Exchanging SSH Key with Mates

Use this option to allow two or three servers in a cluster to SSH to each other without entering a password. This simplifies back-end operations that rely on SSH. This step is required in the initial configuration of a cluster, but must be done after the topology is defined in the CMP system.
Note: The SSH keys exchange must be within the cluster (executed from one blade only).

To perform the exchange:

  1. From the Policy Configuration Menu screen, select Exchange SSH Key with Mate and press Enter.

    A screen similar to the following is displayed:

    Exchange SSH Keys for mate node

  2. Enter the Hostname or IP address of the server's mates, select OK and press Enter.

    The SSH key is exchanged between all servers in the cluster:
    • in a two-server cluster, execute the exchange from one server to the other
    • in a three-server Georedundant cluster, execute the exchange from two different servers
    • in a four-server Georedundant cluster, execute the exchange from three different servers

    SSH keys are exchanged between the two servers.
