Licensing NNMi in a High Availability Cluster

NNMi requires two licenses to run NNMi in a High Availability (HA) cluster:

  • One production license locked to the IP address of one of the physical cluster nodes
  • One non-production license locked to the virtual IP address of the NNMi HA resource group

The NNMi license keys are managed on the shared disk. Therefore, each NNMi HA resource group requires only the non-production license keys for each separately licensed product.

When licensing NNMi in an HA cluster, you must update the licenses.txt file on the shared disk with the new information from the license file on the active node. Complete the following procedure to correctly license NNMi in an HA cluster.

  • If you have purchased NNMi Premium or NNMi Ultimate, instead of using a non-production license as directed, you need to use the license key or license keys you requested from the Password Delivery Center for use with High Availability. Obtain a license key for the virtual IP address of the NNMi HA resource group. This license key is initially used on the primary server and then used on the secondary server when needed.

Caution Do not use production and non-production licenses on the same server.

To correctly license NNMi in an HA cluster, perform these steps on the active NNMi cluster node:

  1. Obtain and install a permanent license key for each of your ordered products as described in Apply Licenses. When prompted for the IP address of the NNMi management server, provide the virtual IP address of the NNMi HA resource group.

  2. Update the licenses.txt file on the shared disk with the new information from the LicFile.txt file on the active node. Do one of the following:

    • If the licenses.txt file exists in the NNM directory on the shared disk, append the new license keys in LicFile.txt on the active node to licenses.txt on the shared disk.
    • If the licenses.txt file does not exist on the shared disk, copy LicFile.txt from the active node to licenses.txt in the NNM directory on the shared disk.

    On the active node, the LicFile.txt file is in the following location:

    • Windows: %NnmDataDir%\shared\nnm\conf\licensing\LicFile.txt
    • Linux: $NnmiDataDir/shared/nnm/conf/licensing/LicFile.txt

    On the shared disk, example locations of the licenses.txt file are as follows:

    • Windows: S:\NNM\licenses.txt
    • Linux: /nnmount/NNM/licenses.txt
