Grouping To Simplify Volume Operations; Copy Groups - HP XP P9500 Software User's Manual

Grouping to simplify volume operations

Business Continuity Manager can group together copy pairs to improve the operability of managing
replicas of large-scale systems that handle substantial amounts of data. Copy pairs can be grouped
together and managed as a single entity. These group types are:
Copy groups (see
Consistency groups (see
Copy group containers (see
CAUTION:
operated on as a consistency group. The consistency group can then only be operated on by
performing operations on the copy group container.
Working with copy pairs in groups simplifies volume operation and reduces system administration
costs.

Copy groups

A copy group is a set of copy pairs that have the same copy type (Business Copy for Mainframe,
Continuous Access Synchronous for Mainframe, Continuous Access Asynchronous for Mainframe
or Continuous Access Journal for Mainframe), and is designated a copy group id for identification.
An operation performed on a copy group is performed on all of the copy pairs within that copy
group.
To define a copy group and assign a copy group id, see
