IP Manager discovers the Control Station and gets the list of file servers and its details through HTTP adapter, this information is cached in the NASChassis class.
The Control Station objects such as, Host, fileserver, and NASChassis will be created in the IP Manager.
Note:
When the Host (Control Station) is discovered from IP Manager, both the Host (Control Station) and File Server (Data Mover) objects are moved to the pending list, as UNDISCOVERED although the host is present in the topology. When the Data Movers are discovered, all the NAS devices are removed from the pending list.
