poolcfg(1M)
NAME
poolcfg - create and modify resource pool configuration
files
SYNOPSIS
/usr/sbin/poolcfg -c command filename
/usr/sbin/poolcfg -f command_file filename
/usr/sbin/poolcfg -h
DESCRIPTION
The poolcfg command 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. The special discover com-
mand does not require an existing configuration. Actual
activation of the resulting configuration is achieved by way
of the pooladm(1M) command.
Pools configuration files are structured files that must
have been constructed using poolcfg itself or libpool(3LIB)
directly.
The configurations which are created by this tool may 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.
-f command_file
Take the commands from command_file. command_file con-
sists of editing commands, one per line.
-h Display extended information about the syntax of edit-
ing 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.
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.
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.
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 formats(5).
float Scientific notation is not supported.
EXAMPLES
Example 1: Creating an Initial Configuration File
The following command creates an initial configuration file
for this host. By not supplying a file name,
/etc/pooladm.conf is assumed.
$ poolcfg -c discover
Example 2: Creating an Initial Configuration File
The following command creates an initial configuration file
for this host and writes it to /home/admin/new_config:
$ poolcfg -c discover /home/admin/new_config
Example 3: 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 4: 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 5: 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 6: Displaying the Current Configuration
The following command displays the current configuration:
$ poolcfg -c 'info' /etc/pooladm.conf
