In general, you can use the dmctl put command to change the value of any basic-type attribute (string, boolean, integer, float, and so on) of any VMware Smart Assurance object. Upon issuing a dmctl command, you might be prompted for a username and password. Respond with your user account. For example, to specify the default administrative account, enter username admin and password changeme.
For IP Manager, you use the dmctl put command to override parameter settings in the discovery.conf file or the name-resolver.conf file. These parameters are defined as attributes of the ICF-TopologyManager object, which is an instance of the ICF_TopologyManager class.
The syntax for the dmctl put command is:
dmctl -s <IP Manager instance name> put ICF_TopologyManager::ICF-TopologyManager::<configuration property> <value>
dmctl -s INCHARGE-AM put ICF_TopologyManager::ICF-TopologyManager::numberProbeThreads 12
