pooladm(1M) System Administration Commands pooladm(1M)NAMEpooladm - activate and deactivate the resource pools facility
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 vali‐
dates the configuration for correctness.
Without options, pooladm prints out the current running pools configu‐
ration.
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 manipu‐
lated.
-n Validate the configuration without actually updating
the current active configuration. Checks that there are
no syntactic errors and that the configuration can be
instantiated on the current system. No validation of
application specific properties is performed.
-s Update the specified location with the details of the
current dynamic configuration.
This option requires update permission for the configu‐
ration 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 configuration. Destroy
all defined resources, and return all formerly parti‐
tioned 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 contained at
/home/admin/newconfig:
example# /usr/sbin/pooladm -c /home/admin/newconfig
Example 2: Validating the Configuration Without Instantiating It
The following command attempts to instantiate the configuration con‐
tained 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 configuration:
example# /usr/sbin/pooladm -x
Example 4: Enabling the Pools Facility
The following command enables the pool facility:
example# /usr/sbin/pooladm -e
Example 5: Enabling the Pools Facility Using SMF
The following command enables the pool facility through use of the Ser‐
vice 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.

NOTES
Resource bindings that are not presented in the form of a binding to a
partitionable resource, such as the scheduling class, are not necessar‐
ily modified in a pooladm-x operation.
The pools facility is not active by default when Solaris starts.
pooladm-e explicitly activates the pools facility. The behavior of
certain APIs related to processor partitioning and process binding are
modified when pools is active. See libpool(3LIB).
You cannot enable the pools facility on a system where processor 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.
