pool Use templates that have been manually assigned to
the storage pool.

The values of these two policies can be combined to suit how the storage pool is to be used.
The policy levels that are associated with a storage pool control how it manages its templates and
LUNs:
◆ The default level of the AutoGrow policy is diskgroup. This allows LUNs that are
associated with the storage pool and its disk group to be used for allocating storage to volumes.
◆ The default level of the SelfSufficient policy is pool. This allows only templates that
are associated with the storage pool to be used for allocating storage to volumes. The storage
pool can contain only volumes with the reliability and performance capabilities that are
supported by these templates.
The scope of the levels that can be configured as policy values for a storage pool is illustrated in
“Scope Levels for Storage Pool Policies.”
