NAME
auto_adm - manage LIF AUTO configuration files
DESCRIPTION
auto_adm files occur in two different formats,
auto_conf (CONF) and Initial System Loader (ISL)
format. The auto_adm (1M) utility is used to manipulate these files, and to convert between formats.
Information contained in an
auto_adm file is used during the boot up process to offer the user a set of
boot options, and to direct the ISL
and Secondary System Loader (SSL) to execute the desired boot
sequence.
CONF Format
The
CONF format is intended to be human readable, and consists of two classes of information: global
and image specific. The global information specifies the following keyword =value pairs:
timeout =NN
Wait NN seconds until executing the default boot action. 0 (Zero) means wait indefinitely.
message=string
A string containing the prompt displayed to to the user on the console during boot up, for example,
"Choose Operating System to Install." The string need not be enclosed in quotes.
default =MM
The default image to boot after the timeout expires or user presses "Enter".
The image-specific portion of the
CONF file consists of one or more sets of four keyword =value pairs
describing a boot image action.
label =string
A string label that will be displayed to the user on the console describing what action will be per-
formed if this boot image is loaded. For example, "Install 64-bit HP-UX B.11.11" The string need
not be enclosed in quotes.
bootcmd =cmd
The SSL command to be executed if this image is selected. See hpux (1M) for more information.
boot =hwpath
The hardware path relative to the boot LIF containing the desired boot image. Typically
(;0). See
hpux(1M) for more information.
image=path
The path of the image to be booted relative to the hardware path specified in the boot directive.
An example
CONF-format auto_adm file is:
timeout = 0 # wait indefinitely
message = Choose version to install # prompt to user
default = 2 # choose 64-bit by default
label = B.11.11 32bit install
bootcmd = boot
boot = (;0)
image = boot/Rel_B.11.11/INSTALL # path to 32-bit install kernel
label = B.11.11 64bit install
bootcmd = boot
boot = (;0)
image = boot/Rel_B.11.11/WINSTALL # path to 64-bit install kernel
ISL Format
The
ISL format is the file format actually written into the boot LIF by auto_adm, assembled from one
or more CONF-formatted files.
Like the
CONF format, ISL formatted files consist of a global section and an image-specific section.
The global section consists of a single line:
hpux KernelPrompt message timeout default
