hpux.efi(1M) hpux.efi(1M) NAME
hpux.efi - HP-UX bootstrap for Itanium-based systems SYNOPSIS
DESCRIPTION
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. supports the following options: Display the release and version numbers of the utility. 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 kernel configuration, and boot with known good settings instead. 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) file. Load a kernel object file from an HP-UX file system and transfer control to the loaded image. (Note, the operation is position-dependent). Currently, is limited to disk for booting. file can be the name of a kernel object file or the name of a kernel configuration direc- tory. The following commands can given interactively from the keyboard only after is launched. List the contents of HP-UX directories in detail. List the contents of HP-UX directories. Display the contents of the file. Change the contents of the file to string. boot Operation The operation loads an ELF kernel object file from supported HP-UX file system (HFS, VxFS). It then transfers control to the loaded image. In addition to the kernel object file, also loads persistent system-specific files from the directory and kernel configuration-specific files from the directory during operation. always assumes (the boot directory) as the current directory. For example, would actually yield: Along with this information, gives the sizes of the and segments before transferring control to it. The operation accepts several options. Note that options be specified positionally as shown in the syntax statement in the Options for the operations are as follows: Set the initial run-level for when booting the system. This run-level overrides any run-level specified in an entry in See init(1M) and inittab(4). variable=value Set the specified variable to the specified value. (No whitespace is allowed.) If variable is a kernel tunable parameter, this sets the value of that tunable, overriding the value in the kernel con- figuration being booted. value must be a decimal integer or a hexadecimal integer (with a prefix). can load only ELF object files. ll and ls Operations The and operations list the contents of the HP-UX directory. In addition to filenames, displays size and date information when used on supported HP-UX filesystems. For VxVM disks, only boot volume information can be displayed. To display boot volume information, either a relative path to or an abso- lute path can be used. setauto Operation The operation overwrites the contents of the file, with the string specified. showauto Operation The operation displays the contents of the file, See in the section. EXAMPLES
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 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 is launched. The EFI gives the user the option to automatically start any EFI appli- cation. After is launched by the EFI it looks for an file and uses its content for the boot string. Then it gives the user the option to override the sequence by pressing any key: If does not detect a key press, it initiates the sequence using the string. displays messages similar to the following on the console: If successfully locates the kernel object file, it displays the progress of loading each sections and the symbol table of the object file. Then it displays the progress of loading system- and kernel configuration-specific directories. Finally, displays the complete path to the kernel object file loaded and the size, size, and size of the load image before control is passed to the image. The loaded image then displays numerous configuration and status messages. Interactive Boot To use interactively, the user must interrupt the autoboot sequence by pressing a key or removing the file. Then interactively prompts for commands. SEE ALSO
