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: • Query storage volume • Create a storage volume • Modify a storage volume (since WSAPI 1.2) • Remove a storage volume 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 25 (page 38). Table 25 Volume provisioningType Enumeration Symbol FULL Value 1 Description Fully provisioned VV, either with no snapshot space or with statically allocated snapshot space. Also, a commonly-provisioned VV where the user space is fully provisioned and the snapshot space is associated with the snapCPG property. TPVV 2 Thinly-provisioned virtual volume, with space for the base volume allocated from the user space that is associated with the userCPG property. Also includes old-style thin 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. SNP PEER UNKNOWN 3 The VV is a snapshot (Type vcopy) and its space is provisioned from the base volume's snapshot space. 4 Remote volume admitted into the local storage system. 5 Unknown.
