Use the following commands to verify connectivity for the remote-copy pair you are configuring.
•
For RCIP remote-copy pairs:
# controlport rcip ping <IP_address> <N:S:P>
•
For RCFC remote-copy pairs:
# showrctransport -rcfc
For more information, see “Verifying That the Servers Are Connected” (page 32) .
