HP 3PAR Web Service API 1.3.1 Developer's Guide

3 Working with Common Provisioning Groups
You can use a common provisioning group (CPG) to create a virtual pool of logical disks that
allows virtual volumes to share the resources of the CPG and allocates space on demand. You can
create fully-provisioned virtual volumes (FPVVs) and thinly-provisioned virtual volumes (TPVVs) that
draw space from the logical disk pool.
You can use this chapter to:
• Create a CPG
• Modify a CPG
• Remove a CPG
• Query a CPG
CPG Enumeration and Configuration Objects
Many of the CPG operation objects have enumerations or contain sub-objects, as described in the
following sections.
CPG LDLayout JSON Objects
LDLayout is a sub-object of the CPG object for creation and modification. It is also returned within
the CPG’s SAGrowth and SDGrowth objects upon query of CPGs. See Table 10 (page 42).

CPG RAIDType Enumeration
Upon creation, modification, and query, the RAID type is specified as an enumeration as shown
in Table 11 (page 42).
