Establish Communications Between the Quad Appliances

On each of the DR members, issue key-join.
Note: Appliances in the DR cluster exchange SSH Secure Shell keys. Consequently, SSH port 22 and RSYNC port 873 must be open between members of the quad.

Additionally, agent port 9990 is used to exchange status information between cluster members and must be open.

This command establishes communications between the appliances in the DR cluster.

The key is a key-pair automatically generated by the DR leader during initial setup. When you issue key-join, the DR members retrieve and install the DR key. All DR members use the same DR key.
