Cold-Install Tasks

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.
Back up your system using any supported HP-UX backup software.
If you intend to use Ignite-UX to cold-install HP-UX 11i v3 on more than one system, update your Ignite-UX server.
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.

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.

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)

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.

Select Select Active Console Input Devices.
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.
Select Select Active Standard Error Device.
Select the correct standard error device and deselect others.
The device displays important firmware messages reporting errors.
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

I f 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:

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/
Copy your local home directory to the backup system:
mkdir /backup/system1/home rcp -pr your_name@system1:/home/ /backup/system1/home/

Task 3: Backing Up Your System

Back up your system before performing a cold-install, and again after the cold-install is complete. If a problem occurs, you can easily restore the system to its original state. See “Backing Up Your System” for more information.

Task 4: Updating Your Ignite-UX Server

If you intend to use the Ignite-UX server to cold-install HP-UX 11i v3 on more than one system, update your Ignite-UX server first.

The HP-UX 11i v3 DVD contains the complete Ignite-UX product. When you cold-install HP-UX 11i v3 from the media, a subset of Ignite-UX is used to perform the installation on a single system. Updating your Ignite-UX server and using it to update other systems ensures that:

You keep consistent kernel configuration with specific drivers, daemons, and kernel tunables on all systems.
You have the following commands to create an operating system recovery image: make_net_recovery and make_tape_recovery. Refer to the make_net_recovery(1M) and make_tape_recovery(1M) manpages for information.

For information on updating your Ignite-UX server, download the latest Ignite-UX software and documentation from the Ignite-UX Web site:

Task 5: Locating Source Media and Codewords

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