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.
