Raw Blame History

ironic-discoverd [1] is a StackForge project for conducting hardware properties discovery via booting a special discovery ramdisk and interrogating hardware from within it.

This ramdisk collects hardware information from the machine it's booted on and posts it to the URL provided via kernel argument 'discoverd_callback_url'.

The hardware information collected by the ramdisk are:

  • BMC IP address (may be required for associating with existing node in Ironic)
  • CPU count and architecture
  • Memory amount in MiB
  • Hard drive size in GiB
  • IP and MAC addresses for all NICs except the loopback
  • Various hardware data detected by python-hardware library

The machine is halted at the end of the process.
