System Administration Commands pooladm(1M)
NAME
pooladm - activate and deactivate the resource pools facil-
ity
SYNOPSIS
/usr/sbin/pooladm [-n] [-s] [-c] [filename] | -x
/usr/sbin/pooladm [-d | -e]
DESCRIPTION
The pooladm command provides administrative operations on
pools and sets. pooladm reads the specified filename and
attempts to activate the pool configuration contained in it.
Before updating the current pool run-time configuration,
pooladm validates the configuration for correctness.
Without options, pooladm prints out the current running
pools configuration.
OPTIONS
The following options are supported:
-c Instantiate the configuration at the given
location. If a filename is not specified, it
defaults to /etc/pooladm.conf.
-d Disable the pools facility so that pools can
no longer be manipulated.
-e Enable the pools facility so that pools can
be manipulated.
-n Validate the configuration without actually
updating the current active configuration.
Checks that there are no syntactic errors
and that the configuration can be instan-
tiated on the current system. No validation
of application specific properties is per-
formed.
-s Update the specified location with the
details of the current dynamic configura-
tion.

System Administration Commands pooladm(1M)
This option requires update permission for
the configuration that you are going to
update. If you use this option with the -c
option, the dynamic configuration is updated
before the static location.
-x Remove the currently active pool configura-
tion. Destroy all defined resources, and
return all formerly partitioned components
to their default resources.
OPERANDS
The following operands are supported:
filename Use the configuration contained within this
file.
EXAMPLES
Example 1: Instantiating a Configuration
The following command instantiates the configuration con-
tained at /home/admin/newconfig:
example# /usr/sbin/pooladm -c /home/admin/newconfig
Example 2: Validating the Configuration Without Instantiat-
ing It
The following command attempts to instantiate the configura-
tion contained at /home/admin/newconfig. It displays any
error conditions that it encounters, but does not actually
modify the active configuration.
example# /usr/sbin/pooladm -n -c /home/admin/newconfig
Example 3: Removing the Current Configuration
The following command removes the current pool configura-
tion:
example# /usr/sbin/pooladm -x
Example 4: Enabling the Pools Facility
The following command enables the pool facility:

System Administration Commands pooladm(1M)
example# /usr/sbin/pooladm -e
Example 5: Enabling the Pools Facility Using SMF
The following command enables the pool facility through use
of the Service Management Facility. See smf(5).
example# /usr/sbin/svcadm enable svc:/system/pools:default
Example 6: Saving the Active Configuration to a Specified
Location
The following command saves the active configuration to
/tmp/state.backup:
example# /usr/sbin/pooladm -s /tmp/state.backup
FILES
/etc/pooladm.conf Configuration file for pooladm.

Management, and Solaris Zones
NOTES
Resource bindings that are not presented in the form of a
binding to a partitionable resource, such as the scheduling
class, are not necessarily modified in a pooladm -x opera-
tion.
The pools facility is not active by default when Solaris
starts. pooladm -e explicitly activates the pools facility.

System Administration Commands pooladm(1M)
The behavior of certain APIs related to processor partition-
ing and process binding are modified when pools is active.
See libpool(3LIB).
You cannot enable the pools facility on a system where pro-
cessor sets have been created. Use the psrset(1M) command or
pset_destroy(2) to destroy processor sets manually before
you enable the pools facility.
Because the Resource Pools facility is an smf(5) service, it
can also be enabled and disabled using the standard SMF
interfaces.
