ProcedureSolaris 10 11/06 and Later: How to Enable the Dynamic Resource Pools Service Using svcadm

  1. Become superuser, or assume a role that includes the Service Management rights profile.

    Roles contain authorizations and privileged commands. For information on how to create the role and assign the role to a user, see Configuring RBAC (Task Map) in System Administration Guide: Security ServicesManaging RBAC (Task Map) in System Administration Guide: Security Services.

  2. Enable the dynamic resource pools service.


    # svcadm enable system/pools/dynamic:default
Example 13–1 Dependency of the Dynamic Resource Pools Service on the Resource Pools Service

This example shows that you must first enable resource pools if you want to run DRP.

There is a dependency between resource pools and dynamic resource pools. DRP is now a dependent service of resource pools. DRP can be independently enabled and disabled apart from resource pools.

The following display shows that both resource pools and dynamic resource pools are currently disabled:


# svcs *pool*
STATE          STIME    FMRI
disabled       10:32:26 svc:/system/pools/dynamic:default
disabled       10:32:26 svc:/system/pools:default

Enable dynamic resource pools :


# svcadm enable svc:/system/pools/dynamic:default
# svcs -a | grep pool
disabled       10:39:00 svc:/system/pools:default
offline        10:39:12 svc:/system/pools/dynamic:default

Note that the DRP service is still offline.

Use the -x option of the svcs command to determine why the DRP service is offline:


# svcs -x *pool*
svc:/system/pools:default (resource pools framework)
 State: disabled since Wed 25 Jan 2006 10:39:00 AM GMT
Reason: Disabled by an administrator.
   See: http://sun.com/msg/SMF-8000-05
   See: libpool(3LIB)
   See: pooladm(1M)
   See: poolbind(1M)
   See: poolcfg(1M)
   See: poolstat(1M)
   See: /var/svc/log/system-pools:default.log
Impact: 1 dependent service is not running.  (Use -v for list.)

svc:/system/pools/dynamic:default (dynamic resource pools)
 State: offline since Wed 25 Jan 2006 10:39:12 AM GMT
Reason: Service svc:/system/pools:default is disabled.
   See: http://sun.com/msg/SMF-8000-GE
   See: poold(1M)
   See: /var/svc/log/system-pools-dynamic:default.log
Impact: This service is not running.

Enable the resource pools service so that the DRP service can run:


# svcadm enable svc:/system/pools:default

When the svcs *pool* command is used, the system displays:


# svcs *pool*
STATE          STIME    FMRI
online         10:40:27 svc:/system/pools:default
online         10:40:27 svc:/system/pools/dynamic:default
Example 13–2 Effect on Dynamic Resource Pools When the Resource Pools Service Is Disabled

If both services are online and you disable the resource pools service:


# svcadm disable svc:/system/pools:default

When the svcs *pool* command is used, the system displays:


# svcs *pool*
STATE          STIME    FMRI
disabled       10:41:05 svc:/system/pools:default
online         10:40:27 svc:/system/pools/dynamic:default
# svcs *pool*
STATE          STIME    FMRI
disabled       10:41:05 svc:/system/pools:default
online         10:40:27 svc:/system/pools/dynamic:default

But eventually, the DRP service moves to offline because the resource pools service has been disabled:


# svcs *pool*
STATE          STIME    FMRI
disabled       10:41:05 svc:/system/pools:default
offline        10:41:12 svc:/system/pools/dynamic:default

Determine why the DRP service is offline:


# svcs -x *pool*
svc:/system/pools:default (resource pools framework)
 State: disabled since Wed 25 Jan 2006 10:41:05 AM GMT
Reason: Disabled by an administrator.

   See: libpool(3LIB)
   See: pooladm(1M)
   See: poolbind(1M)
   See: poolcfg(1M)
   See: poolstat(1M)
   See: /var/svc/log/system-pools:default.log
Impact: 1 dependent service is not running.  (Use -v for list.)

svc:/system/pools/dynamic:default (dynamic resource pools)
 State: offline since Wed 25 Jan 2006 10:41:12 AM GMT
Reason: Service svc:/system/pools:default is disabled.
   See: http://sun.com/msg/SMF-8000-GE
   See: poold(1M)
   See: /var/svc/log/system-pools-dynamic:default.log
Impact: This service is not running.

Resource pools must be started for DRP to work. For example, resource pools could be started by using the pooladm command with the -e option:


# pooladm -e

Then the svcs *pool* command displays:


# svcs *pool*
STATE          STIME    FMRI
online         10:42:23 svc:/system/pools:default
online         10:42:24 svc:/system/pools/dynamic:default
