ONTAP 9.0 and later versions.
When creating a cluster peer relationship, the cluster gets peered in one direction and not the other. Using the following command from cluster 1 works fine:
cluster1::>cluster peer create -peer-addrs 220.127.116.11,18.104.22.168
When running this command from cluster 2, it fails:
cluster2::>cluster peer create -peer-addrs 10.64.23.34,10.64.23.35
Error: command failed: Using peer-address 10.64.23.34: An introductory RPC to the peer address "10.64.23.34" failed to connect: RPC: Remote system error - Operation timed out.Verify that the peer address is correct and try again.
