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

Adding vPars adds the vPars Monitor layer, so now hpux(for Integrity, hpux.efi) loads the
vPars Monitor. Then the vPars Monitor boots the kernels of the virtual partitions. The boot
sequence becomes the following.
(firmware)
1. ISL or EFI
2. hpux or hpux.efi
(vPars Monitor and partition database)3. /stand/vpmon
(kernels of the virtual partitions)4. /stand/vmunix
Boot Sequence: The Details
With or without vPars, the firmware loads and launches ISL or EFI.
IntegrityPA-RISC
Shell> fs0:
fs0:\> \efi\hpux\hpux.efi
ISL>
In a server without vPars, from ISL or EFI, the loader hpux or hpux.efi loads the kernel
/stand/vmunix:
IntegrityPA-RISC
HPUX> boot vmunixISL> hpux /stand/vmunix
However, in a server with vPars, from the loader (hpux or hpux.efi) loads the vPars
Monitor (/stand/vpmon):
IntegrityPA-RISC
HPUX> boot vpmonISL> hpux /stand/vpmon
The vPars Monitor loads the partition database (the default is /stand/vpdb) from the same
disk that /stand/vpmon was booted. The vPars Monitor internally creates (but does not boot)
each virtual partition according to the resource assignments in the partition database.
Next, the vPars Monitor runs in interactive mode (when no options to /stand/vpmon are given)
with a command line interface.
MON>
To boot a kernel in a virtual partition (that is, to launch a virtual partition), use the vPars Monitor
command vparload. For example, to launch the virtual partition named uma1:
MON> vparload -p uma1
In this example, the vPars Monitor would load the virtual partition uma1 and launch the kernel
from the boot device specified for uma1. (The boot device is assigned when the virtual partition
is created and is recorded in the vPars Monitor database.)
HP-UX is now booted on the virtual partition uma1.
Once a virtual partition is running, you will be at the virtual console of a virtual partition.
Subsequent virtual partitions can be booted using the vPars command vparboot at the HP-UX
shell prompt of uma1. For information on how to boot a virtual partition, see “Booting a Virtual
Partition” (page 158).
