Configuring N-to-1 Remote Copy
NOTE: HP 3PAR Remote Copy Software requires an HP 3PAR Remote Copy license. For more
information about the license, see the HP 3PAR OS Concepts Guide.
In an N-to-1 Remote Copy relationship, a maximum of four primary (source) systems use the same
system as backup system. N-to-1 Remote Copy configurations can operate in either a combination
of unidirectional and bidirectional (for a single Remote Copy group pair), or in complete
unidirectional functionality.
NOTE: To configure N-to-1 Remote Copy, you must have at least two available systems with
configured Remote Copy ports.
To configure N-to-1 Remote Copy:
1. In the Manager Pane, select Remote Copy.
2. In the Common Actions panel, click New Configuration. The New Remote Copy Configuration
wizard appears.
