HP 3PAR StoreServ Concepts Guide: HP 3PAR OS 3.1.3

4 HP 3PAR Virtual Domains
Overview
To set up the HP 3PAR storage system, the system administrator creates and assigns user 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 CLI and the HP 3PAR Management Console.
See the HP 3PAR Command Line Interface Administrator’s Manual and the HP 3PAR Management
Console Online Help for instructions on performing these tasks.
NOTE: Virtual domains require an HP 3PAR Virtual Domains Software license. For additional
information about the license, see “HP 3PAR Software” (page 10).
In addition to the security provided by this hierarchical user structure, more defined control of
access to the system can be achieved by implementing virtual domains.
Domains allow an administrator to create up to 1,024 domains, or spaces, within a 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. See Figure 3 (page 25).
Figure 3 Single System Managing Multiple Independent Applications
Each domain allows users varying levels of accessibility to domain objects. A domain contains
CPGs, hosts, and remote-copy groups, and derived domain objects, such as virtual volumes, LDs,
and volume exports (VLUNs). Because objects are domain-specific, domain users cannot export
virtual volumes 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 “HP 3PAR Software” (page 10).
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, “HP
3PAR Storage System Users” (page 19).
