15.3.3 Considering licensing
You must purchase and install NNMi Advanced licenses on the NNMi management server you plan to use as the global manager. NNMi management servers do not need NNMi Advanced licenses to function as regional managers.
You can use the global network management feature to limit the new licenses you need on the global manager. For example, if your information technology group needs to monitor critical equipment located at multiple sites, you can configure a forwarding filter on the regional managers to make sure you only forward information about critical devices to the global manager. This enables you to make wise use of your NNMi investment and maintain control over your use of the license capacity you have on the global manager.
If you have increased the NNMi licenses for the regional managers such that the total number of licensed nodes is larger than the NNMi Advanced licenses on the global manager, the global manager will not have been able to maintain a complete inventory of all nodes in all regions. To synchronize the global manager with all of the regional managers so that the global manager can find and create the nodes it skipped due to insufficient licenses, you must purchase and install enough NNMi Advanced licenses on the global manager to meet or exceed the total number of licenses you have installed on the regional managers.
After you have enough licenses installed, do one of the following:
Wait for all the configured rediscovery intervals on all the regional managers to elapse so that all nodes in all regions become rediscovered. Once the regional managers have rediscovered all nodes in all regions, they send this rediscovered node information to the global manager.
The global manager receives this node information and creates global nodes for all nodes in each region.
Run the nnmnoderediscover.ovpl -all script on each regional manager.
- Note
The second option results in both a lot of traffic on your network and consumption of a lot of NNMi resources from the entire set of NNMi managers. This option is not as resource intensive as the initial NNMi discovery, but it is similar to doing an initial discovery. The best approach is to space the running of the script for each region by some amount of time or by waiting for the current regional manager's workload to drop to normal before starting the next regional manager's rediscovery.
