3. Make sure the selected boot device is the one that contains the kernel file from
which you want to boot. If you are not sure:
a. Enter map at the EFI shell prompt to list bootable devices on your system.
The devices will be listed with entries that begin with fs#: (where # is a
number such as 0, 1, 2, 3, etc.). For example:
fs0 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part1,Sig88F40A3A-B992-11E1-8002-D6217B60E588)
fs1 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part3,Sig88F40A9E-B992-11E1-8004-D6217B60E588)
blk0 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)
blk1 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part1,Sig88f40A3A-B992-11E1-8002-D6217B60E588)
blk2 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part1,Sig88f40A6C-B992-11E1-8003-D6217B60E588)
blk4 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Secondary,Master)
b. Determine which entry maps to the device containing the kernel file you are
trying to boot from, and enter the fs#: name at the shell prompt.
For example, if the entry for the device from which you want to boot is tagged
as “fs7:”, enter fs7: at the shell prompt:
Shell> fs7:
The device associated with entry fs7: is now the selected boot device.
4. Enter the command hpux at the shell prompt and be prepared to stop the autoboot
sequence (again by hitting any key on the console keyboard) if you see a countdown
timer showing that an autoboot is about to commence.
NOTE: If the AUTO file on the now selected boot device will cause the system to
boot from the alternate kernel file you are trying to use, there is no need to interrupt
this second autoboot sequence. Otherwise, stop the automatic boot.
5. If you stopped the automatic boot in the previous step you should now be in the
HP-UX boot loader; the prompt should now be “HPUX>”.
At the boot loader prompt, enter the command boot filename where filename
is the name of the kernel file from which you are trying to boot.
Example 2-7 Booting from an alternate kernel file called “testvmunix”
HPUX> boot testvmunix
Changing the PRI, HAA, and ALT Boot Paths
On HP Integrity Servers, the primary, high-availability alternate, and alternate boot
paths are based on the first, second, and third items that appear in the boot options list
for the server, respectively.
You can manage the boot paths using the setboot command when HP-UX is running,
or by using the “Boot Option Maintenance Menu” in the EFI Boot Manager.
