NAME

pooladm - 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
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 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 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 configuration. 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 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
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 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
Service Management Facility. See smf(7).


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
necessarily 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(8) command or pset_destroy(2) to
destroy processor sets manually before you enable the pools facility.


Because the Resource Pools facility is an smf(7) service, it can also
be enabled and disabled using the standard SMF interfaces.
