This section contains high-level examples of how you can configure volume creation using ISP.
Using Storage Pool Policies
As described in “Policy” on page 6, a storage pool’s policies affect how it allocates LUNs to create
new volumes, and how it uses templates. By selecting which templates and LUNs are associated
with a storage pool, and setting appropriate policies on the storage pool, you can control how
storage is allocated to volumes. For example, a storage pool might be composed entirely of LUNs
that have a hardware snapshot capability (for example, EMC Business Continuity Volumes).
Setting the AutoGrow policy to pool ensures that the entire storage pool remains
snapshot-capable as illustrated in “Effect of Setting the Value of the AutoGrow Policy to pool.”
Effect of Setting the Value of the AutoGrow Policy to pool
If the AutoGrow policy level were to remain set to the default value of diskgroup, this would
allow the ISP to aggregate LUNs from the disk group.
