3.4 Setting the Remote Copy Transport Layer

Prior to setting up Remote Copy, you must set up the Remote Copy transport layer as described

in this section. The method for setting the RC transport layer differs depending on whether the

configuration uses Remote Copy over IP (RCIP) or Remote Copy over Fibre Channel (RCFC).

However, note that this is the only part of the Remote Copy setup that differs between RCIP or

RCFC.

3.4.1 Setting Up Remote Copy Over IP

For RCIP configurations, each link between a Remote Copy pair is a physical link between a

controller node on one storage server and a controller node on the other storage server in the

pair. These physical links use a GigE port from each of the two nodes in the storage servers that

belong to the Remote Copy pair. Typically, these ports are configured during the initial setup

of the storage system.

If setup did not occur, or the configuration has changed, you will need to reconfigure the ports

before you can begin setting up Remote Copy. Ports are configured using the

controlport rcip

command. See

Appendix B, Remote Copy Commands

for more

information on this command. See the InForm OS Command Line Interface Reference for

complete information on using this command.

CAUTION: When configuring the GigE interfaces, the GigE interface and the

management Ethernet port of an InServ Storage Server controller node should be

on different IP subnets. If they are configured on the same subnet, Remote Copy

packets might go over the management port and would not be available to the

Remote Copy software.
