38 Understanding ISP
About ISP concepts
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.
■ For storage pools that are created explicitly by using the vxpool command,
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.
■ For storage pools that are created implicitly by specifying the -o intent
option to the
vxassist make command when creating a volume, the default
level of the SelfSufficient policy is host. This allows any template that
has been installed in the ISP configuration database to be used.
Figure 1-12 illustrates the scope of the levels that can be configured as policy
values for a storage pool.
