HP Storage Provisioning Manager (SPM) version 2.3 User Guide

Understanding HP 3PAR StoreServ Storage System virtual domains
HP 3PAR Virtual Domain software provides a user-based, restricted access system for managing
storage resources. Using virtual domains, a user can be given private control of their storage
resources, without the ability to see any other users' resources. Storage resources can be managed
and provisioned as necessary.
SPM represents HP 3PAR virtual domains in the form of separate "domain arrays”, one for each
domain defined on the storage system. HP 3PAR virtual domains are displayed as separate array
entries in the format Array name (virtual domain name).Components that do not belong to any
domain are included in a domain array called the “–“ domain array or default array. Once
imported into the SPM catalog, HP 3PAR domain arrays and the components they contain can be
used like normal arrays and components.
Firmware version support for virtual domains
SPM does not support virtual domains on versions of firmware earlier than 3.1.1 MU1. For firmware
later versions of firmware, virtual domains are supported without limitations. For supported firmware
versions, see “Minimum requirements” (page 12).
For firmware version 3.1.1 MU1, virtual domains are supported with the following restrictions:
• Empty domains are not visible.
• You cannot create a host in a given domain.
• You cannot determine what domains a domain set is made up of.
Licensing
To enable SPM to see virtual domains on an HP 3PAR StoreServ Storage System, a Domains license
must be installed on the storage system.
Capabilities
The capabilities of an array are computed based on the ability of a user to see virtual domains on
the storage system, and on the access rights granted to the user for each domain. Users with access
to all virtual domains and super privilege are granted all available capabilities. Other users,
including Edit users, are granted only the Management Signatures capability.
User capabilities are summarized in the following table.

Pools
