Prior to cold-installing HP-UX 11i v3, perform these tasks:

  • Select an HP-UX Console (Itanium-based systems only), if appropriate.

  • Back up any configuration files you want to reinstall.

  • Make a recovery image of your system.

  • If you intend to use Ignite-UX to cold-install HP-UX 11i v3 on more than one system, update your Ignite-UX server. For more information, refer to the Ignite-UX Administration Guide at:

    http://docs.hp.com/en/oshpux11iv3.html

  • Locate source media and codewords.

Task 1: Selecting Your HP-UX Console for Itanium-based Systems

NOTE: This section does not apply to PA-RISC systems. If you are cold-installing on a PA-RISC system, you can skip this section and proceed to “Task 2: Backing Up Your Configuration Files”.

If you are using an Itanium-based system, HP-UX requires that you select the correct console via a firmware selection menu. If you have ordered a machine with HP-UX pre-installed, your console selections have been chosen for you, but you may want to change these default console selections. If you are already on the system console, then you can skip this section.

However, if you are cold-installing HP-UX or changing your system configuration, you may need to select the correct console. Skipping this step can result in HP-UX using an unexpected device as a console, which can appear as a system hang.

Depending on the firmware level of your Integrity server, you can select your primary HP-UX console using one the following methods:

  • conconfig command (if present)

  • Firmware Selection Menu

Do not select more than one console device. HP-UX 11i v3 recognizes only one device at a time. Choosing more than one device can result in the appearance of system hang.

Determining if the conconfig Command Exists on your System

  1. At the EFI prompt type the following command:

    Shell> conconfig

    • If the command exists, the system will return output similar to the following:

      CONSOLE CONFIGURATION
Index  Primary 	Type    	Device Path 1      P    			Serial
 	Acpi(HWP0002,PNP0A03,0)/Pci(1|2) 2      S    			VGA
     Acpi(HWP0002,PNP0A03,0)/Pci(4|0)

    • If the command does not exist, the system will return the error message: conconfig not found.

  2. Depending on whether the conconfig command exists on your system, use either the conconfig command or the Firmware Selection Menu to select your primary HP-UX console.

Using the conconfig Command to Select the Primary HP-UX Console

  1. Type conconfig at the command line. You will see output similar to the following: 

    CONSOLE CONFIGURATION
Index  Primary 	Type    	Device Path 1      P    			Serial
 	Acpi(HWP0002,PNP0A03,0)/Pci(1|2) 2      S    			VGA
     Acpi(HWP0002,PNP0A03,0)/Pci(4|0)

  2. Decide which console you want to use.

    Depending on your system configuration, HP-UX can use one of the following devices as your system console:

    • System Serial Port

    • Management Processor (MP) Serial Port (if present)

    • VGA device (if present)

  3. Use the conconfig command to select your primary console. For example, to select “system serial port” as your primary console, type the following at the command line:

    Shell> conconfig 1 primary

    For more information on the conconfig command, type the following at the EFI prompt:

    help conconfig

  4. Reboot your system.

Using the Firmware Selection Menu to Select the Primary HP-UX Console

  1. Decide what console you want to use.

    Depending on your system configuration, HP-UX can use one of the following devices as your system console:

    • System Serial Port

    • Management Processor (MP) Serial Port (if present)

    • VGA device (if present)

  2. Using the EFI menus, do the following:

    • Select Boot option maintenance from the main Boot Manager Menu.

    • Select Select Active Console Output Devices.

    • Select the correct output device and deselect others. On the HP Integrity rx2600 and the HP Integrity rx5670 systems, the Select Active Console Output Devices menu looks like this:

      EFI Boot Maintenance Manager
ver 1.10 [14.57] Select the Console Output Device(s)  Acpi(PNP0501,0)/Uart(9600
N81)/VenMsg(PcAnsi) Acpi(PNP0501,0)/Uart(9600 N81)/VenMsg(Vt100) Acpi(PNP0501,0)/Uart(9600
N81)/VenMsg(Vt100+) Acpi(PNP0501,0)/Uart(9600 N81)/VenMsg(VtUtf8)
Acpi(HWP0002,700)/Pci(1|1)/Uart(9600 N81)/VenMsg(PcAnsi) Acpi(HWP0002,700)/Pci(1|1)/Uart(9600
N81)/VenMsg(Vt100) Acpi(HWP0002,700)/Pci(1|1)/Uart(9600 N81)/VenMsg(Vt100+)
Acpi(HWP0002,700)/Pci(1|1)/Uart(9600 N81)/VenMsg(VtUtf8) * Acpi(HWP0002,700)/Pci(2|0)
Acpi(HWP0003,400)/Pci(0|0) Save Settings to NVRAM Exit

Understanding Interface Differences Between Itanium-based Systems

Each Itanium-based system has a similar interface with minor differences. You can navigate these menus with the arrow keys or “v” and “^” keys, and use the Enter or spacebar key to select and deselect devices. Selected devices have an asterisk (*) next to them. After making your changes to this menu, select Save Settings to NVRAM and then Exit.

VGA and Other Consoles Types

In the example menu shown above, the first four entries are identical except for their VenMsg section, meaning each entry is actually the same device, with different protocols for accessing the device. If the first entry is selected, use an ANSI-capable terminal device to communicate with the serial port. If the second entry is selected, use a VT100-capable terminal device, and so on.

If you select either a system or an MP serial port, HP recommends you choose a VT100-capable terminal device.

Serial port, Management Processor (MP) and VGA device paths can vary between each Itanium-based system. Please refer to the appropriate platform documentation for your product for information on determining the device paths.

Selecting a Console on the HP Integrity rx2600, rx5670 Systems

On the HP Integrity rx2600 and the HP Integrity rx5670 systems, an entry in the output device menu that has a Uart section and a Pci section is the serial port on a Management Processor (MP). To use the MP as your console device, select one of the MP serial device entries and deselect everything else.

  1. Select Select Active Console Input Devices.

  2. Select the correct input device and deselect others.

    For input devices, a device that has a Pci section in its path but does not have a Uart section is a USB keyboard device.

  3. Select Select Active Standard Error Device.

  4. Select the correct standard error device and deselect others.

    The device displays important firmware messages reporting errors.

  5. Select Save to NVRAM and then select Cold Reset to reset your system.

    A system reset is required for your console selections to take effect.

Additional Notes on Console Selection

  • HP-UX acts based upon the EFI Boot Maintenance Manager menu's Select Active Console sections to determine where to send its output. If the incorrect console devices are selected, HP-UX may either fail to boot or boot with output directed to the wrong location. Therefore, any time new potential console devices are added to a system, or anytime NVRAM on a system is cleared, review console selections to ensure that they are correct.

  • The EFI command, conconfig, may also be used to configure console devices. When using conconfig to select a console device, only one active console should be configured; otherwise, HP-UX may either fail to boot or boot with output directed to the wrong location.

  • You can find more information on the EFI Paths used for console selection in the Intel® Extensible Firmware Interface (EFI) documents available from the Intel Web site.

Task 2: Backing Up Your Configuration Files

If you plan to cold-install HP-UX 11i v3 on a system that already has HP-UX installed, make sure to save the files that you want to reinstall, such as:

  • Configuration files in /etc

  • The contents of /usr/local

  • Any local home directories (that is, those you do not import from another system)

  • Any configuration files located in the /etc/opt directories for installed software

If multiple users are preparing for the cold-install, you might consider creating a file system. Mount it with smh. Then create a subdirectory for each system or user (for example, /backup/your_sys).

As root, copy the files. For example:

  1. Copy all config files from /etc on a system named system1 to system system2. On system2, enter:

    mkdir /backup/system1/etc

    rcp -p your_name@system1:/etc/* /backup/system1/etc/

  2. Copy your local home directory to the backup system:

    mkdir /backup/system1/home

    rcp -pr your_name@system1:/home/ /backup/system1/home/

Task 3: Making a Recovery Image of Your System

Any data on the client disks that are used for installation, including the operating system, are removed entirely as part of this installation process. Make a recovery image of your system so you can easily restore it to its original state if a problem occurs. See “Backing Up Your System” for more information.

Task 4: Updating Your Ignite-UX Server

Ignite-UX supports network-based installations, which might be convenient when installing many systems. For more information, consult the Ignite-UX Administration Guide available at:

http://docs.hp.com/en/IUX/

Task 5: Locating Source Media and Codewords

Locate the source media needed for the cold-install. See “Locating Source Media and Codewords” for instructions.
