HP 3PAR Web Service API 1.3.1 Developer's Guide

4 Working with Storage Volumes
This chapter describes how to manage storage volumes. The sections apply to creation, modification,
and query operations on storage volumes. You can perform the following operations on storage
volumes:
• Create a storage volume
• Modify a storage volume (since WSAPI 1.2)
• Remove a storage volume (since WSAPI 1.2)
• Query a storage volume (since WSAPI 1.3)
Volume Enumeration and Configuration Objects
Several enumerations and configuration objects are used for the various volume API operations.
These are described in the following sections.
Volume provisioningType Enumeration Types
Enumeration for the provisioningType JSON object is shown in Table 28 (page 52).
Table 28 Volume provisioningType Enumeration
DescriptionValueSymbol
FPVV, either with no snapshot space or with statically allocated snapshot
space.
1FULL
Also, a commonly-provisioned VV where the user space is fully provisioned
and the snapshot space is associated with the snapCPG property.
TPVV, with space for the base volume allocated from the user space that is
associated with the userCPG property.
2TPVV
Also includes old-style thinly provisioned VV (created on a 2.2.4 release
or earlier) where both the base VV and snapshot data are allocated from
the snapshot space associated with userCPG.
The VV is a snapshot (Type vcopy) and its space is provisioned from the
base volume's snapshot space.
3SNP
Remote volume admitted into the local storage system.4PEER
Unknown.5UNKNOWN
Volume CopyType Enumeration Types
Enumeration for the CopyType JSON object is shown in Table 29 (page 52).

Physical copy (full copy).2PHYSICAL_COPY
Snapshot copy (virtual copy).3VIRTUAL_COPY
