19.4.1 Configuring NNMi certificates for HA
The NNMi installation process configures a self-signed certificate for secure communications between the NNMi console and the NNMi database. The process for configuring NNMi for HA correctly shares the self-signed certificate among the primary and secondary cluster nodes. You do not need to take any extra steps to use the default certificate with NNMi running under HA.
If you want to use a different self-signed certificate or a Certificate Authority (CA)-signed certificate for NNMi communications, you must do some additional work. After obtaining the new certificate, complete the steps shown in 10.3.6 Working with Certificates in High-Availability Environments. You can complete this procedure before or after configuring NNMi for HA.
