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.
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 (http://docs.hp.com/en/oshpux11iv3.html#Ignite-UX).
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 console selection menu or EFI. (If you are already on the system console, then you can skip this section.) Even if you have ordered a machine with HP-UX pre-installed, you will want to choose your console, despite the factory defaults.

If you are cold-installing HP-UX or changing your system configuration, you will 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:

The EFI conconfig command (if present)
The EFI Boot Manager




	IMPORTANT: 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 a system hang.

Determining if the conconfig Command Exists on your System

At the EFI prompt type the following command:

Shell> conconfig

If the command exists, the system may 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)




	NOTE: The above is an example of factory defaults. As you will see later in these steps, one of these devices will have to be configured as “primary” (P); the other will have to be configured with a status of “Not Configured” (NC).

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

Depending on whether the conconfig command exists on your system, use either the conconfig command or the EFI Boot Manager to select your primary HP-UX console.

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

Enter conconfig at the command line. You may see output similar to the following:
CONSOLE CONFIGURATION Index Primary Type Device Path 1 P Serial Acpi(HWP0002,PNP0A03,0)/Pci(1|2) 2 NC VGA Acpi(HWP0002,PNP0A03,0)/Pci(4|0)
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 (if present)
- iLO (MP) Serial Port
- VGA device (MP/iLO)
Use the conconfig command to select your primary console. For example, to select “system serial port” as your primary console, enter the following at the command line:
Shell> conconfig 1 primary
Next, use the conconfig to deselect all other consoles so that only one console is marked P and all others are marked NC. For example, if your conconfig output looks like 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)
Enter:
Shell> conconfig 2 off
Now your conconfig output should look like this:
CONSOLE CONFIGURATION Index Primary Type Device Path 1 P Serial Acpi(HWP0002,PNP0A03,0)/Pci(1|2) 2 NC VGA Acpi(HWP0002,PNP0A03,0)/Pci(4|0)
Note that the unwanted VGA device in line 2 has the status of NC and the primary console in line 1 has the status of P.
Reboot your system.




	TIP: For more information on the conconfig command, enter the following at the EFI prompt: help conconfig

Using the EFI Boot Manager to Select the Primary HP-UX Console

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 (if present)
- iLO (MP) Serial Port
- VGA device (MP/iLO)

Using the EFI menu, do the following:

Open the EFI Boot Manager and select Boot Configuration, as in the following:
On the Boot Configuration screen, choose Console Configuration, as in the following:

On the Console Configuration screen, select one device as your system console. The device you have selected should have a status of P; all others should have a status of NC.




	NOTE: The following figure shows consoles with a primary (P) status and secondary (S) status. This would not be correct for your configuration. You should select only one device for a P status. The rest should be given an NC status. Only one active console should be configured; otherwise, HP-UX may either fail to boot or boot with output directed to the wrong location.

Understanding Interface Differences Between Itanium-based Systems

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

Serial port, MP/iLO 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.

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 website.

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:

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: 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, see the Ignite-UX Administration Guide (http://docs.hp.com/en/oshpux11iv3.html#Ignite-UX).

Task 5: Locating Source Media and Codewords

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