Configuring 1-to-N 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 a 1-to-N Remote Copy relationship, a single primary (source) system uses multiple systems as
backup systems. 1-to-N 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. For the current release, a 1-to-N Remote Copy configuration can have a maximum
of two backup systems.
NOTE: In order to configure 1-to-N Remote Copy, you must have at least two available systems
with configured Remote Copy ports.
To configure 1-to-N 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.
