poolcfg(1M) System Administration Commands poolcfg(1M)NAMEpoolcfg - create and modify resource pool configuration files
SYNOPSIS
/usr/sbin/poolcfg -c command [-d | [filename]]
/usr/sbin/poolcfg -f command_file [-d | [filename]]
/usr/sbin/poolcfg -h
DESCRIPTION
The poolcfg utility provides configuration operations on pools and
sets. These operations are performed upon an existing configuration and
take the form of modifications to the specified configuration file. If
you use the -d option, the modifications occur to the kernel state.
Actual activation of the resulting configuration is achieved by way of
the pooladm(1M) utility.
Pools configuration files are structured files that must have been con‐
structed using poolcfg itself or libpool(3LIB) directly.
An invocation of poolcfg with the pool dynamic location and write per‐
mission will hang if the dynamic location has already been opened for
writing.
The configurations which are created by this utility can be used by
pooladm to instantiate the configuration upon a target host.
OPTIONS
The following options are supported:
-c command Specify command as an editing command. See USAGE.
-d Operate directly on the kernel state. No filename is
allowed.
-f command_file Take the commands from command_file. command_file
consists of editing commands, one per line.
-h Display extended information about the syntax of
editing commands.
USAGE
Scripts
A script consists of editing commands, one per line, of the following:
info [entity-name]
Display configuration (or specified portion) in human readable form
to standard output. If no entity is specified, system information
is displayed. Therefore, poolcfg-c 'info' afile is an equivalent
invocation to poolcfg-c 'info system name' afile.
create entity-name [property-list]
Make an entity of the specified type and name.
destroy entity-name
Remove the specified entity.
modify entity-name [property-list]
Change the listed properties on the named entity.
associate pool-name [resource-list]
Connect one or more resources to a pool, or replace one or more
existing connections.
transfer to [resourcetype] name[component-list]
Transfer one or more discrete components to a resource .
transfer [quantity] from [resourcetype] [src] to [tgt]
Transfer a resource quantity from src to tgt.
transfer [quantity] to [resourcetype] [tgt] from [src]
Transfer a resource quantity to tgt from src.
discover
Create a system entity, with one pool entity and resources to match
current system configuration. All discovered resources of each
resource type are recorded in the file, with the single pool refer‐
ring to the default resource for each resource type.
This command is a NO-OP when poolcfg operates directly on the ker‐
nel. See the -d option.
You should avoid use of this command. The preferred method for cre‐
ating a configuration is to export the dynamic configuration using
pooladm(1M) with the -s option.
rename entity-name to new-name
Change the name of an entity on the system to its new name.
Property Lists
The property list is specified by:
( proptype name = value [ ; proptype name = value ]* )
where the last definition in the sequence for a given proptype, name
pair is the one that holds. For property deletion, use ~ proptype name.
Resource Lists
A resource list is specified by:
( resourcetype name [ ; resourcetype name ]* )
where the last specification in the sequence for a resource is the one
that holds. There is no deletion syntax for resource lists.
Component Lists
A component list is specified by:
( componenttype name [ ; componenttype name ]* )
where the last specification in the sequence for a component is the one
that holds. There is no deletion syntax for component lists.
Recognized Entities
system Machine level entity
pool Named collection of resource associations
Resource Types
pset Processor set resource
Property Types
boolean Takes one of two values true or false.
int A 64-bit signed integer value.
uint A 64-bit unsigned integer value.
string Strings are delimited by quotes ("), and support the charac‐
ter escape sequences defined in formats(5).
float Scientific notation is not supported.
EXAMPLES
Example 1 Writing a poolcfg Script
The following poolcfg script creates a pool named Accounting, and a
processor set, small-1. The processor set is created first, then the
pool is created and associated with the set.
create pset small-1 ( uint pset.min = 1 ; uint pset.max = 4)
create pool Accounting
associate pool Accounting ( pset small-1 )
Example 2 Reporting on pool_0
The following command reports on pool_0 to standard output in human
readable form:
# poolcfg-c 'info pool pool_0' /etc/pooladm.conf
Example 3 Destroying pool_0 and Its Associations
The following command destroys pool_0 and associations, but not the
formerly associated resources:
# poolcfg-c 'destroy pool pool_0' /etc/pooladm.conf
Example 4 Displaying the Current Configuration
The following command displays the current configuration:
$ poolcfg-c 'info' /etc/pooladm.conf
system example_system
int system.version 1
boolean system.bind-default true
string system.comment Discovered by libpool
pool pool_default
boolean pool.default true
boolean pool.active true
int pool.importance 5
string pool.comment
string.pool.scheduler FSS
pset pset_default
pset pset_default
int pset.sys_id -1
string pset.units population
boolean pset.default true
uint pset.max 4294967295
uint pset.min 1
string pset.comment
boolean pset.escapable false
uint pset.load 0
uint pset.size 2
cpu
int cpu.sys_id 0
string cpu.comment
cpu
int cpu.sys_id 2

Example 5 Moving cpu with ID 2 to Processor Set pset1 in the Kernel
The following command moves cpu with ID 2 to processor set pset1 in the
kernel:
# poolcfg-dc 'transfer to pset pset1 ( cpu 2 )'
Example 6 Moving 2 cpus from Processor Set pset1 to Processor Set pset2
in the Kernel
The following command moves 2 cpus from processor set pset1 to proces‐
sor set pset2 in the kernel:
# poolcfg-dc 'transfer 2 from pset pset1 to pset2'
