5.4 Object and Domain Association Rules
Domains contain basic objects such as CPGs, hosts, and Remote Copy groups, and derived
objects such as VVs, LDs, and VLUNs. Objects and their associations with domains must adhere
to the following rules:
■ Objects derived from a CPG inherit the domain of that CPG.
■ VVs can only be exported to hosts belonging to the VVs’ domain.
■ A VLUN inherits the domain of the VV and host from which the VLUN was exported.
5.5 The Default and Current Domains
When a user is initially created, the user is able access objects in all assigned domains. The user
can browse or edit objects depending on the user’s assigned user class. For example, an edit
level user assigned to Domains A and B can view and work on objects in both Domains A and B
(Figure 5-2). However, if it is apparent that a specific domain will receive the majority of
attention from a user, 3PAR Virtual Domains provides the ability for administrators to set a
default domain for that user.
Figure 5-2. Assigned Domains
An InForm CLI user’s default domain is the domain the user accesses at the start of each CLI
session. For example, if you have edit privileges to Domains A and B and your default domain
has been set to Domain A, each time you start a new CLI session you will view and work with
only objects in Domain A (Figure 5-2). The user’s default domain can be set and reset at any
time by the administrator.
