Virtual Partitions Command Summary

There are several commands used to create and work with Virtual Partitions. A table in the vPars book as well as a tear-out card provide an overview of many commonly used Virtual Partitions-related commands. Table 1-1 is an abbreviated version of command summary:

Table 1-1 Virtual Partition Commands

Command

Description

ISL>

Initial System Load prompt.

Virtual Partitions Monitor is loaded from ISL> with:

ISL> hpux /stand/vpmon

MON>

To load Virtual Partitions directly from ISL>, use:

ISL> hpux /stand/vpmon vparload -p vPar_name

MON>

Virtual Partitions Monitor prompt. (Also see vparload command.)

This is loaded from ISL with:

ISL> hpux /stand/vpmon

MON>

To load an alternate database from ISL, use:

ISL> hpux /stand/vpmon -D db_file

To load one vPar from MON , use:

MON> vparload vPar_name

Many other commands can be issued from MON. Type help or ? to list.

(Commands include: scan, vparinfo, ls, log, getauto, lifls, cbuf, cat.)

vparload

Load Virtual Partitions from MON> prompt only.

To boot a Virtual Partition from MON>:

MON> vparload -p vPar_name

vparboot

Boot a Virtual Partition from the command line only.

To boot a Virtual Partition from the command line:

# vparboot -p vPar_name

vparcreate

Create a Virtual Partition.

To create a Virtual Partition with three processors (num) total, two bound (min) , 2048MB RAM, all components on 0/0, boot disk at 0/0/1/1.2.0, with a kernel of /stand/vmunix, autoboot on, and console at 0/0/4/0:

# vparcreate -p vPar_name -a cpu::3 -a cpu:::2:4

-a mem::2048 -a io:0/0 -a io:0/0/1/1.2.0:boot

-b /stand/vmunix -B auto

vparmodify

Modify the attributes of a Virtual Partition.

To add processor at path 109 (adds this proc to those already assigned):

# vparmodify -p vPar_name -a cpu:109

vparremove

Delete a Virtual Partition.

To delete a Virtual Partition in the currently running database:

# vparremove -p vPar_name

vparreset

Reset a Virtual Partition.

To reset a Virtual Partition without TOC (t), hard (h), bypassing display of PIM data (q), or forcing (f):

# vparreset -p vPar_name

vparresources(5) man page

Provides description of Virtual Partitions and their resources.

This is a manual page that describes Virtual Partition resources in general and how resources are specified in other commands, such as vparmodify.

vparstatus

Display the status of Virtual Partitions.

To display the status of a Virtual Partition in verbose mode:

# vparstatus -v -p vPar_name

vpartition man page

Display information about the Virtual Partition Command Line Interface.

Provides the following brief description of Virtual Partitions commands:

vparboot Boot (start) a virtual partition.

vparcreate Create a new virtual partition.

vparmodify Modify an existing virtual partition.

vparremove Remove (delete) an existing virtual partition.

vparreset Simulate a TOC or hard reset to a virtual partition.

vparstatus Display virtual partition and available resources information.

Specify CPU Resources by:

Number of bound and unbound CPUs: cpu::num

CPU hardware path(s): cpu:path

Minimum and maximum number: cpu:::[min][:[max]]

Specify Memory by:

Size mem::size

Base and range: mem:::base:range

combination of both above.

Specify I/O:

Use path: io:path[:attr1[,attr2[...]]]

(see man page vparresources for details).

To add resources use: (This adds component relative to what already exists if running vparmodify.)

-a cpu:path

-a cpu::num (can be done with vPar running)

[-a cpu::num] [-a cpu:::[min]:[max]] -[a cpu:path] (::: is vparcreate only)

-a io:path[:attr1[,attr2[...]]

-a mem::size

-a mem:::base:range

To delete resources use (This deletes component relative to what already exists if running vparmodify.)

-d cpu:path

-d cpu::num (can be done with vPar running)

-d io:path[:attr1[,attr2[...]]

-d mem::size

-d mem:::base:range

To modify resources use: (This modifies to absolute number rather than relative.)

-m cpu::num (can be done with vPar running)

-m cpu:::[min][:max]]

-m io:path[:attr1[,attr2[...]]

-m mem::size

vPars setboot Options:

-a

-b

-p

-s

no options

Changes the alternate boot path of the Virtual Partition.

Sets the autoboot attribute of the Virtual Partition.

Changes the primary boot path of the Virtual Partition.

No effect.

Displays information about boot attributes.

To set Autoboot on:

# setboot -b on

vPars States:

load

boot

up

shut

down

crash

hung

The kernel image of a Virtual Partition is being loaded into memory. This is done by the Virtual Partition monitor.

The Virtual Partition is in the process of booting. The kernel image has been successfully loaded by the Virtual Partition monitor.

The Virtual Partition has been successfully booted and is running.

The Virtual Partition is in the process of shutting down.

The Virtual Partition is not running and is down.

The Virtual Partition has experienced a panic and is crashing.

The Virtual Partition is not responding and is hung.


We'll use some of the commands shown in Table 1-1 in the upcoming section on creating virtual partitions. There is more detail on the Virtual Partition commands in Appendix A, which contains the online manual pages for the commands.

Let's now move on to creating our virtual partitions.
