NAME
vpmon - vPars monitor management or information lookup commands
SYNOPSIS
vpmon [-a][-i][
-D database_filename ][vPars Monitor Management Commands]
DESCRIPTION
The vPars (Virtual Partitions) product allows a user with superuser or with DEVOPS privilege to divide
hardware resources on a supported whole system or a single hard partition (nPartition) into one or more
virtual partitions. This is accomplished through a software layer called the Virtual Partition Monitor
(
vpmon) that logically resides between the operating system and the firmware.
The vpmon controls the management of the hardware resources and their assignment to the virtual parti-
tions. To be operational, each partition must contain at least one CPU, a boot hard disk, and enough
memory to run HP-UX. At least one PCI slot is required if an external LAN connection is needed. Each
partition will run its own copy of the operating system, providing software fault and namespace isolation.
User-specified partition information is stored in a file called the Virtual Partition database (default is
/stand/vpdb ). This information is read by the
vpmon during boot.
There are several arguments that may be passed to the
vpmon when it is booted from the Initial System
Loader (ISL) prompt on PA-RISC platforms or booted from the HPUX prompt on Integrity platforms.
Depending on the arguments, vpmon can either enter the interactive mode, indicated by the MON>
prompt, or continue with loading the virtual partitions. This MON> prompt is also called the vpmon com-
mand prompt.
Any options entered after vPars Monitor Management Commands at the ISL prompt will be treated as
arguments to the vPars monitor management commands.
Booting the vPars Monitor
In a system without vPars installed,
vmunix (the file containing the HP-UX kernel to be booted) is loaded
as follows:
For PA-RISC platforms:
ISL> hpux /stand/vmunix
For Integrity platforms:
HPUX> boot /stand/vmunix
With vPars installed, vpmon is loaded as follows:
For PA-RISC platforms:
ISL> hpux /stand/vpmon
For Integrity platforms:
HPUX> boot /stand/vpmon
Options
vpmon may be invoked with the following arguments:
-a Boots all virtual partitions that have the autoboot attribute set.
-i Causes the vpmon to enter into interactive mode. The interactive mode is the default
when no options are given. The interactive mode will also occur without the -i
option if none of the virtual partitions that are active are assigned the system boot
processor, if no virtual partitions are specified, or if no valid partition database is
found.
-D database_filename
Boots the virtual partitions configured in an alternate partition database file. The
default partition database file is /stand/vpdb .
vPars Monitor Commands
The commands that may be issued from the vpmon command prompt are classified as either vPars monitor
management commands or vPars monitor information lookup commands.
