4 HP 3PAR Virtual Domains

Overview

When initially setting up the HP 3PAR storage system, the system administrator creates and assigns
users with roles and rights in the system. You can create, modify, and remove a user's access to
HP 3PAR Virtual Domains Software in the system with both the HP 3PAR Command Line Interface
(CLI) and the HP 3PAR Management Console. Refer to the HP 3PAR Command Line Interface
Administrator's Manual and the HP 3PAR Management Console Online Help for instructions on
how to perform these tasks.
NOTE: Virtual domains require an HP 3PAR Virtual Domains Software license. For additional
information about the license, see
In addition to the inherent security provided by this hierarchical user structure, finer grain access
control of the system can optionally be achieved through the implementation of virtual domains.
Domains allow an administrator to create up to 1,024 domains, or spaces, within an system,
where each domain is dedicated to a specific application. A subset of the system users have
varying rights over the domains. The use of domains can be useful in scenarios where a single
system is used to manage data from several different independent applications
Figure 2 Single System Managing Multiple Independent Applications
Each domain allows users with varying levels of accessibility to domain objects. A domain is made
of Common Provisioning Groups (CPGs), hosts, and Remote Copy groups. Domains contain derived
domain objects such as Virtual Volumes (VVs), Logical Disks (LDs), and volume exports (VLUNs).
Because objects are domain-specific, domain users cannot accidentally or deliberately export VVs
to hosts outside of their assigned domain.
Virtual domains can be grouped into autonomic groups that can be managed as one domain. If
you have a group of domains that require the same administrative procedures, it is easier to group
those domains into an autonomic group and mange them together.
NOTE: Remote Copy requires an HP 3PAR Remote Copy Software license. For additional
information about the license, see

Domain Types

When using domains for access control, accessibility to basic objects and derived objects is limited
by a user's role and domain assignment. For more information about roles and rights, see,
