Step 5. Verifying or changing the installation settings

Follow this procedure for verifying or changing the installation settings.

Verify the default installation settings from the Installation and Settings window. If the installation and system settings are correct, type 0 in the Choice field and press Enter. Confirm that the selections on the installation summary window are correct, and press Enter to begin the BOS installation. Go to Step 6. Finishing the BOS installation.

To change the installation settings, use the following procedure:

Select either New and Complete Overwrite Installation or Preservation Installation.
1. Type 1 in the Choice field to select the System Settings option.
2. When the Change Method of Installation window displays, type the number corresponding to wanted installation (either 1 for New and Complete Overwrite or 2 for Preservation) in the Choice field and press Enter.
  Note: Available installation methods depend on whether your system has a previous version of AIX® installed.
  If you want to install the next maintenance or technology level of AIX, see Preparing to install optional software products and service updates. You can also use the SMIT update_all fast path or the install_all_updates command to update existing filesets to the next maintenance or technology level.
3. When the Change Disk(s) window displays, you can change the destination disk for the installation. If you selected the preservation or migration installation, the window lists only disks containing a rootvg.
  For New and Complete Overwrite, the disk name, the location code, the size of the disk, and the root volume group status is displayed for each available disk. The Bootable column indicates whether the disk is bootable.
  
  For Preservation, the level of the base operation system for the root volume group, the disks in the root volume group, the location code, and the size of the disk is displayed.
  
  Type 77 to select Display More Disk Information to view additional disk attributes such as physical volume identifier, device adapter connection location, or physical location code.
  If the default shown is correct, type 0 in the Choice field and press Enter. To change the destination disk, use the following procedure:
  1. Type the number for each disk you choose in the Choice field and press Enter. Do not press Enter a final time until all disks are selected. If you need to clear a disk, type its number a second time and press Enter.
    - If this installation is an overwrite installation, you can specify a supplemental disk by typing 66 and pressing the Enter key for the Devices not known to Base Operating System Installation option. This option opens a new menu that prompts for a device support media for the supplemental disk. The device-support media is only needed when the device cannot configure with the generic SCSI or bus-attached device drivers. BOS installation configures the system for the disk and then returns to the Change Disk window.
    - If this installation is an overwrite installation, you can specify to erase the disks chosen to be installed before the installation occurs by typing 55 and pressing the Enter key for the More Disk Options option. This option opens a new menu that prompts for the number of patterns to write, which is the number of times the drive is overwritten. If you choose 0 for the number of patterns to write, the disk is not erased before installation. This menu also prompts for the patterns to be used for each disk erasure. The patterns are a choice of the hexadecimal values 00, a5, 5a, or ff. For example, a pattern of 00 will write all zeros to the drive. Erasing a drive is a time consuming process and only drive types that are supported by the diag command can take advantage of this option (for example, erasure of IDE drives are not supported).
  2. When you select the disks, type 0 in the Choice field and press Enter. The Installation and Settings window displays with the selected disks listed under System Settings.
Change the primary language environment, if needed. Use the following steps to change the primary language used by this installation.
Note: Changes to the primary language environment do not take effect until after BOS is installed and your system is rebooted.
1. Type 2 in the Choice field on the Installation and Settings window to select the Primary Language Environment Settings option.
2. Select the appropriate set of cultural convention, language, and keyboard options. Most of the options are a predefined combination, however, you can define your own combination of options.
  - To select a predefined primary language environment, type that number in the Choice field and press Enter.
  - To configure your own primary language environment:
    1. Select MORE CHOICES.
    2. Page through the choices and select the Create Your Own Combination option.
    3. When the Set Primary Cultural Convention window displays, type the number in the Choice field that corresponds to the cultural convention of your choice and press Enter.
    4. When the Set Primary Language window displays, type the number in the Choice field that corresponds to your choice for the primary language and press Enter.
    5. When the Set Keyboard window displays, type the number in the Choice field that corresponds to the keyboard attached to the system and press Enter.
Change the installation options by typing 3 to change the Security Model or 4 to select More Options and press Enter. These options vary based on installation type (overwrite, preservation, or migration) and security choices. For more information about the installation options, see BOS installation options.
Change the installation edition by typing 5 to toggle through the choices, standard, enterprise, or enterprise_cloud. For more information about the installation options, see BOS installation options.
Verify your selections in the installation summary window and press Enter to begin the BOS installation process.

Your system automatically reboots after installation is complete. Go to Step 6. Finishing the BOS installation.
