Network Topology: Hybrid setup

For an environment containing both LOM and BMC ports, the provision tool needs to be run twice to correctly manage all servers in the network.

The first time the provision tool is run (to discover the dedicated BMC ports), ensure that the following variables are set in input/provision_config.yml:

  • network_interface_type: dedicated

  • discovery_mechanism: mapping

  • Leave the variables bmc_nic_subnet, bmc_static_start_range and bmc_static_end_range blank in input/provision_config.yml. Entering these variables will cause IP reassignment and can interfere with the availability of ports on your target servers.

  • Do not use the switch_based methods to discover nodes in a Hybrid setup.

Once all the dedicated NICs are discovered, re-run the provisioning tool (to discover the shared LOM ports) with the following variables in input/provision_config.yml:

  • network_interface_type: lom

  • discovery_mechanism: bmc

To assign BMC NICs and route internet access to your target nodes, populate the values of bmc_nic_subnet, bmc_static_start_range, and bmc_static_end_range in input/provision_config.yml during the second run of the provision tool.
