8.3.3 Promoting a Physical Copy
Over time, physical copies and their base volumes can change as data is written to each. At
some point the association between the two volumes may no longer be relevant. The
association between a physical copy and a base volume is broken by promoting the physical
copy back to the base volume.
 To promote a physical copy to back to a base volume, issue the
promotevvcopy <copy_name> | set:<set_name> command, where:
◆ <copy_name> is the name of the physical copy being promoted.
◆ <set_name> is the name of the physical copy set being promoted.
8.4 Snapshots and Domains
As with standard systems, virtual copies and physical copies can also be created in systems
using 3PAR Virtual Domains. Domain snapshot creation and modification does not differ from
snapshot creation and modification in systems not using Domains. Domain snapshot creation
and modification is limited to super and edit level users belonging to the
all domain and edit
level users belonging to a
specified domain. Snapshots inherit the domain of their parent
volumes.
