hpux.efi - HP-UX bootstrap for Itanium-based systems
SYNOPSIS [Toc] [Back]
hpux.efi [-V] [-tm] [-vm]
DESCRIPTION [Toc] [Back]
hpux.efi is the HP-UX-specific operating system loader utility for
bootstrap. It is a native efi(4) application that can be run on the
Itanium-based platform.
hpux.efi supports the following options:
-V Display the release and version numbers of the hpux
utility.
-tm Boot the system in tunable maintenance mode, also
known as "failsafe boot" mode. This option will
disregard the tunable settings and module settings
in the kenrel configuration, and boot with known
good settings instead.
-vm Boot the system in VxVM maintenance mode, configure
only the root volume, and then enter single user
mode.
The following commands can be given interactively from the keyboard or
provided in an efi(4) AUTO file.
boot [file] Load a kernel object file from an HP-UX file system
and transfer control to the loaded image. (Note,
the boot operation is position-dependent).
Currently, hpux.efi is limited to disk for booting.
file can be the name of a kernel object file or the
name of a kernel configuration directory.
The following commands can given interactively from the keyboard only
after hpux is launched.
ll List the contents of HP-UX directories in detail.
ls List the contents of HP-UX directories.
showauto Display the contents of the AUTO file.
setauto string Change the contents of the AUTO file to string.
boot Operation
The boot operation loads an ELF kernel object file from supported HPUX
file system (HFS, VxFS). It then transfers control to the loaded

image.
In addition to the kernel object file, hpux.efi also loads persistent
system-specific files from the boot.sys directory and kernel
configuration-specific files from the configname/bootfs directory
during boot operation.
hpux.efi always assumes /stand (the boot directory) as the current
directory. For example, myconfig/vmunix would actually yield:
/stand/myconfig/vmunix
Along with this information, boot gives the sizes of the TEXT, DATA,
and BSS segments before transferring control to it.
The boot operation accepts several options. Note that boot options
must be specified positionally as shown in the syntax statement in the
SYNOPSIS. Options for the boot operations are as follows:
-irun-level Set the initial run-level for init when booting the
system. This run-level overrides any run-level
specified in an initdefault entry in /etc/inittab.
See init(1M) and inittab(4).
boot can load only ELF object files.
ll and ls Operations
The ll and ls operations list the contents of the HP-UX directory. In
addition to filenames, ll displays size and date information when used
on supported HP-UX filesystems.
For VxVM disks, only boot volume (/stand) information can be
displayed. To display boot volume information, either a relative path
to /stand or an absolute path can be used.
setauto Operation
The setauto operation overwrites the contents of the autoexec file,
AUTO, with the string specified.
showauto Operation
The showauto operation displays the contents of the autoexec file,
AUTO. See autoexecute in the EXAMPLES section.
EXAMPLES [Toc] [Back]
Automatic Boot
This is an overview of HP-UX automatic boot processes on Itanium-based
systems. When power is applied to the HP-UX system processor, or the
system Reset button is pressed, Itanium-based system firmware code is
executed to verify hardware and general system integrity (see
boot(1M)). After initializing the hardware, the EFI boot_manager is
launched. The EFI boot_manager gives the user the option to

automatically start any EFI application. After hpux.efi is launched
by the EFI boot_manager, it looks for an AUTO file and uses its
content for the boot string. Then it gives the user the option to
override the autoboot sequence by pressing any key:
*** HP-UX Boot Loader for IA-64 ***
*** Version #.# ***
*** Type 'help' for help ***
Press Any Key to interrupt Autoboot [Toc] [Back]
AUTO ==> boot vmunix -is

If hpux.efi does not detect a key press, it initiates the autoboot
sequence using the AUTO string. hpux.efi displays messages similar to
the following on the console:
AUTOBOOTING... [Toc] [Back]
AUTO BOOT> boot vmunix -is
If hpux.efi successfully locates the kernel object file, it displays
the progress of loading each sections and the symbol table of the
object file.
loading section 0
....................
loading section 1
......

Then it displays the progress of loading system- and kernel
configuration-specific directories.
Loading System Directory(boot.sys) to MFS [Toc] [Back]
....
Loading Kernel Boot Directory(bootfs) to MFS
......
Finally, boot displays the complete path to the kernel object file
loaded and the TEXT size, DATA size, and BSS size of the load image
before control is passed to the image.
Launching /stand/vmunix...
SIZE: Text:16308K + Data:1268K + BSS:2004K = Total:19581K
The loaded image then displays numerous configuration and status
messages.
Interactive Boot [Toc] [Back]

interactively prompts for commands.
