After all components in a Topology Split Manager deployment have been installed and configured, a user starts all components in the deployment and initiates a full discovery. When per-device (phase 2) discovery completes, and assuming that the NumberOfDomains configuration parameter is set, the Topology Split Manager starts a topology split driver that invokes topology split.
In addition, if the Topology Split Manager has already performed a full discovery of the devices in the managed IP network domain (and, again, assuming that the NumberOfDomains configuration parameter is set), the user can enter the following command from the TSM_BASEDIR/smarts/bin directory to invoke topology split:
dmctl -s <TSM name> invoke GA_Driver::TopoSplit-Driver start
where <TSM name> is the name of the Topology Split Manager.
