6 Setting the Transport Layer
Follow the steps for your chosen transport layer.

Setting Up Remote Copy over IP
Configuring Ports for RCIP
For Remote Copy over IP (RCIP) configurations, each link between a Remote Copy pair is a logical
link between a controller node on one storage system and a controller node on the other storage
system in the pair. These links use a GigE port from each of the nodes in the storage systems that
belong to the Remote Copy pair.
RCIP configurations can use up to four links between systems; in other words, up to four nodes can
have one GigE port each contributing links to an RCIP configuration.
• If these ports were not set up during the initial setup of the storage system, or if the configuration
has changed, reconfigure the ports before you set up the Remote Copy transport layer.
To configure the ports, use the CLI command controlport rcip.
CAUTION: The GigE interface and the management Ethernet port of an HP 3PAR Storage System
controller node must be on different IP subnets.
If the interface and port are configured on the same subnet, Remote Copy packets might go over
the management port, and would therefore not be available to the Remote Copy software.
Setting Up the Remote Copy Interface for RCIP
Use the setup information you gathered in the “RCIP Initial Remote Copy Pair Worksheet” (page 30).
If you are configuring multiple systems, use the setup information you gathered in both the “RCIP
Initial Remote Copy Pair Worksheet” (page 30) and the “RCIP Additional Remote Copy Pairs
Worksheet” (page 31).
1. If the IP addresses for RCIP already exist and you are reconfiguring the Remote Copy interface:
a. Remove the existing links:
# dismissrcopylink <target_name> <N:S:P:IP_address>...
• <target_name> - The name of the target (for example, System2)
• <N:S:P> - Node, slot, and port of the Ethernet port on the primary system (for
example, on System1)
• <IP_address> - IP address on the target system (for example, on System2)
b. Add the new links:
# admitrcopylink <target_name> <N:S:P:IP_address>...
