NAME

vpmon - vPars Monitor Management or Information Lookup Commands

SYNOPSIS

vpmon [-a][-i][

-D database_ﬁlename][vPars Monitor Management Commands]

Platform Support Remarks

vpmon is not supported on systems with Onboard Administrator (OA) based partition management.

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 Moni-

tor (

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 par-

titions. 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 Itanium-based plat-

forms. 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 command 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 Itanium-based platforms:

HPUX> boot /stand/vmunix

In a system with vPars installed, vpmon is loaded as follows:

For PA-RISC platforms:

ISL> hpux /stand/vpmon

For Itanium-based 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 par-

tition database ﬁle is /stand/vpdb.

vPars Monitor Commands

See the vPars Monitor Commands section for information about the

vpmon commands for

vPars monitor management and vPars monitor information lookup.

vpmon(5) vpmon(5) This option is available on Itanium-based platforms only. It is mutually exclusive with the -b, -B, and -D options. This option is provided as a tool to boot a vPar only if a valid HP-UX h/w path to EFI path mapping is not present in the virtual partition database for a boot disk. Refer to vparefiutil (1M) for additional information on HP-UX h/w path to EFI path mappings. This option is not recommended for general purpose use.

vpmon(5) vpmon(5) restricted to modifying only its own resources and attributes. A non Designated-Admin vPar cannot create, boot, reset, modify, or remove another vPar. The monadmin command may be invoked with one of the following mutually-exclusive options: -S on Enables the virtual partition flexible administrative capability and allows the MP user of an nPartition to set a new virtual partition flexible administrative password. By default, all existing partitions are not Designated-Admin vPars.

vpmon(5) vpmon(5) This command is applicable for PA-RISC platforms only. log The log command can be used to view the event log. ls [-a|-l|-n|-i|-F|-H] [directory_name] The ls command is similar to the HP-UX ls command. However, only one target directory may be given. If more than one directory is given, the contents of the last directory are listed. If no target directory is given, the contents of the current directory (for example, the /stand directory) are listed.
