for installing the optional HP OnlineJFS Product, which gives you the complete functionality of VxFS, is in “Installing the Optional OnlineJFS Product ”, in this manual.

	NOTE: For newer Server systems with a selected system root disk that is smaller than 1 GB, non-LVM configuration is the default selection. This is in order to accommodate the HP-UX 10.x file system layout. The LVM configuration calls for separate logical volumes to contain (at least) the following : /, /usr, /stand, /opt, /var, /tmp, and "primary swap" On a small root disk, it is better to load everything under the root file system ("/") and take advantage of a common pool of free disk space. If your system has multiple disks and you want to combine more than one disk into the LVM root volume group, override the Standard Whole-disk default for "smaller disks", and specify Standard LVM configuration.

View/Modify Basic Configuration

Figure 2-15 Title not available (Viewing or Modifying Configuration)

This screen allows you to modify disk configuration. The screen shown above is for an LVM configuration; not all of these fields will appear on the non-LVM screen.

Pressing Enter (or the space bar) at each question will display a mini-menu for that item. If you need to change a parameter, use the arrow keys to highlight the selection on the mini-menu and press Enter again to choose that selection.

	NOTE: To load only OS-related software without ONC+ software enhancements: leave the value "false" for the question "Load 10.20 software enhancements".

Help information which is specific to each parameter can be displayed by pressing f1 (or CTRL-f) while the parameter of interest is highlighted.

One of the parameters you can choose in this screen is "Software Language." See the manual Localized System Configuration Overview (HP Part No. B3782-90095) for additional requirements for each language.

You can also select the Locale setting for your system. This will determine other language-environment conventions such as time and monetary conventions in software messaging.

If you plan to configure multiple disks into the root volume group, you should ensure that the selection Make Volatile Dirs Separate is set to True. This allows the root file system to expand as needed and the volumes to be spread across more than the root disk. (See “Adjusting File System Size ” for details on expanding a file system after installation.)

Choose OK when you have made your selections.

Configuring the Disk and File System

Figure 2-16 Title not available (Configuring the Disk and File System )

A screen display similar to this summarizes your configuration and allows you to make modifications by selecting Modify Disk Parameters or Modify FS Parameters. You can also accept the default values by tabbing to OK and pressing Enter. If you do this, go to “Loading the Core Operating System ” in this chapter.

• If you select Modify Disk Parameters or Modify FS Parameters, you will see a screen for additional parameters. (The disk in the example is in the root volume group("vg00").

• Choosing Cancel will return you to the previous screen.

	NOTE: If you choose OK, you may see a warning screen indicating that one or more of your target disks already has a file system on it. In the warning screen, choose Continue to proceed, if you are not concerned about any data that may exist on the target disk. OR If you want to change target disks, choose Modify Configuration and Cancel to successively "back out" to the Root Disk Selection Screen.

Specifying Disk Usage

If you selected Modify Disk Parameters, in the screen shown in Figure 2-16 “Title not available (Configuring the Disk and File System )”, you will see a screen similar to the following:

Figure 2-17 Title not available (Configuring the Disk and File System )

Using this screen, you can modify disk usage or parameters. The most typical use of this screen would be to configure a second disk.

For example, you could modify the disk configuration first, and then go on to modify the file system, as in the following sample procedures. Tab to OK and press Enter if values are satisfactory.

Example:

1. On the Specify Disk Usage screen, select a disk with the arrow keys and tab to the fill-in fields to change any of the usage items. Note that the "blank" fields allow direct entry of information; the bracketed fields have underlying mini-menus which you can display by selecting the item and pressing the space bar. In a mini-menu, highlight an item by using the arrow keys and choose it by pressing Enter. When you have finished, use arrow keys to highlight Modify (if you have made modifications) and press Enter.

2. To modify disk or volume group parameters (LVM), or simply use the defaults, choose from the following actions:

   • Tab to Modify Disk Parameters... and press Enter. You will see Figure 2-18 “Title not available (Configuring the Disk and File System )”. Go to the next section, "Modifying Disk Parameters". OR

   • Tab to Modify Volume Group Parameters and press Enter. You will see Figure 2-19 “Title not available (Configuring the Disk and File System )”. Go to the section "Modifying Volume Group Parameters". OR

   • Tab to OK and press Enter to leave the screen when everything is satisfactory. Go to the section “Loading the Core Operating System ”, in this chapter.

Modifying Disk Parameters

If you selected Modify Disk Parameters in the screen shown in Figure 2-17 “Title not available (Configuring the Disk and File System )”, you will see a screen similar to the following:

Figure 2-18 Title not available (Configuring the Disk and File System )

	NOTE: Before you make any modifications to the sub-screens, please note the following: The default parameters are usually suitable and should not be changed unless your disk situation is unusual. Initializing a disk ("mediainit") is both time consuming and generally unnecessary, except in the unlikely event that the disk has incurred low-level formatting damage due to a control malfunction.

If necessary, make any modifications and tab to OK. Then press Enter.

Modifying Volume Group Parameters

If you selected Modify Volume Group Parameters (LVM only) in the screen shown in Figure 2-17 “Title not available (Configuring the Disk and File System )”, you will see a screen similar to the following:

Figure 2-19 Title not available (Configuring the Disk and File System )

If necessary, make any modifications and tab to OK. Then press Enter.

After you have viewed or modified the parameters in each sub-screen, you will see the Specify Disk Usage Screen (Figure 2-17 “Title not available (Configuring the Disk and File System )”) again summarizing the current status of disk usage.

Configuring File Systems

If you selected Modify (FS) Parameters in the screen shown in Figure 2-16 “Title not available (Configuring the Disk and File System )”, you would see a screen similar to the following:

Figure 2-20 Configure File Systems

On this screen, you can configure file system space and usage, and you can also change Logical Volume parameters or other file system parameters in subsequent screens, as needed. As with disk usage, the default parameters are usually suitable and should not be changed unless your file system requirements are unusual.

Example:

You can change file system configuration by doing the following:

1. Move the cursor to highlight the mount directory item, such as "/home", in the top box. Use the arrow key to move the cursor within lists, and use the Tab key to move between lists and major items.

   For example:

   1. Use Tab to move the cursor to the "Size" field, or another item in the lower half of the screen.

   2. Leave the default size or change it to another appropriate value. To edit, you can backspace over the old entry and type in a new one. For the fields followed by ">", highlight the field and press the space bar to get a mini-menu of selections. Highlight one of these and choose it by pressing Enter.

   3. When you have finished, choose Modify (for changing volume size) or choose Add or Remove for other changes.

   4. When you are satisfied with the parameters, choose OK to accept the changes and return to the System Configuration screen. Otherwise, choose Cancel to reject the changes and return to the previous screen.
