Updating Cluster Key
The steps to generate a new set of the cluster SSH keys.
Before you begin
Ensure that all the nodes in the cluster are active, before changing the cluster key.
If a new key is deployed to a node that is unreachable, then connect the node to the cluster. In this scenario, remove the node from the cluster and re-join the cluster.
Generate a new set of the cluster SSH keys to the nodes that are directly connected to the local node. This ensures that the trusted appliance cluster is secure.
To re-generate cluster keys:
In the ESA CLI Manager, navigate to Tools > Clustering > Trusted Appliances Cluster > Maintenance: Update Cluster Settings.
The following screen appears.
Select New Cluster Keys.
A message to re-generate the cluster keys appears.
Select Yes.
The new keys are deployed to the nodes that are directly connected.
