Use these properties to configure security for the PowerHA® SystemMirror cluster
communication. The default values can be changed to suit your specific
cluster environment.
You can choose one of the following security levels for the cluster:
- Low: Provides heartbeat authentication. This value is the default
setting.
- Medium: Provides encryption of some messages, such as cluster
event communication, as well as heartbeat authentication.
- High: Provides encryption of all messages, including Kernel interfaces,
as well as the heartbeat authentication.
- None: Provides no encryption or hashing for any cluster communication
packets. You cannot configure any other security properties when you
select this security level.
Configuration-related key pairs (certificate and key) are used
to communicate information in a secured manner. By default, a key
pair is created internally, but you can choose to use SSHD-related
key pairs or your own custom key information.
