Setting Up Dedicated Node Pairs for RCFC
• Verify that each Fibre Channel interface on each node on the primary Remote Copy system
connects to a dedicated Fibre Channel interface on each node on the backup Remote Copy
system.
RCFC requires a dedicated node pair per target. For example:
Figure 16 Remote Copy over Fibre Channel Dedicated Node Pairs
In Figure 16 (page 39):
• Fibre Channel interfaces on nodes 0 and 1 on the Primary System connect to Fibre Channel
interfaces on Backup System1 nodes 0 and 1, respectively.
• Fibre Channel interfaces on nodes 2 and 3 on the Primary System connect to Fibre Channel
interfaces on Backup System2 nodes 0 and 1, respectively.
Setting Up the Remote Copy Interface for RCFC
Use the setup information you gathered in the “RCFC Remote Copy Pair Worksheet” (page 32):
1. Enter the following command for a Fibre Channel adaptor port on one storage system:
# controlport config rcfc -ct point -f <N:S:P>
• -ct point - point-to-point mode
• <N:S:P> - Fibre Channel adaptor port to configure, expressed as node:slot:port
2. To obtain the RCFC port positions, issue the showport -rcfc command:
# showport -rcfc
3. Record the port positions in the “RCFC Remote Copy Pair Worksheet” (page 32) worksheet.
4. Repeat Step 1 through Step 3 for each port on each system in the Remote Copy configuration.
5. To verify that the Fibre Channel communication links have been established, issue the
showrctransport -rcfc command.
# showrctransport -rcfc
The Fibre Channel adaptor ports should appear, and the State column should display new.
