System Administration Commands poolcfg(1M)
NAME
poolcfg - create and modify resource pool configuration
files
SYNOPSIS
/usr/sbin/poolcfg -c command [-d [filename]
/usr/sbin/poolcfg -f commandfile [-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 activa-
tion of the resulting configuration is achieved by way of
the pooladm(1M) utility.
Pools configuration files are structured files that must
have been constructed using poolcfg itself or libpool(3LIB)
directly.
An invocation of poolcfg with the pool dynamic location and
write permission 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 tar-
get 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 commandfile Take the commands from commandfile.
commandfile consists of editing com-
mands, one per line.

System Administration Commands poolcfg(1M)
-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 speci-
fied, 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.

System Administration Commands poolcfg(1M)
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 referring to the
default resource for each resource type.
This command is a NO-OP when poolcfg operates directly
on the kernel. See the -d option.
You should avoid use of this command. The preferred
method for creating 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 prop-
type, name pair is the one that holds. For property dele-
tion, 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 com-
ponent 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 character escape sequences defined in for-
mats(5).
float Scientific notation is not supported.
EXAMPLES
Example 1 Writing a poolcfg Script
The following poolcfg script creates a pool named Account-
ing, 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 pool0

System Administration Commands poolcfg(1M)
The following command reports on pool0 to standard output
in human readable form:
# poolcfg -c 'info pool pool0' /etc/pooladm.conf
Example 3 Destroying pool0 and Its Associations
The following command destroys pool0 and associations, but
not the formerly associated resources:
# poolcfg -c 'destroy pool pool0' /etc/pooladm.conf
Example 4 Displaying the Current Configuration
The following command displays the current configuration:
$ poolcfg -c 'info' /etc/pooladm.conf

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 Proces-
sor Set pset2 in the Kernel
The following command moves 2 cpus from processor set pset1
to processor set pset2 in the kernel:
# poolcfg -dc 'transfer 2 from pset pset1 to pset2'
