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

1. Automatically search and collect MTMS information from the servers
2. Write discovered-bmc-nodes to xCAT (recommended to set different BMC IP address)
3. Create predefined-compute-nodes to xCAT providing additional properties
4. 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.

  • Set static BMC IP using different IP address (recommended)
  • Set static BMC IP using dhcp provided IP address
