Cluster: Cluster Configuration

Unlock / Lock the Cluster Configuration

Clustering different versions of the Next Generation Hardware Appliance is not supported!

To make changes to the cluster configuration - for example, adding or deleting a node - you must first unlock the cluster configuration form. This is a security feature to prevent accidental changes to the cluster or simultaneous changes by different users. Proceed as follows:

1. Log in to your Keyfactor Next Generation Hardware Appliance.

2. Open the Cluster page.

3. In the section Cluster Members, click Unlock to make changes.

4. You are notified that you have 5 minutes to make your changes.
   If you need more time, click Extend Lease to get another 5 minutes.

5. Information about locks is shared among all cluster nodes.

6. When you retrieve a lease on Node1, all other nodes are notified that Node1 is holding the lease.

7. A user on another node can click Acquire Lease to request the lease from you / Node1.
   When you grant this, the lease will be held exclusively by that other node. It can only be requested again after it expires.

It may happen that the window for the cluster configuration does not open after clicking Unlock to make changes and no time window or less than 5 minutes is provided.

Before setting up the cluster, ensure that the time on the nodes is synchronized.

NTP Time Synchronization
is used to establish a connection to the NTP Server(s) and
synchronize the time of the appliance time with them.

Please refer to NTP Server Configuration.
