19.1.2 NNMi HA cluster scenarios

For NNMi HA configuration, NNMi is installed on each system that will become part of an HA resource group. The NNMi database is installed on a separate disk that is accessed by the NNMi programs running on each system. (Only one system, the active cluster node, accesses the shared disk at any given time.)

Note

Run the NNMi database backup and restore scripts on the active cluster node only.

NNMi-only scenario

The figure below shows a graphical representation of the NNMi HA cluster scenario.

Node A and node B are each a fully installed NNMi management server that contains the NNMi program that runs on that system. The active cluster node accesses the shared disk for runtime data. Other products connect to NNMi by way of the virtual IP address of the HA resource group.
