HP-UX System Administrator's Guide: Routine Management Tasks

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.
Setting the PRI, HAA, and ALT Boot Paths Using the HP-UX setboot Command:
When you use setboot to configure the first (PRI), second (HAA), or third (ALT) item
in the boot options list, the new device path that you specify either replaces the original
boot option, or it is inserted in the original’s place (with the original item being shifted
toward the end of the boot options list):
□ If the boot option is currently not set to an HP-UX device, the new boot device
path is inserted as a new item in the boot options list.
In this case the original list item, if any, moves toward the end of the boot options
list and the new boot device path becomes the first (PRI), second (HAA), or third
(ALT) item in the list, as specified by setboot.
□ If the boot option is currently set to an HP-UX device and the list item has the
standard description (for example, “HP-UX Primary Boot for PRI” or “HP-UX
Alternate Boot for ALT”) then the new boot device path replaces the original
item in the boot options list.
□ If the boot option currently is set to an HP-UX device and the list item’s description
is not standard for its place in the boot options list, then the new boot device setting
is inserted as a new item in the boot options list.
In this case the original list item is moved toward the end of the boot options list.
