HP-UX Virtual Partitions Administrator Guide (includes A.05.08) (5900-1312, March 2011)
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 124).
On PA-RISC, you do not need to set modes.
• vparboot -I and the LAN Card
On Integrity platforms, performing a vparboot -I uses the LAN card of the target partition
to obtain the bootable kernel.
See “Ignite-UX, the LAN, the LAN card, and vparboot -I” (page 76).
