MTMS-based Discovery
MTMS stands for Machine Type/Model and Serial. This is one way to uniquely identify each physical server.
MTMS-based hardware discovery assumes the administrator has the model type and serial number information for the physical servers and a plan for mapping the servers to intended hostname/IP addresses.
Overview
Automatically search and collect MTMS information from the servers
Write discovered-bmc-nodes to xCAT (recommended to set different BMC IP address)
Create predefined-compute-nodes to xCAT providing additional properties
Power on the nodes which triggers xCAT hardware discovery engine
Pros
Limited effort to get servers defined using xCAT hardware discovery engine
Cons
When compared to switch-based discovery, the administrator needs to create the predefined-compute-nodes for each of the discovered-bmc-nodes. This could become difficult for a large number of servers.
