HP-UX Virtual Partitions Administrator Guide (includes A.05.07) (5900-1229, September 2010)

new EFI device path. However, firmware-saved EFI boot path options are not updated. If
the nPartition or vPars Monitor is rebooted, the new EFI boot path options are discarded
and replaced with the previously saved EFI boot path options, which contain now stale EFI
device paths.
The EFI boot options can be updated manually by performing the following:
1. Switch to nPars mode via the vparenv or vparconfig command.
2. Reboot the nPartition to the EFI Boot Manager.
3. Select Boot Option Maintenance Menu.
4. Select Delete Boot Option(s).
5. Select HP-UX Primary Boot and then exit.
6. Select Exit to return to the EFI Boot Manager.
7. Select EFI Shell [Built-in].
8. Launch HP-UX from the EFI shell prompt:
Shell> fsN:
fsN:\> efi\hpux\hpux boot vmunix
9. Use the setboot command to set up the primary boot path with the desired boot
device. This also sets the HP-UX Primary Boot boot option with the latest EFI device
path.
10. Use the vparenv command to switch to vPars mode.
11. Reboot the nPartition.
• EFI Command default clear Whenever you use the default clear command at
the EFI shell, this erases vPars information that is stored in NVRAM and the vPars monitor
may not boot. To boot the vPars Monitor, you should perform the following:
1. Change the mode to nPars and allow the system to reboot to the EFI shell:
Shell> fsN:
fsN:\> efi\hpux\vparconfig reboot nPars
2. At the EFI prompt, boot the HP-UX kernel in standalone mode:
Shell> fsN:
fsN:\> efi\hpux\hpux /stand/vmunix
The booting of the kernel will restore the vPars information in NVRAM. Now you can
return to vPars mode and reboot the vPars Monitor.
3. To change the mode to vPars and reboot the vPars Monitor:
# vparenv -m vPars
# shutdown -r
...
Shell> fs0:
fs0:\> \efi\hpux\hpux vpmon
Integrity Differences Relative to PA-RISC
Beginning with vPars A.04.01, vPars is supported on both Integrity and PA-RISC platforms. This
section describes the major conceptual differences for booting and running vPars on Integrity
relative to the original vPars on PA-RISC.
Booting
• Modes On Integrity platforms, you have to set the mode (vPars or nPars) to be able to
boot the nPartition into standalone (nPars) or the vPars environment (vPars).
See “Modes: Switching between nPars and vPars Modes (Integrity Only)” (page 126).
