Cluster: Cluster Configuration
Unlock / Lock the Cluster Configuration
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:
Log in to your Keyfactor Next Generation Hardware Appliance.
Open the Cluster page.
In the section Cluster Members, click Unlock to make changes.
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.Information about locks is shared among all cluster nodes.
When you retrieve a lease on Node1, all other nodes are notified that Node1 is holding the lease.
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.
