2021: Partner cluster IP address unreachable.

Explanation

Partner cluster IP address unreachable.

User Response

1. Verify the system IP address of the remote system forming the partnership.
2. Check if remote cluster IP address is reachable from local cluster. The following can be done to verify accessibility:
   1. Use svctask to ping the remote cluster IP address. If the ping works, there may be a block on the specific port traffic that needs to be opened in the network. If the ping does not work, there may be no route between the system. Check the IP gateway configuration on the SAN Volume Controller nodes and the IP network configuration.
   2. Check the configuration of the routers and firewall to ensure that TCP/IP port 3620 used for IP partnership is not blocked.
   3. Use the ssh command from another system to attempt to establish a session with the problematic remote cluster IP address to confirm that the remote cluster is operational.
