Configuring Ports for RCIP
For 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 eight links between systems. Up to eight nodes can each have
one GigE port contributing links to an RCIP remote-copy pair.
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 StoreServ
Storage 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 HP 3PAR Remote Copy software.
Setting Up the Remote-Copy Interface for RCIP
Perform the following steps to set up a remote-copy interface for RCIP. Use the setup information
you gathered in the
“RCIP Initial Remote-Copy Pair Worksheet” (page 27) . If you are configuring
multiple systems, use the setup information you gathered in both the “RCIP Initial Remote-Copy Pair
Worksheet” (page 27) and the “RCIP Additional Remote-Copy Pairs Worksheet” (page 28) .
1. If the IP addresses for RCIP already exist and you are reconfiguring the remote-copy interface,
use the following commands:
a.
Remove the existing links by issuing the following command:
# dismissrcopylink ...
where:
•
—Name of the target (System2)
•
—Location of a primary system Ethernet port, expressed as node:slot:port
(System1)
•
—IP address of the peer port on the target system (System2)
b. Add the new links by issuing the following command:
# admitrcopylink ...
2. Issue the following command for an Ethernet port on one remote-copy system:
# controlport rcip addr
where:
•
—IP address assigned to the Ethernet port
•
—Netmask to be assigned
•
—Location of a primary system Ethernet port, expressed as node:slot:port
3. Enter y to confirm you want to make the gateway change.
