- create and modify resource pool configuration files
/usr/sbin/poolcfg -c command [-d | [filename]]
/usr/sbin/poolcfg -f command_file [-d | [filename]]
/usr/sbin/poolcfg -h
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 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 target host.
The following options are supported:
Specify command as an editing command. See USAGE.
Operate directly on the kernel state. No filename is allowed.
Take the commands from command_file. command_file consists of editing commands, one per line.
Display extended information about the syntax of editing commands.
A script consists of editing commands, one per line, of the following:
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.
Make an entity of the specified type and name.
Remove the specified entity.
Change the listed properties on the named entity.
Connect one or more resources to a pool, or replace one or more existing connections.
Transfer one or more discrete components to a resource .
Transfer a resource quantity from src to tgt.
Transfer a resource quantity to tgt from src.
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.
Change the name of an entity on the system to its new name.
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.
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.
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.
Machine level entity
Named collection of resource associations
Processor set resource
Takes one of two values true or false.
A 64–bit signed integer value.
A 64–bit unsigned integer value.
Strings are delimited by quotes ("), and support the character escape sequences defined in formats(5).
Scientific notation is not supported.
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

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 processor set pset2 in the kernel:
# poolcfg -dc 'transfer 2 from pset pset1 to pset2'
