17.7 Unconfiguring NNMi from an HA cluster
The process of removing an NNMi node from an HA cluster involves undoing the HA configuration for that instance of NNMi. You can then run that instance of NNMi as a stand-alone management server, or you can uninstall NNMi from that node.
To keep NNMi configured for high availability, the HA cluster must contain one node that is actively running NNMi and at least one passive NNMi cluster node. If you want to completely remove NNMi from the HA cluster, you must unconfigure the HA functionality on all nodes in the cluster.
To completely unconfigure NNMi from an HA cluster, follow the steps described below.
To unconfigure NNMi on the active cluster node, the procedure for deleting the NNMi data is described as well as the procedure for using the NNMi data on the single server after NNMi has been unconfigured from the HA cluster.

For HA Monitor, unconfigure NNMi without using nnmhaunconfigure.ovpl. For details about the procedure, see the Release Notes.
