Synchronous Mode
Backup system 2 (SystemC) is located far from the primary system and backup system 1, and
therefore must use an IP network.
•
An IP network connects all systems. (The two backup systems use the IP network to share a
standby link for failover and recovery purposes.)
•
Replication between SystemA and SystemC is in asynchronous periodic mode.

Verifying Connectivity between Systems
Verify the connectivity for each Remote Copy pair you are configuring.
•
RCIP Remote Copy pairs:
# controlport rcip ping <IP_address> <N:S:P>
•
RCFC Remote Copy pairs:
# showrctransport -rcfc
For more information, see “Verifying the Servers Are Connected” (page 35) .
