NOTE:
When creating additional groups, if you select a server other than the server selected
during the first instance of group creation, you will create a bidirectional Remote Copy
relationship where each storage server will be both the primary and backup servers to the
other. For N-to-1 Remote Copy, you can only create a bidirectional configuration for one
Remote Copy group pair.

Configuring N-to-1 Remote Copy
NOTE:
HP 3PAR Remote Copy Software requires an HP 3PAR Remote Copy license. For additional
information about the license, see the HP 3PAR InForm 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:
In order 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, click Remote Copy.
2.
In the Common Actions panel, click New Configuration.
The New Remote Copy Configuration wizard appears.
