The BMC and BlueField-2 logs can be collected using openbmctool as BMC and system dump.

Two types of dump are supported:

  • BMC dump, which is a collection of logs from BMC
  • System dump, which is a collection of logs from BlueField-2. To create a system dump, users must provide the BlueField-2 credentials and IP address of the tmfifo_net0 network interface.
