Administering a System: Booting and Shutdown
Booting Systems
Chapter 5476
Delete Boot Option(s) Allows you to interactively delete one
or more entries from your boot
options list
Change Boot Order Allows you to reorder your boot
options list
Step 3. When the boot options list for your system is as you want it, select “Exit”
to return to the EFI Boot Manager’s main menu (which should now
reflect your new edits to the boot options list).
Changing the Contents of an AUTO File on a Boot Device
On an HP Integrity Server, during an automatic boot (and some manual
boots), the file \EFI\HPUX\AUTO on the device you are booting from is
used to locate the kernel file to boot from.
Typically the contents of the AUTO file are “boot vmunix”. You can
temporarily override the contents of the AUTO file, for example to boot
from an alternate kernel file (see “Booting from an Alternate Kernel File”
on page 472), but if you want to boot from the other kernel file by default,
or want to regularly use certain boot options, you need to change the
contents of the AUTO file to reflect the appropriate settings.
NOTE The AUTO file can only specify the boot command. To issue other
hpux.efi loader commands, you must interact directly with the loader.
There are three basic ways to change the contents of the AUTO file on a
device. Two of these can only be accomplished using the pre-boot EFI
environment. The third can be accomplished while HP-UX is running.
• Changing the AUTO file from the EFI Shell (pre-boot)
• Changing AUTO from the HPUX.EFI Boot Loader (pre-boot)
• Changing AUTO from a Running HP-UX Environment
Changing the AUTO file from the EFI Shell (pre-boot)
This procedure cannot be done from a running HP-UX system. It
assumes that your system has not yet been booted. If you need to change
the contents of a device’s AUTO file while HP-UX is running, see
“Changing AUTO from a Running HP-UX Environment” on page 481.
