5.7.2 Removing the Domain Association from a Domain Object
 To remove the domain association from a domain object, issue the
movetodomain -vv|-cpg|-host <object_name> -unset
command, where:
◆ -vv|-cpg|-host is the type of object (VV, CPG, host, respectively) from which you are
removing the domain association.
◆ <object_name> is the name of the VV, CPG, or host from which you are removing the
domain assocation.
5.8 Managing Virtual Domain Autonomic Groups
Virtual domains can be combined into autonomic groups, which are sets that can be managed
as one object. Virtual domain sets are part of the Autonomic Groups feature. Virtual domains
can be combined into autonomic groups, which are sets that can be managed as one object. If
you have a group of domains that require the same administrative procedures, it is easier to
group those domains into a set and manage them together. For example, you can create a
domain set and put all the hosts in a cluster into a host set. By setting the domain of the hosts
in the host set to the newly created domain set, all the virtual volumes exported to one host in
the cluster are accessible to all the hosts in the cluster. If one of the hosts in the cluster is a
backup host, all of the virtual volumes in the domain set can access the backup host. Without
domain sets there is no way for a host to access volumes from different domains at the same
time. Individual domains can be members of multiple domain sets.
Hosts are the only objects that can be a member of a domain set. All other objects can only
belong to a single domain. If a host that is a member of a domain set is moved with the
movetodomain command to an individual domain, then all objects associated with the host
must be members of the destination domain or the command will fail. Moving a host to a
domain set does not change the domain of any objects associated with the host. If a volume is
exported to a host that is a member of a domain set is selected directly or indirectly by the
movetodomain command, the move does not propagate to the host or any of the volumes
exported to the host if the domain set includes the destination domain of the volume.
Virtual domains added to a set inherit the privileges of that set. Any action that requires
browse privileges for a host requires the user to have browse privileges in any domain in the
domain set. Any action that requires edit privileges for the host requires the user to have edit
privileges in all domains in the domain group.
A virtual domain in a virtual domain set cannot be removed from the system until it has been
removed from the virtual domain set, or until the virtual domain set is removed from the
