ISL booting hpux
Boot
: disk(0/0/1/0/0.15.0.0.0.0.0;0)/stand/vmunix
To boot an HP-UX kernel other than that which is pointed to in the AUTO
file, or to boot HP-UX in single-user or LVM-maintenance mode, stop at
the ISL prompt and specify the appropriate arguments to the hpux
loader.
Specify the HP-UX path name of the alternate kernel file that you want
to boot as part of the devicefile argument in the hpux boot command.
For example:
ISL> hpux boot disk(2/4.0.0;0)/stand/ alt_kernel_file_name
Changing the Contents of the Autoexecute File
On HP 9000 systems

, an important part of what makes an automatic
boot possible is a file known as an autoexecute file that contains the
command that you normally use to boot the HP-UX operating system
(the hpux command that you would enter at the ISL> prompt). The
contents of this file are used during the boot process when some or all of
the hpux command elements have been omitted from the command given
to ISL, as in the case of automatic booting.
The autoexecute file is not located in any HP-UX file system because its
contents are needed before HP-UX is running (before HP-UX can access
its file systems). Instead, the autoexecute file, called AUTO, is located in
the LIF area (sometimes called the boot area) on one of your bootable
disks. This is the area is where ISL itself resides.
1. On V-class systems, the function of the autoexecute file is served
by a variety of defined system values, set through various
boot-mode commands.
