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 8 JSON Objects for CPG LDLayout

CPG RAIDType Enumeration

Upon creation, modification, and query, the RAID type is specified as an enumeration as shown
in Table 9 (page
