The Advanced node failure detection function can reduce the number of failure scenarios that result in cluster partitions.
Before you begin
An HMC (minimum V8R8.5.0) is required to implement and configure advanced node failure detection. See Planning advanced node failure detection for hardware and software requirements.
The setup instructions include steps for creating a *SYSTEM certificate keystore. This keystore may have already been created. If so, the password is required. Ask your IBM® i administrator for the keystore and access information.
About this task
To allow a an HMC using REST server to notify IBM i cluster nodes of sudden partition changes or system failures, communication between the HMC and the cluster nodes must be enabled. A digital certificate from the HMC is required and a secure certificate keystore and access to the certificate, if necessary, must be created. This certificate from the HMC is copied and installed on every node in the cluster that requires monitoring.
