How to Enable the Dynamic Resource Pools Service Using `svcadm`

Become root or assume an equivalent role.

Enable the dynamic resource pools service.

# svcadm enable system/pools/dynamic:default

Example 4 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       2011     svc:/system/pools:default
disabled       2011     svc:/system/pools/dynamic:default

Enable dynamic resource pools:

# svcadm enable svc:/system/pools/dynamic:default
# svcs -a | grep pool
STATE          STIME    FMRI
disabled       2011     svc:/system/pools:default
offline        2011     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 Sat Feb 12 02:36:15 2011
Reason: Disabled by an administrator.
   See: http://support.oracle.com/msg/SMF-8000-05
   See: libpool(3LIB)
   See: pooladm(1M)
   See: poolbind(1M)
   See: poolcfg(1M)
   See: poolstat(1M)
Impact: This service is not running.

svc:/system/pools/dynamic:default (dynamic resource pools)
 State: disabled since Sat Feb 12 02:36:16 2011
Reason: Disabled by an administrator.
   See: http://support.oracle.com/msg/SMF-8000-05
   See: poold(1M)
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         2011     svc:/system/pools/dynamic:default
online         2011     svc:/system/pools:default

Example 5 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       2011     svc:/system/pools:default
online         2011     svc:/system/pools/dynamic:default

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

# svcs "*pool*"
STATE          STIME    FMRI
disabled       2011     svc:/system/pools:default
offline        2011     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 Sat Feb 12 02:36:15 2011
Reason: Disabled by an administrator.
   See: http://support.oracle.com/msg/SMF-8000-05
   See: libpool(3LIB)
   See: pooladm(1M)
   See: poolbind(1M)
   See: poolcfg(1M)
   See: poolstat(1M)
Impact: 1 dependent service is not running.  (Use -v for list.)

svc:/system/pools/dynamic:default (dynamic resource pools)
 State: offline since Sat Feb 12 02:36:15 2011
Reason: Service svc:/system/pools:default is disabled.
   See: http://support.oracle.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         2011     svc:/system/pools:default
online         2011     svc:/system/pools/dynamic:default
